The New Audi Q7 V12 TDI

For two decades Audi has driven forward the advancement of diesel technology – from the very top. Now the brand with the four rings is presenting another world first: the first V12 TDI in a passenger vehicle. The diesel, which generates an output of 368 kW (500 hp) and 1,000 Nm of torque (737.56 lb-ft) from a capacity of six liters, gives the new Audi Q7 V12 TDI quattro the performance of a sports car. It catapults from zero to 100 km/h (62.14 mph) in only 5.5 seconds and has an electronically capped top speed of 250 km/h (155.34 mph). The V12 diesel is opening up entirely new horizons in the diesel sector. The big-performance SUV from Audi completes all intermediate sprints with fascinating ease; in every driving situation it boasts superior reserves of power. The engine captivates its drivers not only with its sheer inexhaustible power but also with its highly cultivated manner of operation – the subtle engine sound takes on a voluminous, strong note when the throttle is open. In terms of fuel consumption the six-liter TDI, which features a completely redeveloped common rail injection system, requires an average of only 11.3 liters/100 km (20.82 US mpg), substantially less than the gasoline units produced by the competition. No competitor is able to match this achievement.

2,000 bar: common rail technology with a new level of performance

The two twin-plunger high-pressure pumps have been completely redeveloped. They can create pressures as high as 2,000 bar in the rails – up to now 1,800 bar was the norm. The piezo injectors with their eight-hole nozzles, each with a diameter measuring only 0.12 millimeters (0.005 inch), have also undergone a fundamental reworking. The high pressure creates an extremely precise spray pattern in the combustion chambers that permits a faster, more homogeneous and therefore more acoustically refined ignition process. The highly efficient combustion process also increases power output, cuts consumption and reduces pollutant emissions.

The current generation of so-called inline injectors utilizes the piezo effect: piezo crystals expand in a fraction of a millisecond when an electrical voltage is applied. Over 300 piezo disks are packed into the V12 TDI injectors, which use the expansion to initiate the injection process directly. Each actuation takes just a few milliseconds – at 100 milliseconds, the wink of an eye lasts much longer.

The number of injection processes per operating cycle can be varied across a wide range thanks to piezo technology – reaching as many as five fuel injection operations. One to two pilot injections ensure smooth engine operation in all load and speed ranges. Delayed post-injection serves to increase the temperature of the exhaust gas in order to regenerate the two particulate filters included as standard.

The two turbochargers are located on the outside of the engine’s vee, each of them supplying one bank of cylinders. Thanks to their variable vane geometry the full exhaust flow is directed through the turbines at all times – the turbochargers respond even at low engine speeds and achieve a high level of efficiency.

2.7 bar: high boost pressure

Both turbocharges generate up to 2.7 bar of absolute boost pressure. Two large intercoolers reduce the temperature of the compressed air and thus increase the level of oxygen required for combustion. The V12 TDI features a dual-branch intake system. For each bank of cylinders there is an air filter, behind which an air mass meter is located.

Two ultra-fast control units manage events in the engine, sharing the workload according to a master/slave principle. The six-liter has adopted map-controlled swirl variation of the combustion air from its smaller TDI siblings. The electrically controlled flaps can be adjusted to ensure optimum swirl with respect to high performance and low emissions.

The exhaust system also has a dual-branch design; here Audi engineers focused their attention on exhaust gas recirculation. At partial throttle, up to 50 percent of the exhaust is fed back into the intake air in order to reduce NOx emissions. The large-dimension recirculation system, located at the top of the inner vee, incorporates a water cooler that uses map-based control to lower the temperature of the exhaust gas.

