Lamborghini Murcielago LP650-4 Roadster, 2010

Lamborghini Murcielago LP650-4 Roadster, 2010





The automobile Lamborghini has released the first photographs of a limited edition Lamborghini Murciélago LP650-4 Roadster.
The Roadster version of the Murciélago will offer an uprated 6.5 litre V12 engine that produces 650 hp (478 kW) along with permanent four-wheel drive: hence the model's LP 650-4 moniker.
With 660 Nm of torque, top performance is at 0-100km/h (0-62mph) in 3.4 seconds.
The top speed is around 330 Km/h (205mph).

The special edition model will be produced in a limited volume (50 units only), with a Grigio Telesto exterior that combines grey bodywork with a special bright orange Arancio LP 650-4 featured on the front spoiler and sills. The LP 650-4 logo applied to the car's exterior is recognition of the car's increased power. The car features orange brake calipers and a transparent V12-engine cover, which shows off the V12 engine behind the driver.

The interior features echo the car's striking grey-and-orange exterior: besides the orange touches, there is an asymmetric dash design, with black Alcantara Nera on the driver's side, including door panel and central tunnel, and black leather Nero Perseus on the passenger's side.

The increased power of the Murciélago engine, from 640 to 650 hp, will be unique to the Lamborghini Murciélago LP650-4 Roadster: it demonstrates even further the developments that Lamborghini is able to offer from a current engine, and creates the exclusive characteristic of the Lamborghini Murciélago LP650-4 Roadster.

Lexus GS 350, 2009

Lexus GS 350, 2009




The 2009 Lexus GS luxury sport sedan model line includes the V6-powered Lexus GS 350 and the GS 350 all-wheel drive (AWD), the V8-powered Lexus GS 460, and the only gasoline electric hybrid model in the segment, the Lexus GS 450h.

Engine/Transmission/Drivetrain/Performance
Optimized for low internal friction, the Lexus GS 350's 3.5-liter V6 engine produces 303 horsepower at 6,200 rpm and 274 lb.-ft. of peak torque at 3,600 rpm. A direct fuel-injection system provides much finer fuel-mixture control to improve both power and fuel efficiency. Dual Variable Valve Timing with intelligence (VVT-i) acts on both intake and exhaust valves to further enhance performance through a wide rpm range. A smooth-shifting six-speed transmission allows manual shifting when desired.

The Lexus GS 460's V8 produces 342 horsepower at 6,400 rpm and 339 lb.-ft. of peak torque at 4,100 rpm. The GS 460, like the GS 350, meets the EPA's Ultra Low Emission Vehicle (ULEV-II) certification. Lexus has been setting standards for powertrain smoothness since its inception, and the GS 460's V8 and eight-speed automatic transmission continue that tradition. The transmission, as the six-speed automatic in the Lexus GS 350 models, allows manual shifting for a more engaging driving experience, and to maximize performance in certain driving situations. The GS 460 can accelerate from zero to 60 mph in 5.4 seconds, the Lexus GS 350 in 5.7 (5.8 for AWD).

Chassis/Body/Suspension/Tires/Brakes
The Lexus GS combines proven chassis systems with advanced dynamic handling technology to provide both agile handling and the Lexus trademark smooth ride. The double-wishbone front suspension and multilink rear suspension virtually eliminate unwanted wheel-angle changes during suspension movement. The result is a natural, confident feel that's also spirited. A 34.1-ft. turning circle (35.4 ft. for GS 350 AWD) is comparable to that of smaller cars and helps make the GS highly maneuverable.

In all GS models, Brake Assist (BA), Electronic Brake-force Distribution (EBD) and the Anti-lock Braking System (ABS) help form a powerful safety front. EBD optimizes brake pressure at each wheel to help minimize body dive or sway during hard braking and cornering. Brake Assist is designed to determine if the driver is attempting emergency braking, and, if the driver has not stepped firmly enough on the brake pedal to activate the ABS, it will apply maximum braking force until pedal pressure is released.

Aluminum-alloy 18-inch wheels are standard on the Lexus GS 460 and available for the rear-wheel-drive Lexus GS 350, which features standard 17-inch wheels. For maximum handling capability, the GS 350 comes standard with 225/50R17 W-rated summer tires. The all-season 17-inch run-flat tires that are standard on the GS 350 AWD model are available on the GS 350 RWD. The Lexus GS 460 is equipped with 245/40R18 Z-rated summer tires or available all-season run-flats.

The GS 350's available all-wheel-drive system helps to enhance handling in diverse driving conditions. A planetary-gear center differential and a wet-type multi-disc clutch control front-to-rear power distribution. The system normally sends 70 percent of available power to the rear wheels to provide the traditional performance advantages of a rear-drive car and will vary the torque-split ratio from 30:70 to 50:50 in response to driving conditions and driver input. The AWD system's electronic-control strategy takes inputs such as steering and throttle angle from driver activity combined with vehicle signals from wheel speed and yaw rate sensors.

An Adaptive Variable Suspension (AVS) system, standard on the Lexus GS 460 and available on the GS 350, provides four settings, including "sport" for tighter, more precise control. AVS can automatically select appropriate suspension damping for driving conditions. The Lexus GS 460 also offers the advanced Active Power Stabilizer system that reduces body sway and enhances vehicle control during cornering. An Electronic Control Unit (ECU) calculates the force needed to counter excess body sway, which is then applied to the stabilizer bars by the front and rear actuators. The GS 350 models are equipped with Vehicle Stability Control (VSC) with traction control. The system can be disengaged with the "Trac Off" switch when the situation warrants doing so.

In the GS 460, the Lexus Vehicle Dynamics Integrated Management (VDIM) system integrates and manages a host of handling technologies, including VSC. Combining input from a variety of sensors, VDIM is designed to anticipate the onset of a vehicle skid or slide and then help correct the situation with a combination of braking, throttle, and steering control. VDIM integration helps to provide precise management for the Electronically Controlled Brakes (ECB), Variable Gear Ratio Steering (VGRS), Electric Power Steering (EPS), Vehicle Stability Control (VSC), Anti-lock Braking System (ABS), Brake Assist (BA), Electronic Brake-force Distribution (EBD), and engine torque via the electronically controlled throttle.

Electric Power Steering (EPS) in the GS 460 provides precise electric power assist using a DC motor built into the steering gear housing. Also in the GS 460, Variable Gear Ratio Steering (VGRS) can vary the steering from 2.7 turns lock-to-lock for low-speed maneuverability to a slower 3.2 turns lock-to-lock for highway-speed stability. VGRS also provides differential steering control, which helps correct for a delay in steering response - something that occurs in all vehicles - to help enhance driving feel during lane changes and other transitional maneuvers.

The GS 460's Electronically Controlled Brakes (ECB) is a brake-by-wire system. ECB translates brake pedal pressure into electric signals that, via computer control, help provide precise and optimized braking. Electronic control provides quick brake response when needed, helping the GS 460's VDIM system to anticipate and help correct skids before they occur. The ECB system is backed by conventional hydraulic brake control in the unlikely event of electronic failure.

Safety/Security Features
The Adaptive Front lighting System (AFS), standard on the GS 460 and optional for the Lexus GS 350, helps illuminate a curve as the driver steers into it. A Tire Pressure Monitoring system can detect a critical loss in pressure in one or more tires and alert the driver. The available Intuitive Park Assist (IPA) system uses ultrasonic sensors to detect objects close to the car's front and rear bumpers and alerts the driver accordingly. A steering-input sensor helps to better judge changes in distance to objects.

