The Chevrolet Corvette Z06 CSR, or Competition Sport Package, was a limited edition variant of the C6 Corvette Z06 that was available for the 2009 model year. The CSR was offered in black or silver paint with unique decals. These cars were powered by a 7.0L V8 engine that generated 505hp which was sent to the rear wheels via a 6 speed manual gearbox. A rare offering, the Z06 CSR saw just 20 examples built, 10 in black, and 10 in silver.