With its 368 kW (500 hp) the diesel generates a specific power output of 62.0 kW (84.3 hp) per liter of capacity – worthy of a sports car. Even more impressive is its maximum torque: between 1,750 rpm and 3,250 rpm the V12 TDI has a constant 1,000 Nm (737.56 lb-ft) on tap – this amounts to 168 Nm (123.91 lb-ft) per liter of capacity. The 11.3 liters of fuel that the potent TDI requires on average per 100 km (20.82 US mpg) is a reflection of its superior efficiency. This figure is even more astounding when compared with gasoline engines offered by the competition – the fuel consumption of these units is much higher all-round.

The transmission

The mighty engine power of the V12 TDI flows through a fast and extremely smooth-shifting six-speed tiptronic, which was specially designed for the immense torque of the six-liter diesel. The driver can shift the gears of the automatic transmission either manually with the selector lever or with the standard chromed shift paddles on the three-spoke leather-covered steering wheel.

The quattro drive distributes the power to the front and back wheels in a 40:60 ratio – giving the vehicle a sporty, rear-focused driving style that guarantees maximum agility and driving enjoyment. When needed, the inter-axle differential transfers most of the power to the axle with better traction. Great care has also been devoted to reinforcing all key components in the quattro driveline.

The chassis

The chassis of the Audi Q7 V12 TDI quattro is a marvel of high-tech construction. Double wishbones guide the front and rear wheels; the axle components are made primarily of aluminum. Thanks to the extreme precision and directness of the servotronic steering, the driver remains in close contact with the road. This is where the handling characteristics, driving safety and comfort of the performance SUV set the benchmark.

Even in rough terrain the Audi Q7 V12 TDI quattro can easily cope with the challenges – with a maximum ground clearance of 240 millimeters (9.45 inches). The ESP stabilization system features hill descent assist and a special off-road mode which optimizes traction.

The standard adaptive air suspension works with sporty new tuning. In combination with electronically controlled shock absorbers incorporating dynamic roll stabilization, the air suspension can be adjusted in three zones ranging from extremely comfortable to highly dynamic. The driver can also adjust ground clearance in five stages via this system and lower the tail end by 71 millimeters (2.80 inches) for comfortable loading.

The ultimate performance SUV from Audi is fitted with sporty 20-inch cast aluminum wheels with a ten-spoke design. Alternatively, wheels with a 20-spoke design are available, as are impressive 21-inch wheels in a choice of three different designs.

Behind the large wheels is a powerful 20-inch brake system. Made of ceramic reinforced with carbon fiber, the internally ventilated disks are notable for their low weight, robust performance and minimum wear. As on a high-performance sports car, eight-piston calipers grip the disks at the front axle, while the rear brakes each have four pistons. The calipers are painted in Titanium Gray – the front ones bear the lettering “Audi ceramic”.

The design

The visual styling of the Audi Q7 V12 TDI quattro gives the vehicle an unmistakable look. Daytime running lights consisting of twelve white LEDs per headlight announce the vehicle’s presence even at a distance. They are located on the upper edge of the air intake slots, replacing the turn signals that were moved to the bi-xenon headlights. Further honing the vehicle’s profile are vertical chromed bars in the grid of the single-frame radiator grill and an underbody protector made of stainless steel. The newly designed bumper groups the highly polished side air intake slots into large units.

When viewed from the side, both the 20-inch wheels and the matt aluminum caps on the exterior mirrors catch the eye. The wheel arches have been widened a total of 26 millimeters (1.02 inches) at the front and 30 millimeters (1.18 inches) at the rear; the lower edges of the doors flaunt striking new moldings. The windows are framed by matt aluminum cover strips; the roof rails sport the same look. The taillights are set in a dark-colored background, while the newly designed bumper incorporates two large, oval exhaust tailpipes. At the rear, the underbody protector is also made from stainless steel. A metallic or pearl effect finish comes as standard.

The Audi Q7 V12 TDI quattro impresses with its elegant and dynamic styling. The ultimate performance SUV from Audi has a powerful and elongated look; with a length of 5,063 millimeters (199.33 inches), a width of 2,000 millimeters (78.74 inches) and a height of 1,737 millimeters (68.39 inches) it boasts the sportiest dimensions in its class.