The Supplemental Restraint System (SRS) in the GS sedans includes variable-force front airbags for both the driver and front passenger. The GS features standard seat-mounted side airbags for the front seats, knee airbags for the driver and front passenger, and front and rear side-curtain airbags.

The rear back-up camera, available in conjunction with the optional navigation system, automatically projects an image of what its lens can detect behind the vehicle onto the navigation screen when the vehicle is in reverse gear.

The optional Pre-Collision System (PCS) in the GS models can help the driver avoid an accident. A millimeter-wave radar sensor helps detect obstacles in front of the car, while vehicle speed, steering angle and yaw-rate inputs help to determine whether a collision is unavoidable. In such a situation, PCS switches the Adaptive Variable-air Suspension to sport mode for optimal chassis response, preemptively retracts front seat belts, and pre-initializes Brake Assist so that increased braking will be applied the instant the driver depresses the pedal. The active-braking feature will automatically apply the brakes up to a deceleration rate of 0.3 g if the driver fails to react to system warnings.
Luxury/Comfort/Convenience
The standard Regency leather-trimmed, heated, 10-way power front seats (perforated leather trim on GS 460) are comfortably contoured for support on long trips. Ventilated front seats are standard for the Lexus GS 460 and available for the Lexus GS 350. A power-tilt and telescopic steering wheel helps ensure a comfortable driving position. The standard dual-zone climate-control system filters the air, and a standard rear power sunshade adds to passenger comfort on warm days.

All 4 windows offer one-touch up-and-down operation with jam protection. Both electrochromic auto-dimming side mirrors are power-retractable and feature automatic tilt-down to aid in parking when reverse gear is selected. A power trunk closer provides an added convenience on this extremely well equipped car.

The standard Lexus audio system features an AM/FM/cassette stereo and a 6-disc, in-dash CD changer. The system plays through 10 premium speakers while an Automatic Sound Levelizer (ASL) maintains consistent sound levels at varying vehicle speeds.
Luxury Options
Within the ultra-quiet Lexus GS interior, all styles of music come to life with the optional Mark Levinson® Premium Sound system. Featuring 11 channels of amplification with a total of 330 watts playing through 14 speakers, the system allows users to play both CDs and DVDs. DVD movies can be viewed on the color seven-inch touch screen when the parking brake is engaged.

The optional Lexus DVD Navigation System allows the driver to enter a destination by voice command. Visual support is greatly enhanced with a central screen featuring a high-resolution 800 x 480 pixel display in 32,000 colors. On-screen details are crisp and clean, and maps and roads are highlighted by 3-D shadow effects. Text display options include English, Spanish and French.

The DVD map database contains more than five million Points of Interest (POI). The database for Chicago, Detroit, Los Angeles, and New York includes a building footprint-display feature that can show graphic representations of buildings and structures to help the driver identify surroundings. System functions include multiple route calculations, route preview, simplified highway junction graphics, and a dual-map screen mode. Bluetooth® wireless technology integrates with the navigation system to allow the driver to make hands-free phone calls via its touch-screen control panel. Personal phone books can be transferred via Bluetooth, as well.
Exterior Design
The current generation GS sedans introduced the brand's L-finesse design language. A 112.2-inch wheelbase, long hood, pulled-back cabin and short rear deck create a confident, powerful stance for the GS. A sloped, vertical grille surrounded by four independent headlamps visually connects the current GS sedans with the previous-generation models while signaling the brand's design progression. The lower valance features integrated fog lamps, and a low 0.27 coefficient of drag (Cd) helps to minimize wind noise and maximize highway fuel efficiency.

Interior Design
Ultra-premium wood, polished-metal accents and leather trim endow the Lexus GS interior with a lavish yet high-precision feel. Touch points convey quality and controls that respond fluidly. The customer can choose from among three interior leather color combinations: Light Gray leather with Dark Gray Bird's-eye maple wood trim, Cashmere leather with Golden Bird's-eye Maple wood trim, or Black leather with Red Walnut wood trim. Each combination includes a matching wood and leather-trim steering wheel and shift knob.

The Lexus designers strive to keep controls simple and intuitive, avoiding needless complexity. The SmartAccess keyless entry and push-to-start ignition allow the driver to keep the access fob in a pocket or purse. Audio and climate-control systems are easy to understand and operate. The unique instrument panel lighting system relies on variable-transparency glass to minimize reflections from the gauge faces and to help optimize visibility in all lighting conditions.

Audi A1 e-tron Concept, 2010

Audi A1 e-tron Concept, 2010






The new e-tron model series from Audi will gain another new member at the 2010 Geneva Motor Show: The Audi A1 e-tron Concept is a Mega City Vehicle (MCV) with an innovative drive technology. It comes equipped with a powerful electric motor for zero-emission driving in the city. There is also an internal combustion engine on board that recharges the battery in exceptional circumstances. The Audi A1 e-tron Concept is very agile thanks to the 75 kW (102 hp) peak power of its electric motor.

The technology of the Audi A1 e-tron
The e-tron model family from Audi is just a few months old, but it already has a number of members, for each of which Audi has chosen a different drive technology. The first e-tron, which debuted at the 2009 IAA in Frankfurt/Main, is a near-series high-performance sports car with electric motors for all four wheels. The study shown at the Detroit Motor Show in 2010 is a lightweight, compact two-seater with two electric motors on the rear axle.

The Audi A1 e-tron Concept now presents another approach - a compact electric car in the premium class. The four-passenger, two-door MCV city car was designed specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The Audi A1 e-tron always drives on electric power; its internal combustion engine is only used to recharge the battery in isolated cases.
Audi A1 e-tron Concept

The integration of the new technologies shows the holistic approach that Audi is pursuing with electric mobility. The objective is to use the energy with the lowest possible losses. The precise interaction of the components, their intelligent packaging, and the efficient management of the current flows are the product of the expertise that the company has developed in this area.

The electric motor: 75 kW (102 hp) peak power

The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle's center of gravity. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).

The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the center tunnel used to choose between "Drive," "Reverse," and "Neutral" was taken from the first Audi e-tron.

The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.

The concept of the innovative Mega City Vehicle requires the electrification of key auxiliaries. The refrigerant compressor of the climate control system, for example, is electrically powered by a high-voltage electric motor that supplies only the amount of power needed at the time.

This increases system efficiency substantially compared to conventional concepts. Thanks to a special circuit, the climate control loop also functions as a heat pump that regulates the temperature of the cabin and the battery.

The power steering of the Audi A1 e-tron is electro-mechanical and thus particularly energy-efficient. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied. In addition, the servo unit received a new, demand-controlled electric vacuum pump.

The large electric motor powering the Audi A1 e-tron Concept can convert braking energy into electric current and feed it back into the electrical system. The high degree of recuperation benefits overall efficiency. The electric control actions are imperceptible to the driver, who notices only the familiar, precise, and perfectly controllable pedal feel.

The battery pack: a compact T arranged below the floor

The energy storage unit is arranged below the floor, where it is ideal for the center of gravity and weight distribution. The battery pack is shaped like a T, with the short "transverse beam" filling the rear section of the center tunnel and the "cross-beam" filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb).

The Audi A1 e-tron can drive 50 kilometers (31.07 miles) emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.

The range extender
The Audi A1 e-tron Concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button The fuel tank holds 12 liters (3.17 US gallons).

The great strengths of the Wankel engine are the nearly vibration-free and quiet operation, the small dimensions, and the extremely low weight. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms (154.32 lb). This weight also includes the special power electronics, the intake, exhaust, and cooling unit, plus the insulation and the subframe.

