Caterham – including Caterham F1 – up for sale for £350 million

Will the Caterham AeroSeven Concept (pictured) be a casualty of Caterham’s impending sale? Caterham’s foray in to F1 hasn’t been much of a success, with not a single point on the F1 board since they arrived in 2010 as Lotus Racing (although Marcus Ericsson was just one place off a point at Monaco yesterday). Now, after warning back in January that he would walk away from F1 if the Caterham team’s performance on track didn’t improve, it looks like Fernandes is ready to walk away from Caterham altogether.

SRT Viper

The highly anticipated 2013 SRT Viper was unveiled to the world yesterday at the New York auto show, the third generation of the extrovert supercar. The car's familiar extreme proportions have been retained with its low stance and extreme cab rearward proportions of previous Viper models. The fender 'gills' and double-bubble roof also make a return.

Think City EV Cup Edition (2010) first official pictures

Manufacturers have been trying to make their racers more economical for some time now; Audi and Peugeot have produced diesel Le Mans winners and CAR reviewed the Porsche GT3 R Hybrid in the June 2010 issue, but this the most recent fully electric offering from Norwegian company Think.   Think has followed the traditional road-racer conversion for this one-off prototype, by stripping out most of the interior and space for the passenger, using Perspex instead of glass in the windows, installing a solitary lightweight bucket seat and lowering the centre of gravity. The company claims the diet reduces the Think's weight by nearly 70kg; that's the same saving as a Lamborghini Gallardo Superlegerra, remember.