High side panels lend the vehicle body a muscular appearance, particularly in contrast with the flat, sporty window area. The dynamic line above the wheel arches, the powerful shoulder section and the flowing roof line together with the standard roof rails underline the vehicle’s athletic looks. The pronounced tapering of the front section and the rear end with its sharply sloping D-posts fashion a coupe-like silhouette.

The interior and the cockpit area create a sense of light and airy spaciousness, perfect ergonomics and excellent quality. Audi offers customers a choice of four, five, six or seven highly versatile seats. Depending on seating capacity, the cargo area can hold up to 2,035 liters (71.87 cubic feet).

Aluminum inlays shine in the door sill trims and the carpet is made of velour. Carbon fiber covers and the aluminum-look selector lever give the center tunnel a high-tech ambience, exclusive wood trim is available as an option. The buttons of the MMI operating system, which has proven a superior concept in numerous independent tests, gleam in silver, the air vents in aluminum, the pedals and footrest in stainless steel.

Verano leather covers the electrically adjustable sport seats; the deluxe center armrest and the armrests in the doors are upholstered with leather as well. The front and rear seats can be heated; a special lighting package softly illuminates the interior.

The equipment

Also included in the luxurious standard specification for the Audi Q7 V12 TDI quattro are the leather package, leather multifunction sports steering wheel, black roof lining, folding exterior mirrors, DVD navigation system, Bose Surround Sound system with CD changer, Bluetooth mobile phone preparation, alarm system and tire pressure monitoring system.

The tailgate opens and closes electrically – it partly overlaps the D-posts, lending a muscular look to the rear end. The standard deluxe automatic air conditioning regulates heating and ventilation separately for the driver’s and front passenger’s side, taking sunlight levels into account at the same time.

Audi offers four optional high-tech assistance systems for the Audi Q7 V12 TDI quattro: adaptive cruise control, Audi lane assist and Audi side assist help the driver to maintain the correct distance from the vehicle in front, stay in lane and change lanes. Audi parking system advanced includes a camera to monitor the area behind the vehicle.

The multimedia system becomes even more versatile with the optional Audi music interface, a convenient connection point for the customer’s iPod. Available on request is the Advanced Sound System from Bang & Olufsen, which offers a totally unparalleled sound experience.

The leather package advanced offers even more comfort in the interior, and includes exclusive coverings for the dashboard and centre console. The large glass sunroof – the open sky system – and a rail system for the cargo area further enhance the appeal of the Audi Q7 V12 TDI quattro as a touring vehicle.

The Audi Q7 V12 TDI quattro, the exclusive top model in the series, makes its way to dealers towards the end of 2008.

The New Volkswagen Golf

Volkswagen is sending a new Golf out into the world, the best of all times. The Volkswagen Golf is a phenomenon, regardless of its particular generation. Positioned in the compact class, this style icon defies all automotive and social class distinctions. No other car in this price segment has even come close to reaching as large a cross-section of people. The Volkswagen Golf is the only one that always fits right, and the new one is even better fitting.

It was perfected in every detail. It is also the quest for perfection that has elevated the styling of the Volkswagen Golf to a new level. The team headed up by the Group’s chief designer, the Italian Walter de Silva, has succeeded in giving the Volkswagen Golf a presence, a sharpness, a power that generates even more fun. Fun to look at and fun to drive. An intelligent car. Data such as an average fuel consumption of 4.5 liters per 100 kilometers for a 110 PS TDI put fuel prices in their place. Upon request, the VW Golf can park itself nearly automatically in the city thanks to “Park Assist”, it can maintain an ideal gap on the freeway by distance control (ACC), and at the push of a button it can transform itself from a cruiser to a sports car when the new “DCC Adaptive Chassis Control” system is on board.

