2015 Ford Mustang Mach 1 rendered

File this one under "harmless speculation we're hoping Ford execs are paying attention to": Top Speed has rendered the 2015 Mustang Mach 1, giving an idea of what to expect if/when the Blue Oval trots out a hotter version of the newest pony car. The heat extractors on the hood get beefed up, and there's no missing the gigantic, adjustable front splitter. The lip spoiler on the trunk would be subtle if not for the contrasting black paint.

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.
