Chevrolet Corvette (C6)
This article is about the sixth generation Chevrolet Corvette (C6). For general Corvette information, see Chevrolet Corvette. The Corvette C6 was virtually all new including new bodywork with exposed headlamps, an overhaul of the suspension geometry, a larger passenger compartment, a larger 6.0 L engine and a much higher level of refinement.
New, Supercharged LS9 V-8 is the Heart of the ZR1
Chevrolet goal with the new 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.
Supercharged LS9 engine
The new LS9 6.2L small-block engine is the power plant the supports the ZR1’s performance capability. The enabler of the LS9’s performance and refinement is a large, positive-displacement Roots-type supercharger with a new, four-lobe rotor design.
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.
Ride and handling
The 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 ZR1 differs is the suspension tuning, which was optimized for the car’s steamroller-wide front and rear tires.
Brakes, wheels and tires
The brakes are visible through the 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 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 “base” ZR1 comes with accoutrements based on the Z06, including lightweight seats and lightweight content. The uplevel interior package includes unique, power-adjustable and leather trimmed sport seats; custom, leather-wrapped interior available in four colors; navigation system, Bluetooth connectivity and more.
