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.