Driving experience
The first defining impression that the driver of the Audi A1 e-tron gets is that of nearly total silence. Even the Wankel engine in the back can barely be heard when it is running.

The second characteristic perception is the power of the electric motor, nearly all of which is available instantly and thrusts the Audi A1 e-tron forward with authority. The innovative Mega City Vehicle, which despite its complex drive technology weighs only 1,190 kilograms (2,623.50 lb) delivers zero-emission driving fun in a modern and sophisticated manner. The vehicle accelerates from 0 to 100 km/h (62.14 mph) in 10.2 seconds and has a top speed of more than 130 km/h (80.78 mph).

The Audi A1 e-tron can also cover longer distances if the range extender charges the battery. The extra range, which is intended primarily for interurban driving, is 200 kilometers (124.27 miles).

According to the draft standard, the two different operating modes yield a fuel consumption of only 1.9 l/100 km (123.80 US mpg), which corresponds to CO2 emissions of 45 g/km (72.42 g/mile). In electric mode, there are zero local CO2 emissions - the compact Audi A1 e-tron Concept is thus ecological and economical.

The third impression that the Audi A1 e-tron Concept makes is that of a larger car. The compact two-door boasts all of the strengths of the new A1 model series - the carefully tuned, sporty chassis with specially designed 18 inch alloy wheels and 215/35 R18 tires; the generous, "grown-up" interior; the excellent fit and finish; and a multitude of high-end equipment.
The dark shade "ebony" dominates the interior. The seats - with stone gray seams - and the headliner are in "Alabaster White".

Design
The concept car in Geneva has a special "Aqua Mint, pearl effect" paint finish; the contrasting roof arch is offset in "High Gloss Steel dark." As with the other two e-tron models, the 18-inch wheels with a 20-spoke turbine design convey the high-tech aspiration of the concept.
The rear diffuser with aluminum trim lacks tailpipes. This emphasizes the width of the vehicle and suggests the low emissions. The two front fenders are emblazoned with the "e-tron" logo.

The "Aqua Mint, pearl effect" exterior color carries over into the interior, where it adorns the door panels and the center console. The shift lever is a special leather-wrapped design; as is typical for the e-tron models, the start-stop button was placed in the front of the center console. A specially designed battery cover at the front of the car and the range extender engine with its cooling fins displayed under a sheet of glass in the luggage compartment also serve to visually underscore the clean technology of the Audi A1 e-tron Concept. And because an innovative drive concept also calls for innovative information management, the concept car features a freely programmable instrument cluster with a virtual display surface and innovative display and operating concept.

Infiniti G37, 2009

Infiniti G37, 2009





Powered by a potent 3.7-litre version of VQ family of petrol engines, the Infiniti G37 has been created to provide pure driving pleasure. There's a choice of rear- or all-wheel drive models with drive taken to the wheels via a slick six-speed manual or an advanced seven-speed automatic transmission.

The Infiniti G37's suspension - double wishbones at the front and a multi-link rear - deliver the perfect blend of sporting handling and superb ride comfort while the longer-than-class-average wheelbase results in a roomy cabin with a specific attention to rear knee room.

Just as significantly, the Infiniti G37 has been fine tuned to cope with European demands and expectations. Our higher average speeds place extra demands on aerodynamic efficiency, high speed stability, ride and handling and braking performance.

To meet those demands, a special Infiniti team working within Nissan's Technical Centre Europe (NTCE) has developed a package of changes to ensure the Infiniti G37 can compete with Europe's finest on level terms. Testing of the developments has been undertaken not just on private test tracks, but also on derestricted sections of the German Autobahnen at the infamous Nürburgring Nordschleife race track for handling and on British secondary roads for ride comfort.

Unlike many of its rivals, where judicious ticking of boxes in the options list is invariably required before a 'complete' car can be ordered, the Infiniti G37 is comprehensively equipped as standard. There's a full complement of standard safety equipment, too, while Infiniti's drive for quality results in exceptionally low Noise/Vibration and Harshness, uniformly small panel gaps and excellent materials inside the cabin.

It's clear that the Infiniti G37 is a car that can take on the establishment with a convincing credibility.

Exterior styling
With its long bonnet, long wheelbase and short overhangs, the Infiniti G37 blurs the boundaries between a four-door sedan and coupé. As well as providing a classic silhouette, the long bonnet is a visual reference to the Infiniti G37's 'front midships' engine location: the compact V6 is mounted in the front of the car, but as low and as far back as possible, with most of the block behind the front axle line. The result lowers the centre of gravity and helps to deliver the optimum front to rear weight distribution.

The low nose flows, via a curving roofline, to a high trunk to provide a feeling of motion even when the car is static. This is accentuated by a strong rising beltline, the flowing C-pillar and the muscular rear wheel arches.

To the front, the L-shaped headlamps and double-arch grille - complete with sculpted "twisted" horizontal blades inspired by traditional Japanese swords - have become Infiniti design elements helping to give the brand a distinctive face. At the rear the distinctive wraparound tail-lights are another Infiniti signature design. A neat, upswept spoiler integrated into the boot lid contributes to zero lift aerodynamics over the rear axle and completes the sporting look.

The overall effect combines obvious sporting potential with an understated sophistication that together capture the essence of the Infiniti brand.

Chassis and driving dynamics
Using the second generation version of Infiniti FM platform, the Infiniti G37 has an excellent front to rear weight balance thanks to its 'front midships' engine location while its long wheelbase and wide front and rear track adds to the car's overall handling stability.

Suspension design is fully independent and uses lightweight aluminium components to reduce weight as much as possible. With a racing-inspired double wishbone set up at the front, a multi-link arrangement mounted on a subframe behind and an extremely rigid bodyshell, the Infiniti G37 feels agile and surefooted with a refined ride.

Alignment changes are minimised at the front through use of a single pivot lower wishbone and a long upper link. The rear design separates the shock absorbers and springs, locating the dampers in line with the wheel centre to help reduce friction and reduce wind-up under acceleration.

Four-Wheel Active Steer (4WAS) is available as part of the Infiniti G37 Sport model (see standard and optional equipment). This helps improve handling performance by varying the front steering ratio and adjusting the geometry of the rear suspension according to steering input and vehicle speed.

An AWD version, known as the Infiniti G37x, uses Infiniti's ATTESA E-TS (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system, as found on EX37 and FX models will also be available.

The system uses an active torque distribution management system with an active centre clutch for smooth starts, greater grip and better manoeuvrability on slippery surfaces without compromising the vehicle's rear-wheel drive performance characteristics on dry roads.

By constantly adjusting the power - sending anything from 50 per cent to the front, to up to 100 per cent to the rear - the system generates greater control without sacrificing sportiness and true performance dynamics.

All versions of Infiniti G37, whether rear- or all-wheel drive come with Electronic Stability Program (ESP), helping to enhance vehicle stability under a variety of driving conditions. A Viscous Limited Slip Differential (VLSD) is included in the Sport model.

Power-assisted four-wheel vented disc brakes have a four-channel, four-sensor Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). The power steering system is a vehicle-speed-sensing design, which provides optimum steering effort at both high and low vehicle speeds.

Engine and powertrain

At the heart of a sports sedan there needs to be a sporting engine… and this is another area where Infiniti G37 delivers on its promise. It is powered by a new 3.7-litre version of VQ engine family. Regularly honoured in independent awards the world over, the twin cam 24 valve V6 produces over 310PS and an impressive over 350Nm of torque.