Above all, the car exhibits a standard of quality never before attained in this price class. Prof. Dr. Martin Winterkorn, Chairman of the Board at Volkswagen AG sums it up: “This sixth generation of Volkswagen Golf cars will completely redefine the quality and comfort level of its class over broad categories, offering more customer value than ever before”. In Europe the new Volkswagen Golf will be introduced to the market in October. Following in succession will be Africa, Asia, Australia and North America.

Low-noise comfort – the quietest Volkswagen Golf since the model series began

The new VW Golf is characterized by first-class acoustic properties. A special sound-damping film in the windshield reduces driving noises, as does the newly developed seal design on the doors and side window guides. Significantly less wind noise is generated by the outside mirrors due to their new shape. Furthermore, special modifications were made to better isolate the engine and passenger compartments from one another acoustically. Quiet rolling tires and new engine bearings round out the noise reduction program.

Diesel engines – the shift to common rail injection

Making a significant contribution to the pioneering acoustic properties of the Volkswagen Golf are the exceptionally quiet common rail TDI engines being implemented on the Volkswagen Golf for the first time. Two balancer shafts (from 103 kW / 140 PS) also eliminate undesirable vibrations. Plans call for a TDI power range from 66 kW / 90 PS to 125 kW / 170 PS. Right at its market launch Volkswagen will be offering two 2.0 liter TDI engines on the Volkswagen Golf; they deliver 81 kW / 110 PS and 103 kW / 140 PS. Always there: a diesel particulate filter (DPF).

The new TDIs are exceptionally fuel efficient. The 110 PS strong diesel is satisfied with just 4.5 liters of fuel per 100 kilometers (119 g/km CO2) – that represents a 0.6 liter reduction in fuel consumption! Even the 140-PS version only requires 4.9 liters of diesel (129 g/km CO2), which is 0.6 liter less than the on the previous generation.

Gasoline engines – more fuel efficient than ever before

In the launch phase, four variants will define the range of gasoline engines with 59 kW / 80 PS, 75 kW / 102 PS, 90 kW / 122 PS and 118 kW / 160 PS. Starting at 90 kW / 122 PS, TSI engines with supercharging and/or turbocharging are used. The fact is: the gasoline engines are also pioneers in economy. The optimized 80-PS entry-level engine consumes just 6.4 liters Super per hundred kilometers (149 g/km CO2) – that is 0.5 liter less than its predecessor. The TSI engines once again make their appearance as prime examples of efficiency: with 122 PS the new Golf 1.4 TSI consumes just 6.2 liters Super (144 g/km CO2); this represents a fuel consumption advantage of 0.1 liters. Even the new 160-PS top version of the 1.4 TSI achieves a top value at 6.3 liters. The 160-PS TSI’s fuel consumption too was lowered by 1.6 liters compared to the retired 150-PS FSI.

DSG – replaces conventional automatic

With the exception of the entry-level versions, all gasoline and diesel engines may be paired with Volkswagen’s dual clutch transmission (DSG). Either a 6-speed or 7-speed DSG is used, depending on engine torque. This means that on the VW Golf the extremely efficient and agile DSG has replaced the classic torque converter automatic. Just how economical the alliance of TSI plus DSG can be is demonstrated by the example of average fuel consumption on the 1.4 TSI with 160 PS and 7-speed DSG: 6.0 liters (139 g/km CO2). This high-tech duo replaces the 2.0 FSI with 150 PS and 6-speed automatic. Average fuel consumption there: 8.3 liters. Savings: 2.3 liters per hundred kilometers or 28 percent – progress at its best.

The New Renault Twingo RS

Sports styling inside

The ergonomic driving position conjures the world of racing with features that are centred firmly on the driver: aluminium pedals, and a four-spoke perforated leather steering wheel with dark charcoal stitching and a stitched red marker at the straight ahead point. Not only does this design offer increased comfort, it allows the driver a perfect grip in the 'ten-to-two' position. The rev-counter is located directly behind the steeringwheel, echoing racing car design. Employing a specific typeface, the numbers grow in size as the needle approaches the red line at 7,000rpm. Just like in the cockpit of the ING Renault F1 Team's R28 Formula 1 car, the rev-counter features a gear change alert to warn the driver as the engine approaches maximum revs.

