Chevrolet Corvette Z06

Model year 2006 will always be known as the year the 505-horsepower Z06 was let loose on the sports car world. With its 505-horsepower (377 kw) LS7 7.0L engine, racing-bred suspension, hydroformed aluminum frame and unique bodywork, the Z06 is the fastest, most technologically advanced production model in Corvette’s 53-year history.

The Z06’s new LS7 7.0L engines delivers 505 horsepower (377 kw) in an approximately 3,130-pound (1,420 kg) package – a combination that delivers 0-60 performance of 3.7 seconds in first gear, quarter-mile times of 11.7 seconds at 125 mph and a top speed of 198 mph (as recorded on Germany’s Autobahn). It also provides maximum lateral acceleration of 1.04 g and 60-0 braking in 111.3 feet; it also circuited Germany ’s famed N ü rburgring in a time of 7:43 . Along with astounding performance, Corvette Z06 also returns surprising fuel economy of 26 mpg on the highway.

The all-new LS7 in the ’06 Z06 reintroduces the 427-cubic-inch engine to the Corvette lineup. Unlike the previous 427 engine, which was a big-block design, the new 7.0-liter LS7 is a small-block V-8 – the largest-displacement small-block ever produced by Chevrolet and GM, and a tribute to its 50 years as a performance icon.

With 505 horsepower (377 kw) and 470 lb.-ft. of torque (637 Nm), it also is the most powerful passenger car engine ever produced by Chevrolet and GM. The LS7 is easily identified under the hood by red engine covers with black lettering. The LS7 shares the same basic Gen IV V-8 architecture as the Corvette’s 6.0-liter LS2, but it uses a different cylinder block casting with pressed-in steel cylinder liners to accommodate the engine’s wide, 104.8-mm-wide cylinder bores. Compared with the LS2, the LS7 also has a different front cover, oil pan, exhaust manifolds and cylinder heads – among many other components.