Among its many features, the lightweight aluminium engine features a bed-plate construction. A technique that has been used in motor racing for many years, the resulting two-part construction of the cylinder block is more rigid than a single piece casting. Among engine specialists, this configuration signifies a high-performance sporting engine which is uncompromisingly designed for the highest strength and reliability.

Other benefits include reduced vibration levels and higher engine speeds to be reached consistently without damage.
The VQ37 unit also features V-VEL (Variable Valve Event and Lift) technology to optimise efficiency and, in turn, the balance between power, response, fuel efficiency and emissions.

V-VEL continually alters valve lift and therefore the quantity of air in the combustion chamber. At partial throttle - in stop-go city traffic, for example - it will make a small lift thus achieving a more precise fuel/air mix with lower quantities of both to improve fuel consumption. At full throttle, the valve lift is greater, inducting a larger quantity of air into the combustion chamber.

The result is a more powerful combustion phase increasing torque and power… this is felt tangibly by the driver in the instant throttle response, which is a result of using the valves to control air-flow into the cylinder - eliminating the slight delay that can be felt with engines using a conventional throttle butterfly.
Precise mapping of the engine control unit (ECU), meanwhile, helps the engine provide a progressive 'swell' of power and torque, providing a 'building wave' of acceleration rather than a peaky power delivery.

As well as a smooth shifting six-speed manual transmission, the Infiniti G37 will be available with a new seven-speed automatic option with Adaptive Shift Control (ASC) allowing a downshift blip control.
With its additional forward gear, the new automatic transmission has a wider spread of ratios which benefits both fuel consumption and drivability. The seventh speed is effectively an overdrive ratio, returning improved fuel economy on a steady throttle without compromising in-gear flexibility for overtaking.

Shift points are tuned to keep the engine in the largest part of the torque curve, ensuring there is always a healthy reserve when the driver wants to overtake. The linked ASC system switches between three different programs depending on input from the major control systems throughout the car.

Interior environment
The Infiniti G37's interior is an environment designed to appeal to driver and passengers alike. Quality materials provide the warmth and comfort expected in a premium car, yet the driver's quarters have a 'scooped-out' design to emphasise the concept of a cockpit in direct contrast to the open, spacious design of the passenger area.

The dashboard and centre console adopts Infiniti design DNA with a 'double wave' upper section linked to a central vertical spine for a feeling of solidity. With roots in Japanese design, 'Washi-style' aluminium accents can be found through the cabin. Washi is a form of elegant Japanese handmade paper and textured aluminium trim inserts can be found on the centre console, the instrument binnacle and the door panels. Automatic versions have the option of African rosewood inserts.
At 2850mm, the wheelbase is longer than its key rivals which translates directly into more interior space for rear passengers.

Safety
A full complement of six airbags can be found as standard in Infiniti G37. The front seats incorporate hip and thorax bags, while there are front-to-rear curtain airbags for protection in a side impact.

As well as offering occupants the highest level of crash protection, Infiniti has developed a pop-up bonnet to offer greater protection for pedestrians: it is a standard fitting on Infiniti G37.
In the event of a collision, a small pyrotechnic charge raises the trailing edge of the bonnet close to the lower edge of the windscreen. This creates a larger buffer between the bonnet and the 'hard points' of the top of the engine, providing a more yielding surface and helping to reduce potential injuries.

Standard and optional equipment
Right from the outset, Infiniti G37 has been designed to offer a full complement of standard equipment rather than force prospective customers to open their wallets even wider when choosing the model of their choice.

That means every Infiniti G37 has the Infiniti I-Key with smart access as standard. As soon as the vehicle identifies a pre-programmed I-Key in the vicinity, the door can be opened and the car started without the key needing to leave a pocket or handbag.
Personal settings for the driver's seat, steering wheel and exterior mirrors can be programmed into the key (on any car specified with leather seats) so that the key holder won't have to reposition anything if the car has been driven by anyone else.

Standard are a six-disc, seven speaker CD audio system, Bluetooth mobile phone connectivity, cruise control, power seats, auto-dimming rear view mirror, front and rear parking sensors, automatic lights and wipers, 18-inch alloy wheels, six airbags and integrated fog lamps.

The steering wheel - leather trimmed and double stitched by hand - incorporates controls for the audio system, cruise control and telephone. The Infiniti G37 also has an adaptive front-light system (AFS) as standard. The Bi-Xenon headlamps are linked to steering inputs and automatically follow the path of the front wheels to provide a wide spread of light around corners and on winding roads.

Unique to Infiniti is the use of "Scratch Shield" paint. A special highly elastic resin has been combined with a conventional clearcoat to increase the paint's flexibility. A car painted with "Scratch Shield" paint can exhibit up to five times fewer scratches that a conventional clearcoat when exposed to the same conditions.

When exposed to heat, "Scratch Shield" paint repairs fine scratches, restoring painted surfaces close to their original state. It will allow a Infiniti G37 to retain the brilliance of its exterior colour long after rivals have lost their glow.

Options are largely grouped into a couple of special packages. The leather package, as its name implies, includes leather seats, heated in the front, power lumbar support in the driver's seat and eight-way adjustment for the passenger seat in place of the standard four-way adjustment.

The Sport Model provides a different style of 18-inch alloy wheel, tyre pressure monitoring, a viscous limited slip differential and sports settings for the suspension, steering and brakes (forged aluminium opposed brake callipers).

It also features Four-Wheel Active Steer (4WAS). By monitoring steering angle and vehicle speed data, the 4WAS controller calculates the difference between current performance and optimum target data which is pre-programmed into the system.

The front and rear steering angle (the amount the wheels are turning in comparison to the straight-ahead position) can then be altered to match the target performance data - which is based on the optimum possible vehicle dynamics.

Benefits of active steering include greater stability at high speed, adding to the passive safety equipment of the vehicle and working in combination with the ESP system. The driver will also be able to enjoy an even greater level of agility when cornering. 4WAS is not available with four-wheel drive.

The heated and leather covered seats have thigh extensions for greater support, while the driver's also has power operated lumbar and lateral support. As with the leather package, the passenger seat is upgraded to 8-way power adjustment. The sports package is completed by aluminium pedals and foot rest and exterior 'S' badging.

Finally there's a multimedia package which includes satellite navigation, a rear view camera and a Bose premium audio system. The navigation system covers more than 30 European countries and offers Birdview as well as conventional displays on the integrated eight-inch colour screen. Voice recognition for navigation and the phone is incorporated and the screen is also used by the rear view camera to relay real time images from behind the car whenever reverse gear is selected.

The Bose premium sound system has been specially designed for Infiniti G37. The loudspeakers in the 10 unit system features lightweight yet powerful neodymium magnets with an innovative driver design allowing the speakers to produce the output of a larger, heavier speaker.

Nd magnets are smaller and lighter than conventional ferrite magnets found in most speakers but are just as powerful. As a result, they help the system deliver a full rich sound while adding less weight to the vehicle. In addition, an innovative design approach, powerful digital amplifier, custom equalisation and digital signal processing help reproduce music with clarity, spaciousness and realism.

The audio system itself incorporates an in-dash six-disc CD player with AM/FM radio and has an RCA AUX-in jack socket for MP3 players.

The final option is an Intelligent Cruise Control (ICC) which uses brakes, throttle and laser sensors to help maintain a set distance between the Sedan and the car in front. In automatic versions of the Infiniti G37, the software reduces driver's workload even more allowing ICC to work from 0km/h thanks to the "Full Speed Range" feature.