The dark charcoal interior trim neatly expresses sporting performance. Offering additional lateral support and with excellent levels of comfort, the specific Renault Sport seats allow the driver to feel at one with the car. The colour of the Blood Orange safety belts matches the contrasting stitching on the upholstery. As with all cars developed by Renault Sport Technologies, the Renault Sport logo can be found inside the cabin, on the rev-counter, the door sills and the front seats. Outside, the badge features on the rear hatch and engine air filter.

A composed, balanced platform

Just like all other models in the Renault Sport range, the newcomer offers two chassis options: sports and Cup. On both, track has been widened by 60 mm at the front and 59 mm at the rear compared to Twingo GT. These modifications improve stability and lateral grip.

The front suspension is a pseudo-MacPherson type arrangement, with aluminium lower arms. The adoption of pushrods on the dampers improves the performance of the anti-roll bar for even better body control.

Renault Twingo RS's suspension is based on an H-type programmed deflection rear beam. To improve ride and comfort, the dampers are mounted vertically and coupled with variable rate coil springs. The 24mm diameter rear anti-roll bar (compared to 22.5mm on Twingo GT) brings a stiffness gain of 25%. The anti-roll performance has been calibrated to improve rear-end agility.

The set-up of the sport chassis was honed for the best and safest balance between driving enjoyment and performance. Compared to Renault Twingo GT, the chassis features a lower centre of gravity, thanks to a 10mm lower ride height. Stiffer springs (+30% compared to Twingo GT) and uprated dampers (also +30%) add to the car's sporty handling, while firmer bushing has enhanced suspension performance front and rear. The Renault Twingo RS sport chassis is also fitted with generously-proportioned tyres (195/45 R16).

A performance-focused Cup chassis

Renault Twingo RS is also available with a Cup chassis for incisive handling and maximum driving enjoyment. In this configuration, Renault Twingo RS offers handling to satisfy the demands of any enthusiast. This chassis offers optimum body control and its natural home is on the track, where flat cornering and improved corner speed demonstrate its effectiveness.

The Cup chassis rides another 4mm lower than the sport version, and its lower centre of gravity improves in-corner performance thanks to reduced weight transfer. Tuned damper settings and higher spring rates (10% stiffer front and rear) bring greater performance through better body control.

Outside, the Twingo Renault Sport Cup chassis stands out by its Dark Metal Grey 17-inch aluminium alloy wheels.

A punchy, flexible engine

Renault Twingo RS is powered by a normally-aspirated 1.6-litre 16V engine (K4M RS) which delivers 133hp (98kW) at 6,750rpm and 160Nm of torque at 4,400rpm. The free-revving engine offers flexible performance and instantaneous throttle response. At low revs and in the mid-range below 4,500 rpm, Renault Twingo RS offers lively, easy performance for everyday use. Beyond 4,500rpm, Renault Twingo RS gives full vent to its sporting character with true punchy performance.

The 133hp 1.6 litre 16V engine has been developed from the 1,598cc petrol engine. The improved power and torque are the result of a number of modifications and improvements to the mechanical components:

• The air filling rate has been improved thanks to a specific throttle valve unit and aluminium plenum chamber, plus revised diameters and lengths for the air-inlets.
• To improve air intake and facilitate gas flow, research was carried out on the aerodynamics of the valve seats. The calibration of the camshafts was revised to a longer opening of the valves and higher lift (11mm compared to an average of 9mm).
• The design of the combustion chamber and piston enables a high compression ratio of 11.0:1, leading to enhanced combustion and efficiency and reduced harmful emissions.
• The continuously-variable inlet camshaft improves performance right across the rev range. The actuator varies the timing setting to optimise valve opening and closing.

