Chevrolet Corvette ZR1
The Corvette ZR1 enters its third year of production in 2011. Highlights include an LS9 supercharged 6.2L V-8 rated at 638 horsepower (476 kW), and 604 lb.-ft. of torque (819 Nm); six-speed, close-ratio, race-proven manual transmission; specific suspension tuning provides more than 1g cornering grip; 20-spoke 19-inch front and 20-inch rear wheels; standard Magnetic Selective Ride Control with track-level suspension; Launch Control system with Performance Traction Management technology; wider, a specific gauge cluster with boost gauge (also displayed on the head-up display) and 220-mph (370 km/h) speedometer readout. The ZR1 is the most powerful and fastest automobile ever produced by General Motors. It has a top speed of 205 mph (330 km/h).
The supercharged LS9 6.2L small-block engine is the power behind the ZR1’s performance. A sixth-generation Eaton supercharger helps the LS9 make big power and torque at lower rpm and carries it in a wide arc to 6,600 rpm.
The 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 a visible carbon-fiber-weave. Visible 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 ports; and a full-width, body-color rear spoiler incorporating the center high-mounted stop lamp are also unique to the ZR1. All of the exterior features were developed to enhance high-speed stability and driver control.