Quality
Infiniti is synonymous with vehicle quality, and that's something that doesn't happen by accident.
On the Tochigi production line in Japan every vehicle - not just every tenth - is laser scanned to ensure that panel gaps are within prescribed limits.

During the design and development phase, new models are exhaustively tested not just at Infiniti's Hokkaido proving ground but also at the Tochigi and Motegi test and race complexes in Japan. Infiniti also has a vast 12.34 million square metre hot weather testing base in Arizona and uses the famed Nordschleife circuit at the Nürburgring in Germany.
Testing every Infiniti in the harshest of conditions and over thousands and thousands of kilometres ensures the durability and peace of mind that buyers can expect from the products.

Volvo C30, 2007

Volvo C30, 2007






With the new C30, Volvo makes its debut in the segment for two-door premium cars.
The sporty design, with two doors, four individual seats, and a glass tailgate, aims to give a young and dynamic group of customers "a Volvo of their own."

During the development phase of the C30 project, Volvo Car Corporation has organised customer clinics in a number of European countries. People living in urban areas with accelerating careers and an intensive lifestyle were invited to judge the car's design and technical content.

For an active life in urban areas
Volvo has focused primarily on singles, or couples without children who see the car as an entertaining tool for keeping up with their intense lives. When they buy clothing, home furnishings, or electronic devices, design and brand are very important factors - and they choose cars in the same way.

Design Concept preview in Detroit
The international customer clinics confirmed that the project was on the right track - and at the Detroit Motor Show in January 2006, Volvo offered a glimpse of the coming production model by displaying the C30 Design Concept.

The concept car was subsequently put on display at numerous auto shows, and Volvo Cars has also organised international events with specially invited guests, in cities such as Milan.

Dynamic front and fast silhouette
The design of the production-ready model is in tune with the Volvo C30 Design Concept. The front will retain its dynamic character, with the angled headlamps and the low, wide grille.

Viewed from the side, the distinct wheel housings in contrasting materials, and the sloping roof give the new C30 a fast silhouette, which is further enhanced by the extreme boat-shape of the side windows. This is created by the narrowing roof and the wide shoulders.

The shoulders at the rear are powerfully rounded and are accentuated by the horseshoe shaped lighting pattern of the tail lamps, and the glass tailgate. The spoiler at the upper edge of the tailgate is available in two different versions.

Styling for individualists
The possibility of adapting the car to their personal taste is high on the wish list among the intended buyers.

A specially designed body kit with larger exhaust pipes is available fully colour coordinated or in dual tone. To further personalise the car, the body kit can be combined with a lowered sport chassis and 18" wheels.

The body kit is available in many colours to create a wide range of possibilities for exciting personal combinations.
Styling items available for the interior are a sport steering wheel and sport gear lever with aluminium inlays, brushed aluminium pedals, and specially designed C30 carpets.

The Volvo C30 will be introduced with, for example, an entirely new colour: Cosmic White Pearl. Equipped with the body kit in brown Java Pearl, the car will strongly recall the Volvo C30 Design Concept.

Room for four adults
The new C30 has room for four adults thanks to the two separate seating positions in the rear seat, with generous head- and legroom. The rear seats are slightly centred to provide a feeling of space and a good forward view. It also makes communication between front and rear occupants much easier.

The space between the seats also makes the thin, visually floating centre stack clearly visible from the outside through the glass tailgate.

The centre stack is available in four different versions. Completely new is the Virtual White inlay, inspired by the modern, glossy surfaces of the worlds of sport and computers. The same material is also used in the doors.

A striking version with surf-patterned aluminium is also available as an accessory, and has been inspired by the C30 Design Concept.

Personal interior choices
The interior program has also been designed to meet the target group's expressed wishes for personal choices. Even the base program offers, for example, upholstery in red and blue. There are also black upholsteries that can be accentuated with contrasting red carpeting.

The volume target is 65,000 cars a year. Volvo expects that 75 percent of the buyers will be in Europe. The largest markets are Italy, Germany, Spain, Great Britain, the USA, France, Sweden, and Holland.

The new C30 will make a firm impression in a segment that is new for Volvo - and the intention is that at least three out of four Volvo C30s will find customers who do not currently drive a Volvo.

BMW 320d Efficient Dynamics, 2010

BMW 320d Efficient Dynamics, 2010




Teaming up with the BMW 320d, the new BMW 320d Efficient Dynamics Edition is being presented for the first time at the 2009 Frankfurt Motor Show. This unique saloon combines fuel consumption of just 4.1 litres diesel/100 kilometres (equal to 68.9 mpg imp) and a CO2 rating of 109 grams per kilometre in the EU test cycle with engine output of 120 kW/163 hp.

The 2.0-litre four-cylinder diesel engine of this high-tech model boasts an all-aluminium crankcase, turbocharging with variable intake geometry and common-rail direct fuel injection complete with piezo-injectors. With the engine and the entire car modified once again for an even higher standard of efficiency, this unique saloon targeted above all at the German, Italian, French and Spanish markets comes with optimised aerodynamics, an extra-long final drive ratio, and an innovative two-mass flywheel incorporating a centrifugal-force pendulum.

The BMW 320d Efficient Dynamics Edition the most fuel-efficient and lowest-emission car in BMW's current model range. In the fiercely contested midrange segment it is an unparalleled, highly attractive premium offer for the truly demanding and progressive customer focusing primarily on superior economy and the environment, without wishing to forego the sporting driving characteristics so typical of a genuine BMW.

The enhanced efficiency already offered by the existing models in the BMW 3-Series thanks to BMW Efficient Dynamics making these cars superior to their competitors, is now raised to an even higher level in the BMW 320d Efficient Dynamics Edition.

4-cylinder diesel engine with optimised efficiency and superior performance all in one.

The BMW 320d Efficient Dynamics Edition is powered by a four-cylinder diesel engine specifically optimised for even greater fuel economy and emission management and, therefore, for a standard of efficiency never seen before. All this comes from the 2.0-litre four-cylinder power unit with its all-aluminium crankcase, turbocharging and the latest generation of common-rail fuel injection featured with various power stages also in the BMW 316d, the BMW 318d and the BMW 320d. The engine specially conceived for the BMW 320d Efficient Dynamics Edition develops maximum output of 120 kW/163 hp at an engine speed of 3,500-4,200 rpm and peak torque of 360 Newton-metres/265 lb-ft all the way from 1,750 to 3,000 rpm.

The engine stands out in particular through its sporting and dynamic power from low revs. The innovative centrifugal-force pendulum incorporated in the two-mass flywheel, together with the longer transmission ratio, serves to significantly reduce the level of engine speed at all road speeds relevant in practice in the BMW 320d Efficient Dynamics Edition. The shift in load points beneficial to fuel economy and emissions goes together in this case with full maintenance of the spontaneity and running smoothness so typical of a BMW diesel.

Centrifugal pendulum in the two-mass flywheel for smooth and comfortable motoring without vibrations even at very low engine speeds.

To ensure smooth driving characteristics free of vibration also when driving at particularly low engine speeds, the power unit of the BMW 320d Efficient Dynamics Edition features a so-called centrifugal pendulum efficiently compensating any unsmoothness in running characteristics typically encountered at low revs. This innovative component is integrated in the engine's two-mass flywheel where it dampens the vibrations generated under load, thus ensuring comfortable and acoustically optimised development of power and performance all the way from low engine speeds.