Sports performance and acoustic enjoyment

The experts at Renault Sport Technologies have worked hard to give the Renault Twingo RS an engine note in keeping with its sporting character. The engine noise is minimal at low revs, but builds mid-way through the rev range to become 'fiery' when pushed to its limits.

The four-into-one exhaust manifold, made from thin-walled steel, forms the object of a patent by Renault Sport Technologies. The technological marvel is to have combined four long steel tubes in such a restricted space. This architecture offers an excellent trade-off between acoustics, performance and emissions. Indeed, the engine has been designed to be able to comply with Euro5 legislation.

Renault Twingo RS is fitted with a revised version of the five-speed manual gearbox (JR5). The closely-spaced ratios are linked to a fast and precise shift mechanism to favour crisp acceleration in all gears.

The Renault Sport Technologies entry-level model

Renault Twingo RS is the latest model in the Renault Sport Technologies range, and will reach market late in the third quarter of 2008 in Western Europe. This latest example of Renault's hot hatch prowess rounds off the Renault Sport family alongside Clio and Mégane Renault Sport.

With nearly 13,000 registrations in 40 countries in 2007, the Renault Sport range registered an increase in volume of more than 50% compared to 2006. The arrival of the new Renault Twingo RS will help the Group expand its presence even further in the hot hatch market. Great Britain is the number one market for Renault Sport vehicles, and should account for a third of sales. France, Spain, Italy, Germany and Switzerland are expected to share approximately 55% of registrations.

The New Chevrolet Corvette ZR1

Chevrolet officially announced the 2009 Chevrolet Corvette ZR1 - an American supercar that brings the technology and engineering refinement of carbon-fiber, ceramics and electronics together in a distinctive design.

"Chevrolet's goal with the new Chevrolet Corvette ZR1 is to show what an American supercar can deliver, at a price that trumps exotics that cost two, three or four times as much - and does so with exceptional driveability," said Ed Peper, Chevrolet general manager.

The Chevrolet Corvette ZR1's basic stats:

• All-new LS9 supercharged 6.2L V-8 targeted at producing at least 100 horsepower per liter, or 620 horsepower (462 kW), and approximately 595 lb.-ft. of torque (823 Nm)
• Six-speed, close-ratio, race-hardened manual transmission
• New, high-capacity dual-disc clutch
• Higher-capacity and specific-diameter axle half-shafts; enhanced torque tube
• Specific suspension tuning provides more than 1g cornering grip
• Twenty-spoke 19-inch front and 20-inch rear wheels
• Michelin Pilot Sport 2 tires - P285/30ZR19 in front and P335/25ZR20 in the rear - developed specifically for the Chevrolet Corvette ZR1
• Standard carbon-ceramic, drilled disc brake rotors - 15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear
• Larger brake calipers with substantially increased pad area
• Standard Magnetic Selective Ride Control with track-level suspension
• Wider, carbon-fiber front fenders with Chevrolet Corvette ZR1-specific dual vents
• Carbon-fiber hood with a raised, polycarbonate window - offering a view of the intercooler below it
• Carbon-fiber roof panel, roof bow, front fascia splitter and rocker moldings with clear-coated, exposed carbon-fiber weave
• ZR1-specific full-width rear spoiler with raised outboard sections
• Specific gauge cluster with boost gauge (also displayed on the head-up display) and 220-mph (370 km/h) speedometer readout
• Only two options: chrome wheels and a "luxury" package
• Curb weight of approximately 3,350 pounds (1,519 kg)

Transmission and axle

The LS9 engine is backed by a new, stronger six-speed manual transmission and a twin-disc clutch that provide exceptional clamping power, while maintaining an easy clutch effort. Chevrolet Corvette ZR1-specific gearing in the transmission provides a steep first-gear ratio that helps launch the car, and top speed is achieved in sixth gear - a change from the fifth-gear top-speed run-outs in the manual-transmission Corvette and Corvette Z06.

