GENEVA, Switzerland - Chevrolet has presented its most track-capable Corvette yet, the Z06, at the 2015 Geneva auto show.

The all new Corvette is the most powerful production car yet from General Motors, the company says, with more than 445kW. With the available Z07 package, the supercar accelerates from 0-100km in 3.4sec with the eight-speed automatic and in 3.8 with the seven-speed manual transmission.

To balance performance and efficiency, the Z06 uses the same trio of advanced technologies introduced on the Corvette Stingray – direct injection, cylinder deactivation and continuously variable valve timing – and feeds it all wth a new and more efficient supercharger.


President and MD of Chevrolet and Cadillac Europe, Thomas Sedran, said: "The new Corvette Z06's performance and technical capabilities makes it one of today's most desirable supercars.

"It is the first Z06 to offer an eight-speed paddle-shift auto transmission and, thanks to a stronger aluminIum frame, a removable roof panel. In addition, it is the first time since 1963 that the Z06 is available as a convertible."

The heart of the 2015 Corvette Z06 is an all-new LT4 6.2L supercharged V8 engine delivering an SAE-certified 485kW/881Nm.


To maintain the Z06’s mass and performance targets, the LT4 engine was designed with a more efficient, more compact, supercharger. Even with its integrated supercharger/intercooler assembly mounted in the V between the cylinder heads, the engine is only about 25mm taller than the Corvette Stingray’s LT1 engine – while delivering nearly 37% more power and 40% more torque, the developers said.

The new supercharger spins at up to 20 000rpm – 5000rpm more than the supercharger on the Corvette ZR1’s engine. The rotors are of smaller diameter, which contributes to their higher-rpm capability – and enables them to produce power-enhancing boost earlier in the rpm band.

That boost is achieved more efficiently through a more direct discharge port that creates less turbulence, reducing heat and speeding airflow into the engine.
