The manufacturing company, Pratt and Miller, partnered with General Motors in 1999, bringing about the C5-R Chevrolet Corvette. This Chevy Vette was essentially a C5 with a bigger engine based on the 5700-cc V-8 (the racing versions had 6000 cc’s, eventually increased to 7000 cc’s), a more stream-lined body, wider track, and longer wheelbase.

2003 was a special year for Chevrolet, marking 50 years of Corvette production. To help celebrate, the company introduced a special 50th Anniversary Edition Vette.

The 2009 Chevrolet Corvette ZR1 sports a supercharged, 376 cubic inch, 6.162 L “LS9.” The LS9 is based on the LS3 because higher pressure in the cylinders, as a result of the supercharger, necessitated more substantial cylinder walls, which the previous Corvette LS7 engine did not have.
