Some Key of this Corvette are the Z06 engine, which is powered by a 5.7-liter LS6 V8 engine, producing 405 horsepower & 400 lb-ft of torque. This engine was an upgraded version of the standard LS1 found in other Corvettes of the same era, and the transmission is a 6-speed manual transmission--optimized for performance with a shorter final drive ratio.
The performance of the 2003 Z06 can accelerate from 0 to 60 mph in around 4 seconds, with a top speed of about 170 mph. The C5 was lighter than the standard Corvette, thanks to the use of titanium exhausts, thinner glass, and a fixed roof design.

Inside, the Z06 is equipped with leather seats, a premium sound system, and some lightweight materials to reduce weight. It also features unique Z06 badging.
