Porsche GT3 RSR updated for 2009

The venerable 911 continues to succeed in great part because Porsche lavishes so much love and care on it.

McLaren MP4-12 650S hits the Web ahead of official Geneva reveal

Images of the new McLaren MP4-12 650S have leaked to the Internet ahead of a planned unveiling for the British supercar at the Geneva Motor Show in early March. Created in response to customer demand for an edgier version of the McLaren MP4-12C offering greater levels of driver engagement, the 650S runs a more heavily tuned version of McLaren's twin-turbocharged 3.8-liter V8 direct-injection engine producing a claimed 25 hp more than the variant used by standard sibling for a total of 641 hp (as its name suggests 650 ps -- metric hp). Further details remain scarce ahead of the MP4-12C 650S's official public unveiling in Switzerland two weeks from now, although information passed on to prospective customers at a private presentation of the new two-seater held last week suggest it is also in line to receive a series of modifications to its seven-speed dual clutch gearbox, suspension, steering, brakes and aerodynamics -- all aimed at providing it with a more aggressive nature and added racetrack ability.