This increase in motoring comfort will encourage the driver to use a higher gear more often or, respectively, not to shift back as he otherwise would do. But when accelerating the BMW 320d Efficient Dynamics Edition still offers the driving behaviour and agility so typical of BMW.

The driving dynamics characteristic of a BMW are borne out also by the car's acceleration to 100 km/h in just 8.2 seconds and by the BMW 320d Efficient Dynamics Edition accelerating in fifth gear from 80-120 km/h in 9.6 seconds. Top speed is 225 km/h or 140 mph.

The BMW 320d Efficient Dynamics Edition comes with the complete range of technologies serving to reduce both fuel consumption and emissions and already featured as standard on the other models in the BMW 3-Series. Brake Energy Regeneration, for example, serves to concentrate the generation of electric power for the on-board network on overrun and the application of the brakes, thus avoiding even the slightest increase in fuel consumption. The Auto Start Stop function, in turn, switches off the engine even during a short stop in traffic, avoiding any unnecessary consumption of fuel while idling. The gearshift point indicator on the BMW 320d Efficient Dynamics Edition, to mention yet a further example, tells the driver in good time when to shift gears in the interest of optimum efficiency. And like the detachable climate compressor, EPS Electronic Power Steering operates only when needed, again in the interest of maximum efficiency.

The electric motor featured within the EPS system therefore takes up energy only when really needed for power assistance or when required by the driver. Active cooling through air flap control and tyres with reduced roll resistance also serve to enhance the car's efficiency, and the BMW 320d Efficient Dynamics Edition is likewise fitted with a diesel particulates filter close to the engine. It almost goes without saying, finally, that the BMW 320d Efficient Dynamics Edition fulfils the EU5 emission standard in full.

The fuel economy and emission management also featured in the other models in the BMW 3-Series are combined in the BMW 320d Efficient Dynamics Edition with additional innovations, which, together with the decrease in engine power on the BMW 320d by 10 kW or 14 hp, serve to reduce fuel consumption and emissions to an even lower level, below the CO2 standard of 110 grams per kilometre relevant to taxation in many countries.

These additional features include a longer final drive ratio and the lower chassis and suspension of the car. Newly developed Aero wheel rims in turbine wheel design - the only optical sign of distinction on the car to be seen from outside - improve the level of aerodynamics to an even higher standard, giving the BMW 320d Efficient Dynamics Edition a drag coefficient of just 0.26.

Within the BMW 3-Series the BMW 320d Efficient Dynamics Edition is the so far most consistent implementation of the BMW EfficientDynamics development strategy, offering the motorist who really appreciates the premium character and sporting driving qualities of a BMW 3-Series and at the same time attaches utmost significance to superior economy exactly the right choice in the midrange market segment.

Comparing the efficiency of all models in this segment, BMW, introducing the BMW 320d Efficient Dynamics Edition, is once again moving a step ahead of the competition. And following BMW's general policy, the improvement of efficiency offered by this innovative technology does not even require the payment of a higher price for the BMW 320d Efficient Dynamics Edition, which therefore comes at the same price as the "regular" BMW 320d, which naturally is still included in BMW's model range.

BMW Efficient Dynamics Concept, 2009

BMW Efficient Dynamics Concept, 2009






The BMW Vision concept car clearly demonstrates that the EfficientDynamics objectives are fully compatible when applied to a sports car. Conceived as a 2+2-seater with plug-in full-hybrid technology, the unique car combines the performance of a BMW M vehicle with a standard of fuel efficiency and emission management that exceeds even the current levels achieved by the latest small cars. The outstanding result is made possible by the combination of BMW ActiveHybrid components with an extremely economical combustion engine, and outstanding aerodynamic qualities.

BMW Efficient Dynamics Concept is the result of a "clean-sheet" development process to ensure that the correct achievements were made in the areas of efficiency, driving pleasure, technology, and emotional design. BMW Efficient Dynamics Concept is the most comprehensive implementation of the EfficientDynamics philosophy seen so far. The powertrain provides a top speed limited electronically to 155 mph, with acceleration to 100 km/h in 4.8 seconds. Average fuel consumption in the EU test cycle is 3.76 liters/100 kilometers, equal to 62.6 mpg, and the CO2 emission rating is 99 grams per kilometer. CO2 emission management is even more outstanding when driving in the all-electric mode after charging the battery from a plug-in source: Taking all emissions in the generation of electricity into account, as prescribed by the EU formula, the car's emission rating is just 50 grams per kilometer.

The power and performance are made possible by combining a fuel-efficient 3-cylinder turbodiesel with one electric motor on each axle. The intelligent combination of these units, together with precisely controlled energy management, simultaneously enhances the dynamic performance and the efficiency of the car. Overall system output is 356 horsepower, and peak torque is 590 lb-ft. The special arrangement of the two motors and diesel engine allows all-wheel drive when driving in all-electric mode. The result is minimum power loss and a harmonious transmission of the power available under all conditions.

BMW EfficientDynamics Concept for the first time conveys the dynamic look of a BMW sports car to a hybrid vehicle. Developed with decades of experience in Motorsport, the body of this unique sports car is a result of intelligent lightweight technology and aerodynamic efficiency. In the design of the interior, the focus was likewise on both the fascinating driving experience and, in particular, on transparent, hands-on technology and maximum reduction of weight.

Turbo diesel engine with unprecedented specific output.
The combustion engine is a cutting-edge turbodiesel featured for the first time in the BMW EfficientDynamics Concept car. Displacing 1.5 liters on three cylinders, the engine consistently follows the downsizing principle of using a relatively small engine combined with a turbocharger to reduce fuel consumption.

The specific output of 109 hp per liter sets a new benchmark in diesel technology. The power delivered by the turbodiesel is conveyed to the rear axle by means of a double-clutch transmission (DCT). This advanced transmission technology, which already offers a particularly dynamic driving experience in BMW's M3 and Z4 Roadster, allows the driver to shift gears without the slightest interruption of power. BMW EfficientDynamics Concept features a newly-developed version of BMW's DCT with six speeds for maximum efficiency and flexibility.

Two electric motors for full-hybrid drive.
The combustion engine is supplemented by two electric motors. Consistently applying the BMW ActiveHybrid philosophy, development engineers followed the principle of "Best of Hybrid," choosing the optimum combination of a hybrid synchronous motor on the front axle and a full-hybrid system at the rear.

The driver benefits from the efficiency of the electric motors over a far wider speed range than with a conventional hybrid car. The rear axle comes with a second-generation full-hybrid system corresponding to the technology in the BMW ActiveHybrid 7 production model. The compact electric motor positioned between the diesel engine and the DCT outputs a consistent 33 horsepower and is able to reach a peak of up to 51 hp. Maximum torque for the rear electric motor is 214 lb-ft, the power, either supporting the diesel engine or in all-electric motoring.

The engine, a hybrid synchronous motor, offers continuous output of 80 horsepower and peak torque of 162 lb-ft. Extra power of 112 horsepower is available for a period of up to 30 seconds, and, for a 10-second "burst," the electric motor is able to develop 139 horsepower. The power is transmitted through a 2-stage, single-speed reduction gearbox.

The lithium-polymer battery for electrical energy.
The energy cells featured in BMW EfficientDynamics Concept are housed in a chassis element running from front to rear through the middle of the car. The front unit is the lithium-polymer complex, an ongoing development of the lithium-ion battery. Overall, BMW EfficientDynamics Concept comes with a total of 98 lithium-polymer cells, each offering a capacity of 30 amp/hours and developing continuous output of 600 Amps at a voltage of 3.7 V. For a period of 30 seconds, each cell is even able to develop maximum output of 1,200 Amps.

