Corvette Grand Sport Returns For 2010. In May, Chevrolet announced that the Grand Sport model designation-absent since 1996-will return to the Corvette lineup for the 2010 model year. Combining the Vette's standard LS3-based powertrain with unique, wide-body styling and a race-bred suspension, the 2010 Chevy Corvette Grand Sport is intended to split the difference between the base car and the Z06. It's offered in both coupe and convertible body styles, with either a six-speed manual or a six-speed automatic transmission.
As the replacement for the current Z51 Performance Package, the new 2010 Corvette Grand Sport will come with wider wheels and tires; revised shock, stabilizer bar, and spring specifications; and specific gearing. Manual coupes will also receive a dry-sump oiling system and other track-oriented upgrades. This equipment is said to enable cornering capability of 1.0 g, as well as a 0.2-second improvement in 0-60 acceleration versus standard LS3-powered models.
