The 2012 Corvette ZR1 is the ultimate Corvette - and it's available at your dealer showroom now. Here's a drool-worthy compilation of all the specs to help you with your letter to Santa:
What's So Special About the 2012 Corvette ZR1
The Corvette ZR1 is the fastest, most powerful car ever offered by Chevrolet. The ZR1 is the ultimate expression of Corvette's technology-driven performance legacy, as the fastest production model ever offered by General Motors, with a top speed of 205 mph. Top ZR1 performance was demonstrated with a new lap time of 7:19.63 around Germany's legendary Nürburgring, which improved on the ZR1's previous benchmark there by more than six seconds.
The bottom line on the Corvette ZR1 is that it offers more performance and more technology than the European supercars at a fraction of the price.
638 Horsepower Supercharged LS9 Engine and 6-Speed Transmission
Featuring a unique, supercharged LS9 6.2L engine, the ZR1 delivers 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. Like the legendary 427 cubic inch engines of the past, the ZR1 uses iron cylinder liners inserted in the aluminum block. The LS9 is hand-assembled at GM's Performance Build Center in Wixom, Mich., and incorporates special processes typically seen in racing engines to produce a highly refined and precise product.
The ZR1 engine drives a rear-mounted six-speed, close-ratio manual transmission through a high-capacity dual-disc clutch, 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 rear axle features asymmetrical axle-shaft diameters - 33 mm on the right side and 40 mm on the left to provide optimal torque management.
For a truly intimate and unique experience, customers who opt for the Corvette Engine Build Experience (option code PBC) can participate in the assembly of their engine at the General Motors Performance Build Center in Wixom, Mich.
Corvette ZR1 Suspension and Brakes
The ZR1-specific suspension tuning provides more than 1g cornering grip through the custom twenty-spoke 19-inch front and 20-inch rear wheels wearing Michelin Pilot Sport 2 tires - P285/30ZR19 in front and P335/25ZR20 in the rear. These tires were developed specifically for the ZR1.
Stopping power is provided courtesy of Brembo carbon-ceramic, drilled disc brake rotors and ZR1-unique blue-painted brake calipers. Made of a carbon-fiber-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.
The 2012 Corvette ZR1 also includes Magnetic Selective Ride Control with a track-level suspension, and a Launch Control system with Performance Traction Management (PTM) technology that optimizes traction for greater and more consistent on-track performance. The PTM system holds a predetermined engine speed while you push the throttle to the floor. That allows you to quickly release the clutch and the system modulates engine torque 100 times per second to maximize the available traction. The system is capable of approaching a skilled drag racer's best effort and repeat it consistently. The PTM system 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, the PTM automatically manages acceleration dynamics.
Corvette ZR1 Chassis and Bodywork
Like the Z06, the ZR1 is available only in a fixed-roof body style to optimize body rigidity and mass. You also get extra-wide carbon-fiber front fenders with ZR1-specific dual ports, a carbon-fiber hood with a raised, polycarbonate window offering a view of the intercooler below it. You get a carbon-fiber roof panel, roof bow, front fascia splitter and rocker moldings with clear-coated, visible carbon-fiber weave. Finally, you get the ZR1-specific full-width rear spoiler with raised outboard sections.
The ZR1 perimeter rails are one-piece hydroformed aluminum members featuring cast suspension nodes, which replace many welded steel components on other Corvette models. Advanced structural composites featuring carbon fiber are bonded to the aluminum structure. The wider front wheelhouses, for example, are carbon composites, and the passenger compartment floors combine carbon-fiber 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 aluminum, yet incredibly strong, and helps improve the front-to-rear weight distribution, as do carbon-fiber front fenders and wheelhouses.
2012 Chevy Centennial Edition Corvette ZR1
The following features define the 2012 Corvette ZR1 Centennial Edition:
- Carbon Flash Metallic black paint with satin-black graphics
- Special badges that signify Chevrolet's racing history, including a graphic logo featuring an image of Louis Chevrolet on the B-pillars, the wheel center caps and the center of the steering wheel.
- The historic Corvette crossed flags badge contains a small adaptation, with "100" in place of the traditional fleur-de-lis symbol, only for the Centennial Edition.
- Unique Centennial Satin Black wheels, sized specifically to the respective Corvette models, including 18-inch/19-inch for Coupe, Convertible and Grand Sport; and 19-inch/20-inch for Z06 and ZR1.
- Red brake calipers.
- Magnetic Selective Ride Control is standard.
- Ebony leather-wrapped instrument panel and doors complimented by red stitching also on the steering wheel, seats, console and shifter.
- The seats feature microfiber suede accents on seats, steering wheel, shifter and armrests, which were first used on the 2011 Z06 Carbon Limited Edition.
- Seat headrests carry an embossed centennial logo.
- Available on all Corvette models via order code ZLC.
