From GM Press: The growing Corvette lineup for 2010 includes the Corvette coupe and Corvette convertible, each powered by the 430-horsepower (321 kW) LS3 V-8, and the racing-inspired Corvette Z06. Equipped with the 505-horsepower (377 kW) LS7 engine and built on a lightweight chassis, the Z06 is a street-going descendent of the championship-winning Corvette racing program.
Also available for 2010 is the all-new Grand Sport model, evoking one of the most storied names in Corvette history; and the Corvette ZR1. Equipped with a unique, supercharged LS9 6.2L engine, the ZR1 is the fastest, most powerful car ever offered by Chevrolet. (Please see the separate releases for complete details on the new Grand Sport and the ZR1.)
The Z06 3LZ package now includes power sport seats and power passenger seats.
Launch control optimizes performance for full-throttle starts on a track. In competitive mode, the system will hold a predetermined engine speed while the driver pushes the throttle to the floor. That allows the driver to quickly release the clutch and the system modulates engine torque 100 times per second to maximize the available traction. The system is capable of approaching a skilled driver’s best effort and repeats it consistently.
The 6.2L LS3 small-block V-8 is the standard engine in coupe and convertible models. It is rated at 430 horsepower (321 kW) and 424 lb.-ft. of torque (575 Nm) with the standard exhaust system. An optional two-mode exhaust system brings a power rating increase to 436 horses (325 kW) and 428 lb.-ft. (580 Nm). A standard six-speed manual transmission and an optional six-speed automatic with paddle-shift control are offered.