The serial arrangement of the lithium-polymer cells serves to generate nominal voltage of 364 volts, the gross storage capacity of the battery is 10.8 kW/h. With an unusually high discharge capacity of 80 percent, the battery delivers 8.6 kW/h for driving the car. This superior performance comes on overall weight of the entire energy storage system of just 187 lb. A further advantage is that through their optimum dimensions tailored to the specific qualities and features of the car, the lithium-polymer cells, together with the operating strategy chosen with a concept of "forward looking" energy management, reduces the thermal load acting on the battery to such an extent that there is no need for active cooling.

The Plug-in solution: convenient charging of the electric power system from a conventional power socket.

Brake Energy Regeneration captures electric power generated while driving without additional fuel consumption, which is subsequently used to supply power to the electric motors and on-board network. A further option is to connect the lithium-polymer cells to a conventional power socket for a simple and efficient charge process, using a plug-in connector in the front-right wing of the car. Connected to a standard EU power outlet (220 V, 16 Amps), the system requires a maximum of 2 ½ hours to fully charge the lithium-polymer cells. And wherever a power source with higher voltage and amperage (380 V, 32 Amps) is available, the charge time is an even shorter 44 minutes.

The Fuel efficiency and emission management opening new dimensions in hybrid technology.

The power delivered by the two electric motors and single diesel 3-cylinder engine gives the BMW EfficientDynamics Concept a level of performance superior to anything provided so far by a hybrid vehicle. Acceleration from a standstill to 100 km/h, for example, comes in just 4.8 seconds and the car could exceed its electronically-limited 155 mph top speed.

The fuel efficiency and emission management now reach a standard only achieved, if at all, by far less powerful small cars conceived for city traffic and short distances. Applying the criteria of the EU test cycle, BMW EfficientDynamics Concept offers average fuel consumption equal to 62.6 mpg. CO2 emissions, in turn, are 99 grams per kilometer. These consumption and emission figures are measured on a consistent internal power balance, meaning that the batteries and storage media for electrical energy maintain the same charge level throughout the entire test cycle (with the same level at the beginning and end) and are charged while driving only by the car's on-board systems.

As a plug-in hybrid, BMW EfficientDynamics Concept is able to cover the entire drive cycle for measuring fuel consumption also with its combustion engine completely switched off. Then, to subsequently charge the lithium-polymer cells to the same status as when setting off, all the driver has to do is connect the car to an external power grid. To determine the consumption of electric power, the only requirement is to compare the charge level of the battery before and after the test cycle. Applying this measurement process, the BMW Efficient Dynamics Concept car consumes 17.5 kW/h per 100 kilometers, equal to a CO2 emission rating of just 50 grams per kilometer in the EU test cycle.

To determine the total volume of CO2 emissions when driving in the all-electric mode, new legal standards for measuring the level of fuel consumption are currently being prepared for hybrid and electric cars with a plug-in power supply. Applying this calculation method, the CO2 emission ratings generated by BMW Efficient Dynamics Concept are reduced further to just one-third of the original figure of 99 grams per kilometer. Clearly, this significant reduction of emissions opens up a new dimension in BMW's EfficientDynamics development strategy in this unique concept car.

Aerodynamic qualities reflecting BMW's Motorsport experience.
BMW EfficientDynamics Concept also takes a new approach in its design and streamlining, the body and the interior clearly expressing the unique combination of supreme efficiency and the sporting performance of the brand. Following BMW's design language, this concept car visualizes both highly efficient aerodynamics and intelligent lightweight construction.

In its design, BMW Efficient Dynamics Concept differs from the usual low-emission car concepts. The principle of "form follows function" is not just for the overall look of the car, but embraces each and every detail. Measuring 48.8" in height and boasting a sweeping, arch-like roofline, BMW EfficientDynamics Concept offers the slender silhouette of a classic Gran Turismo. With the combustion engine fitted in front of the rear axle, the designers have succeeded in giving the car a very low front end, with the flow of air being further smoothened by active louvers in front of the radiator, which close completely when the need for cooling air is low. This efficient function follows in the footsteps of the active air flap control already used as a feature of BMW EfficientDynamics in some of BMW's current production models. As a further highlight, BMW EfficientDynamics Concept guides air smoothly and exactly as required into the car through an active air intake at the front.

Overall vehicle concept for a drag coefficient of just 0.22.
To further optimize the aerodynamic qualities of the entire vehicle and keep rolling resistance to a minimum, BMW Efficient Dynamics Concept comes with tires and wheels of quite unusual size on a sports car. The tires measure 195/55, while large 21-inch wheels provide a contact surface on the road otherwise offered only by a much wider tire. In combination with the sophisticated axle geometry, this ensures agile driving behavior.

The extra-large wheel covers extending over part of the tire flanks add to the unique, very different look of BMW Efficient Dynamics Concept from the side. The blade profile integrated in the wheels serves furthermore to reduce the negative effect of the turning wheels on the overall aerodynamics of the car. In all, these features optimizing the aerodynamic qualities of the car give the BMW EfficientDynamics Concept car a very low drag factor (CX) of just 0.22.

Technological look as a strong impression of intelligent lightweight construction.
In both exterior and interior design, BMW EfficientDynamics Concept stands out clearly as a strong spearhead in technology. Many components of the vehicle are presented in full view expressing the "transparent" character of the car as a powerful visual feature of lightweight technology. The chassis and suspension of BMW EfficientDynamics Concept are made completely of aluminum; the roof and the outer skin on the doors are made almost completely of a special polycarbonate glass automatically darkening as a function of the light shining on the car.

Measuring 181.1" in length, 74.8" in width and 48.8" in height, this unique concept car offers ample space for up to four passengers and their luggage. Thanks to the consistent lightweight construction strategy applied on the car, curb weight is 3,076 lb, with the center of gravity remaining very low. In its power-to-weight ratio, the BMW EfficientDynamics Concept car is far superior to all other hybrid cars, achieving the same standard as extremely dynamic sports cars with a conventional combustion engine.

Carrying a maximum payload of 981 lb, this unique 2+2-seater is fully suited for everyday traffic. Luggage capacity of 5.3 cu ft, in turn, allows the driver and passengers to conveniently take along two golf bags. And to meet additional loading requirements the backrests of the two rear seats may be tilted down individually to provide extra storage space.

Interior: innovative lightweight construction and unprecedented orientation to the driver.
Innovative layering technology provides an unprecedented symbiosis of function and stylish shapes intentionally reduced to a minimum, consistently implementing and visualizing the lightweight principle also inside the car.

Specific components such as the central air vent not only serving to enhance motoring comfort but also acting as part of the cockpit, perform several functions in one. This multi-functionality is then presented visibly within the car, the use of particularly sophisticated materials providing a highly attractive combination of innovation in technology and quality clear to the eye and the touch of the surface.

This interaction of lightweight construction and individual well-being also comes out clearly in the design of the controls and switches, with a leather band, for example, running round the aluminum gear selector lever on the center console. Materials combining lightweight technology and all the qualities required are also to be admired all round the cockpit of BMW Efficient Dynamics Concept, giving the car an unusually generous feeling of space for a 2+2-seater. The body-contoured seats, for example, are made up of a kevlar shell, a backbone structure, and seat padding with personalized fillings. Clearly, this combination alone ensures comfort at a minimum weight. The driver's and front passenger's seats are connected firmly to the center console to form a joint interior "landscape", while the rear seats anchored on the floor would appear to be hovering in space. Natural materials and light colors on the seat upholstery and all interior linings underline the light, sophisticated and sustainability-oriented atmosphere within the passenger compartment.