As the term implies, the twin-disc clutch system employs a pair of discs, which spreads out the engine's torque load over a wider area. This enables tremendous clamping power when the clutch is engaged, while also helping to dissipate heat better and extend the life of the clutch.

The twin-disc clutch system also contributes to the Chevrolet Corvette ZR1's exceptional driving quality, with smooth and easy shifting. The twin-disc system's design enables a 25-percent reduction in inertia, thanks to smaller, 260-mm plates, corresponding to a pedal effort that is similar to the Corvette Z06's 290-mm single-disc system.

The rear axle also is stronger in the Chevrolet Corvette ZR1 and features asymmetrical axle-shaft diameters that were developed after careful testing to provide optimal torque management. The axles are also mounted on a more horizontal plane that correlates with the wider width of the rear wheels and tires.

Ride and handling

The Chevrolet Corvette ZR1 is built on the same aluminum-intensive chassis as the Corvette Z06 and features similar independent SLA front and rear suspensions, with aluminum upper and lower control arms. Where the Chevrolet Corvette ZR1 differs is the suspension tuning, which was optimized for the car's steamroller-wide front and rear tires.

Magnetic Selective Ride Control is standard and tuned specifically for the Chevrolet Corvette ZR1. The system's ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.

From a high-performance perspective, Magnetic Selective Ride Control helps the rear axle remain planted during launch for smooth, hop-free acceleration. It also helps suppress axle movement when cornering on broken or uneven pavement.

Brakes, wheels and tires

Commensurate with the Chevrolet Corvette ZR1's engine output is the braking system, which is headlined by carbon-ceramic brake rotors. Found on only a few exotics and more expensive supercars, carbon-ceramic brake rotors are made of a carbon-fiber-reinforced ceramic silicon carbide material . Their advantage comes in low mass and resistance to wear and heat. In fact, the rotors should never show any corrosion or require replacement for the life of the vehicle, when used in normal driving.

The vented and cross-drilled rotors on the Chevrolet Corvette ZR1 measure 15.5 inches (394 mm) in diameter in the front and 15 inches (380 mm) in diameter in the rear - making them among the largest carbon-ceramic rotors available on any production vehicle.

Clamping down on the high-tech rotors are six-piston front calipers and four-piston rear calipers, each painted a Chevrolet Corvette ZR1-exclusive blue. The front pads are equivalent in size to the largest on any production car with a single-pad design - double that of the Corvette Z06's 70-sq.-cm. front pads.

The brakes are visible through the Chevrolet Corvette ZR1's exclusive wheels: 20-spoke alloy rims that measure 19 inches in diameter in the front and 20 inches in the rear. They come standard with a bright, Sterling Silver paint finish and chrome versions are optional. The wheels are wrapped in Michelin Pilot Sport 2 tires developed specifically for the Chevrolet Corvette ZR1, measuring P285/30ZR19 in front and P335/25ZR20 in the rear.

Exclusive exterior

The Chevrolet Corvette ZR1 is instantly recognizable, with perhaps the most identifiable feature a raised, all-carbon-fiber hood that incorporates a clear, polycarbonate window. The window provides a view of the top of the engine's intercooler, with the legend "LS9 SUPERCHARGED" embossed on the left and right sides, and an engine cover with the Corvette crossed flags logo debossed at the front.

The underside of the hood has an exposed carbon-fiber-weave. Exposed carbon-fiber is used on the roof, roof bow, rocker molding and front splitter. These exterior components are protected by a specially developed glossy, UV-resistant clear coat that resists yellowing and wear.

Widened, carbon-fiber front fenders with specific, dual lower vents, and a full-width, body-color rear spoiler incorporating the center high-mounted stop lamp, are also unique to the Chevrolet Corvette ZR1. All of the exterior features of the car were developed to enhance high-speed stability and driver control.
