The ZR1 is the ultimate expression of Corvette’s technology-driven performance legacy. A supercharged 6.2L LS9 engine and suite of advanced performance technologies, including Performance Traction Management and Magnetic Selective Ride Control, are the elements of the highest-performing Corvette in history, with changes for 2012 designed to make it more comfortable to drive.
Corvette ZR1 is the fastest production model ever offered by General Motors, with a top speed of 205 mph.
Capability of the ZR1 is enhanced for 2012 with the new PDE performance package, which is highlighted by new Michelin® Pilot® Sport Cup Zero Pressure tires. When combined with new-for-2012 Performance Traction Management (PTM) technology – which manages torque delivery for maximum performance – the tires are expected to help set new benchmarks for Corvette performance. Engineers estimate an 8-percent gain in maximum lateral acceleration, to more than 1.1g, and improved braking distance.
The PDE package’s effectiveness was demonstrated with a new lap time of 7:19.63 around Germany’s legendary Nurburgring, which improved on the ZR1’s previous benchmark there by more than six seconds.
Corvette ZR1 also celebrates Chevrolet’s performance heritage with the 2012 Chevrolet Centennial Edition Corvette, which features a sleek black colour scheme, unique design elements and Corvette’s sports car technology. The special package is inspired by Chevrolet’s racing-bred foundation and is offered on all Corvette models for 2012.
Corvette ZR1 for 2012 includes interior improvements shared with all Corvette models, including new seats, a new steering wheel design and a new Bose Premium audio system.

Supercharged LS9 Engine
The LS9 supercharged 6.2L V8 is rated at 638 horsepower (476 kW), and 604 lb.-ft. of torque (819 Nm). The Roots-type supercharger uses a unique, four-lobe rotor design and is augmented with an integrated charge cooling system that reduces inlet air temperature for maximum performance.
Titanium connecting rods.
Cast iron cylinder liners are inserted in the aluminium block and are finish-bored and honed with a deck plate installed. The deck plate simulates the pressure and minute dimensional variances applied to the block when the cylinder heads are installed. The LS9 is hand-assembled at GM’s Performance Build centre in Wixom, Mich., and incorporates special processes typically seen in racing engines to produce a highly refined and precise product.
A six-speed, close-ratio manual transmission is fitted with high-capacity dual-disc clutch, which spreasd 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 rear axle features asymmetrical axle-shaft diameters – 33 mm on the right side and 40 mm on the left – that provide optimal torque management. They are mounted on a more horizontal plane that correlates with the wider width of the ZR1’s rear wheels and tires. Specific suspension tuning provides more than 1g cornering grip.
Twenty-spoke 19-inch front and 20-inch rear wheels are fitted with Michelin Pilot Sport 2 tires – P285/30ZR19 in front and P335/25ZR20 in the rear – developed specifically for the ZR1. Brembo carbon-ceramic, drilled disc brake rotors – 15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear are gripped byblue-painted brake calipers.
Magnetic Selective Ride Control with track-level suspension is standard, including the Launch Control system with Performance Traction Management (PTM) technology which optimises traction for greater and more consistent on-track performance. PTM system holds a predetermined engine speed while the driver pushes the throttle to the floor. That allows the driver to quickly release the clutch and the system modulates engine torque 100 times per second to maximise the available traction. The system is capable of approaching a skilled driver’s best effort and repeats it consistently. PTM also integrates the ZR1’s traction control, active handling and selective ride control systems to enhance track driving consistency and overall performance. When full throttle is applied upon exiting a corner, it automatically manages acceleration dynamics.
Chassis & Suspension
An aluminium body structure for optimum stiffness and light weight for the fixed-roof body style. Perimeter rails are one-piece hydroformed aluminium members featuring cast suspension nodes, which replace many welded steel components on other Corvette models. Advanced structural composites featuring carbon fibre are bonded to the aluminium structure. The wider front wheelhouses, for example, are carbon composites, and the passenger compartment floors combine carbon-fibre skins with an ultra-lightweight balsa wood core.
A magnesium cradle serves as the attachment point for the engine and some front suspension components. It is lighter than aluminium, yet incredibly strong, and helps improve the front-to-rear weight distribution, as do carbon-fibre front fenders and wheelhouses. The battery is relocated from underhood to a position in the rear cargo area, behind one of the rear wheels.
Large wheels, measuring 19 x 10 inches in diameter in the front and 20 x 12 inches in the rear. A Sterling Silver paint finish is standard; chrome and Competition Gray versions are optional. ZR1-specific Michelin Pilot Sport 2 tires measuring P285/30ZR19 in front and P335/25ZR20 in the rear.
Brembo carbon-ceramic brake rotors are made of a carbon-fibre-reinforced ceramic silicon carbide material. These rotors are low mass and resistant to wear and heat. The rotors should never show corrosion or require replacement for the life of the vehicle, when used in normal driving. The vented and cross-drilled rotors on the 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.
Six-piston front calipers and four-piston rear calipers, each painted ZR1-specific blue. A four-channel ABS system is standard, as is a very competent active handling system – complete with a Competitive Driving mode.
Standard 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.
Corvette’s interior is inspired by the car’s dual-cockpit heritage. New seats feature improved appearance and larger bolsters on the seat back and cushion areas to provide better driver support, especially in high-performance driving. Microfibre seat inserts are optional.
The new steering wheel with model-specific badges, streamlined switch trim and wrapped spokes. The ZR1 interior is also adorned with ZR1-logo sill plates and ZR1-logo headrest embroidery.
An AM/FM/XM radio with CD player and audio input jack is standard. A new Bose Premium audio system includes nine speakers (vs. seven in 2011), including new tweeters located in the instrument panel and improve Bose Nd next-generation bass performance. It is included with the 3ZR trim. Steering-wheel mounted audio controls are on all models. SiriusXM Satellite Radio with a one-year subscription is included with the Bose audio system.
An onboard navigation system with voice recognition is included with 3ZR. It is a DVD-based system that uses a 6.5-inch (165 mm) colour touch-screen display.
Head-up display is standard and includes Track Mode with g-meter. A specific gauge cluster with boost gauge (also displayed on the head-up display) and 220-mph (370 km/h) speedometer readout.
A custom leather-wrapped interior package is standard on the 3ZR trim, featuring a leather-wrapped upper and lower instrument panel, door pads and seats; choice of exclusive colours: Dark Titanium, Ebony, Cashmere or Sienna, with unique colour breakup; padded door panel armrests; “Corvette” embroidered on passenger-side dash pad and a unique centre trim plate with a gunmetal pattern.