The instrument panel is deliberately padded only where technical components have to be appropriately covered, thus making an important contribution to passenger safety in the event of a collision. The instrument cluster played a fundamental role right from the start in the design process, serving as the starting point for all surfaces within the interior and thus creating a particularly powerful rendition of that driver orientation typical of BMW.

Innovative light technology: providing clear signals to the outside and offering soothing ambient illumination inside in a unique symbiosis.

LED lights at both the front and rear end of BMW Efficient Dynamics Concept provide an innovative combination of the symbols typical of the brand and clear design language oriented towards trendsetting technology. The distinctive look of the dual round headlights characteristic of a BMW is emphasized in particular by the use of LED technology. The rear lights are integrated also in their function into the design of the entire rear section, forming part of the rear air deflector and thus merging completely into the rear contour.

Extremely flat and compact, the rear lights are made up of innovative LED units forming a smooth and consistent red surface when not in use. Only when used do the respective light chambers take on the appropriate color such as yellow on the direction indicators. This innovative light technology also provides an intense symbiosis of the exterior and interior, again promoting and further refining the driving experience.

This is also why the ambient illumination of the interior comes with new features and qualities, the light sources within the passenger compartment being fed from the positioning lights at the side, the rear lights and the brake lights, thus changing the atmosphere created by the lights within the car as a function of driving conditions.

The optical impression conveyed by BMW Efficient Dynamics Concept also results in other areas from the symbiosis of the exterior and interior, eliminating the conventional barriers between the two. The lines within the interior, for example, continue on to the innovative design of the engine compartment lid, while in its shape the third brake light positioned higher up on the car follows the structure of the glass roof and tapers to the outside where the roofline moves down gently to the rear.

Overhead doors for convenient access to all seats.
The doors on BMW Efficient Dynamics Concept open up like bird's wings, turning on pivots in the front roof column at the level of the side direction indicators. Since the car has no B-pillars, the large door cutouts ensure convenient entry also to the rear seats. The pivots on the doors also provide the base for the exterior mirrors, thus forming an ideal combination of function and aesthetic design. The structure of the doors is also characterized by several layers of materials on top of one another and the optical and functional symbiosis of the interior and exterior this technology is able to offer. Made up of three layers, the overall structure comprises the outer glass surface, an interim load-bearing layer, and the interior cover with its particularly smooth shapes and fl owing forms clearly visible to the passengers, layering technology again, therefore, opening up new perspectives.

The large glass surfaces extending far down on the body also provide a strong optical impression of the low seating position close to the road. And at the same time a stable sidebar ensures the body stiffness and crash safety naturally required on every vehicle. Flowing to the inside at its central point, this safety element also serves as an armrest. This interplay of the three layers also helping to minimize the weight of the car continues on the trim bar running along the door and extending out of the armrest, finally flowing into the outer door opener on its path from inside to outside.

Lamborghini Gallardo LP550-2, 2010

Lamborghini Gallardo LP550-2, 2010




Automobili Lamborghini now presents a model in his honour and bearing his name - the Lamborghini Gallardo LP550-2 Valentino Balboni.
The latest version of the Gallardo, Lamborghini's most successful model of all time - overall, more than 9,000 units of the model range have already been produced - boasts not only its own distinctive design and exclusive equipment, but its technology is unique too, as indicated by the model badge: the 550 stands for the power output in hp and the 2 is for rear wheel drive.

For several decades, Valentino Balboni has had a distinct influence on the character of the super sports car bearing the sign of the bull. With his fine-tuning and testing work, he has helped to shape many automotive legends, from the Lamborghini Miura of the 60s through to the current Lamborghini Gallardo and Lamborghini Murciélago models. Balboni was hired in 1967 by company founder Ferruccio Lamborghini himself. From early on, it was evident that the young Balboni had a special feel for cars, that most sensitive of all instincts that connects to the 'life blood' of an automobile and defines the soul of a test driver.

Limited to 250 units
After over 40 years with Lamborghini, Balboni is now officially retired. Valentino Balboni continues to travel to many countries around the world as an ambassador of the brand. The special exclusivity of the Lamborghini Gallardo LP550-2 Valentino Balboni is guaranteed - it is limited to 250 units.

The light-footed yet extremely safe
With this latest version of the Gallardo, Lamborghini is honouring its long-standing test driver in a very special way. The Lamborghini Gallardo LP550-2 Valentino Balboni was conceived in line with his own thinking, and it meets many customers' requests for a model with a unique character, which offers a very special kind of active driving fun. The Balboni model is the only current Lamborghini that delivers its power to the road via its rear wheels alone.

The rear wheel drive has a special appeal to those sports car drivers who enjoy a particular driving style. Thanks to the eminently powerful V10 driveline, controlled oversteer is no problem - naturally always to the extent defined by the driver - because refined road manners and perfectly tuned assistance systems mean that the Lamborghini Gallardo LP550-2 Valentino Balboni is an exceptionally safe sports car to drive.

Driving fun with unique character
In order to shape this unique character that combines driving fun and safety, the engineers at Sant'Agata Bolognese have incorporated extensive modifications into the LP550-2 Valentino Balboni. It was not simply a question of moving the transmission to the rear axle, the vehicle had to be adjusted and tuned in every element of its driving dynamics. This includes springs, dampers, stabilisers and even the tyres. The aerodynamics were also adjusted to take account of the change to the power flow.

The rear axle differential, with a 45 percent limited slip, was also redeveloped, as was the calibration of the e-gear transmission. One significant point was the adjustments made to the ESP system. While the standard program is focused on high stability, the CORSA program permits greater drift angles, thus enabling drivers to enjoy the dynamics of the LP550-2 to their full extent.

The outstanding performance is guaranteed
The adjustments have also been made to the very heart of the Lamborghini Gallardo, the 5.2 litre ten-cylinder: the perfect synthesis of hi-revving pleasure, pulling power, a constantly exuberant temperament and a powerful symphony played in all keys. In the Valentino Balboni, the compact and lightweight power unit generates 405 kW (550 hp). At a dry weight of only 1,380 kilograms, this guarantees outstanding performance: the LP550-2 is catapulted from 0 to 100 km/h (0-62mph) in a breathtaking 3.9 seconds, while the top speed of 320 km/h (199 mph) guarantees its place among the ultimate in super sports cars.

The powerful elegance in its distinctive design
The Valentino Balboni is not only unique in terms of its technology: its design and equipment reinforce its exclusivity. Its classic sporting character is emphasised by a colour strip in white and gold running from the front panel over the roof and parts of the engine cover all the way to the rear spoiler, with inspiration from the classic sports cars from the '70s. This colour treatment underscores the powerful elegance of the Lamborghini Gallardo and emphasises the unique Lamborghini design DNA. The Special Edition is available in eight colours, from Bianco Monocerus through to Verde Ithaca, or Arancio Borealis to Nero Noctis. The Scorpius wheels retain their dark grey finish, while the brake callipers come in black, orange or yellow, depending on the exterior paint finish.

The Classic sporting look for the interior.
The characteristic colour combination is repeated in the interior. The basic colour of the full leather upholstery is black. Both seats, however, feature the colour strip in white. The centre console is completely upholstered in Polar white leather to create a powerful accent. A badge below the left side window bears the signature of Valentino Balboni and the production number of the car.
