Dodge Zeo, Ram (2008): first official pictures

By James Foxall First Official Pictures 14 January 2008 19:43 Dodge has got a long way to go if it’s to convince people it’s really concerned about the environment. The car the American firm was really trumpeting at Detroit was a concept muscle car called the Zeo. A lithium ion battery powered lightweight car that will do 0-60mph in 5.7 seconds and has an equivalent power output to 286bhp sounds impressive – until you see it’s only got a range of 250 miles.

Sir Stirling Moss, 81, retires from racing

While participating in a live interview with Joe Bradley of RadioLeMans.com on Thursday, Sir Stirling Moss announced his retirement from the sport that he loves. "This afternoon I scared myself, and I have always said that if I felt I was not up to it or that I was getting in the way of fellow competitors, then I would retire," Moss said. Moss is one of the most recognizable figures in motorsports, with a career that has spanned more than 60 years.

The next McLaren supercar will be called the 650S

We've known that McLaren has a pair of additional models in the works, including a Porsche 911-fighting, 12C-based sports car known only as the P13 and another car positioned between the 12C and the P1. Previously, we'd heard the code name “P15” tossed around in reference to that latter car, but McLaren has officially christened it the 650S ahead of its world debut at the upcoming Geneva motor show. According to the automaker, the 650S “takes learnings from both the 12C as well as the sell-out McLaren P1 [ed note: there has to be a better way to say that] and will be positioned between the two on McLaren Automotive's supercar grid.“ We liked the 12C, and we really, really liked the P1.
