CORVETTE

The ZR1 was formally announced in a December 2007 press statement by General Motors, where it was revealed that their target of 100 bhp (75 kW) per 1 L (61 cu in) has been reached by a new "LS9" engine with an Eaton-supercharged 6.2-liter engine producing a confirmed 638 bhp (476 kW) and 604 lb·ft (819 N·m). It would have a sticker price of about USUS$105,000 with the standard interior or US$115,000 with the leather-wrapped interior. The engine is the most powerful engine to be put into a GM production sports car. Top speed is 205 mph (330 km/h)
In 2010, the historical Grand Sport name returns to the Corvette lineup as an entirely new model series. It combines the wide body from the Z06 with the standard C6 powertrain in both targa coupe and convertible models. With suspension and brake upgrades included, the Grand Sport replaces the Z51 option. A new launch control system was introduced that will allow for more optimal launch in all Corvette models. With launch control, the Grand Sport with a manual transmission is capable of a 0-60 time of four seconds flat.
