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.

Lotus Exige S Roadster Official: Price (£52,800) and Specs

It’s the first properly good news from Lotus for a while, and looks a promising offering at the same price (£52,800) as the tin top Exige S and, remarkably for a convertible, actually weighing less than the hard top – although by only 10kg. The Exige S Roadster gets the same 3.5 litre V6 as the coupe which means 345bhp, 295lb/ft of torque and a 0-60mph of a very respectable 3.8 seconds, but it does lose the coupe’s rear wing and front splitter for better airflow. The folding roof on the Roadster is a manual affair, but Lotus say fresh air motoring is just ‘Two clicks and a roll away’, so the manual roof is probably the best – and lightest – option.
