The next F1: McLaren plans replacement for supercar

Formula One powerhouse McLaren secretly has begun work on a replacement for its legendary F1 supercar, while it also gears up to become a mainstream sports-car maker. McLaren's Technology Center in Woking, England, has built some 2,000 McLaren SLR supercars a year for Mercedes-Benz, but McLaren boss Ron Dennis reportedly has his sights set on producing 1,000 of its upcoming Ferrari F430-fighting P11s a year starting in 2011. The number, Dennis said, will rise to 4,000 cars by mid-decade as future models such as the Porsche 911-challenging P8 come on line.

2015 Corvette Stingray will get an eight-speed automatic transmission

2015 Corvette Stingray buyers will have a new transmission option when they head to dealer lots next year: An eight-speed automatic that will supposedly weight less than the six-speed it replaces and boasting quicker shift times than the dual-clutch in the Porsche 911. Named the 8L90, this eight-speed will be built in Ohio and will also be found on the upcoming Corvette Z06. If the gearbox is capable of handling the 625 hp put down by that supercharged beast, we're sure it'll take on the regular Stingray's 455 hp without breaking a sweat.
