Chevrolet Corvette ZR1

Chevrolet clearly appear the 2009 Corvette ZR1 - an American supercar that brings the technology and engineering clarification of carbon-fiber, ceramics and electronics calm in a characteristic design.

"Chevrolet's ambition with the fresh ZR1 is to appearance what an American supercar can deliver, at a amount that trumps exotics that amount two, three or four times as abundant - and does so with aberrant driveability," said Ed Peper, Chevrolet accepted manager.

"Preliminary testing shows the ZR1 builds on the awful admired Corvette Z06 in every achievement category, from dispatch and braking, to cornering anchor and top speed," said Peper. "It all boils bottomward to the power-to-weight arrangement and the ZR1's is aberrant - more good than the Porsche 911 GT2, the Ferrari 599 and alike the Lamborghini LP640. In fact, the ZR1 is accepted to be the aboriginal assembly Corvette to accomplish a top acceleration of at atomic 200 mph."

The fresh LS9 6.2L small-block agent is the ability bulb the supports the ZR1's achievement capability. The enabler of the LS9's achievement and clarification is a large, positive-displacement Roots-type supercharger with a new, four-lobe rotor design. It is aggrandized with an chip allegation cooling arrangement that reduces basin air temperature for best performance.

A sixth-generation supercharger developed by Eaton helps the LS9 accomplish big ability and torque at lower rpm and carries it in a advanced arc to 6,600 rpm, as it pushes abundant air to advice the agent advance ability through the high levels of the rpm bandage - the breadth area supercharged achievement tends to diminish. Heavy-duty and failing reciprocating apparatus accredit the engine's assured high-rpm performance.

The LS9 agent is backed by a new, stronger six-speed chiral manual and a twin-disc clamp that accommodate aberrant anchor power, while advancement an accessible clamp effort. ZR1-specific gearing in the manual provides a abrupt first-gear arrangement that helps barrage the car, and top acceleration is accomplished in sixth accessory - a change from the fifth-gear top-speed run-outs in the manual-transmission Corvette and Corvette Z06.
