Chevrolet Corvette Z06

The biggest part of the Corvette story for 2001 is the introduction of the 2001 Corvette Z06, a production vehicle that's ready for the racetrack. Based on the former hardtop model - already the lightest, stiffest and quickest Corvette - it is a car aimed directly at diehard performance enthusiasts at the upper end of the high-performance market. It is very simply the quickest, best handling production Corvette ever, setting new standards in every part of the high-performance spectrum.

The new Z06 takes the term "performance" and raises it to a whole new level. At the heart of the Z06 is a new engine, the LS6, which delivers 385-hp and 385 lb-ft of torque. The LS6 is the only engine available for the Z06, and is not offered on other Corvette models.

The new LS6 is based on the 5.7L LS1, the standard engine in Corvette coupes and convertibles. Its aluminum block has been modified for better management of crankcase pressures and speedier return of oil from the upper part of the engine during high-speed operation. New high-compression cylinder heads (10.5:1 vs. 10.1:1 on the LS1) have improved porting to get this larger volume of air smoothly into the combustion chambers. Exhaust gas backpressure is relieved by Z06's unique, less restrictive titanium exhaust system - the first-ever use of this exotic metal in a mass-production automobile. The new titanium system is 50-percent lighter than the stainless steel system it replaces. The LS-6 engine delivers 385 hp @ 6000 rpm and 385 lb-ft @ 4800 rpm.

Unique to the Z06 is a new 6-speed transmission (M12) with more aggressive gearing to increase torque multiplication in almost every gear and allow for more rapid acceleration. Z06 achieves 0-60 mph in 4 seconds flat, and quarter mile in 12 seconds.
