Ruf Stormster concept (2009): the electric Porsche Cayenne

Ruf might be a tiny German tuner, but it’s just unveiled the first ever electric Cayenne. Called the Stormster it's Ruf's second battery-powered Porsche, uses the same motor as the company's electric 911, weighs close to 2.7 tonnes and hits 62mph in ten seconds. No at all – in fact, earlier this week Ruf took its 676bhp GT2 to 229mph at the Nardo test track in southern Italy.

The investigation into the Porsche Carrera GT crash that led to the deaths of actor Paul Walker and Roger Rodas has been completed.

Walker and Rodas were killed when their Porsche Carrera GT skidded off the road in a Los Angeles-area business park on Nov.

Concept Car of the Week: DeTomaso Zonda (1971)

Not satisfied in producing one of the most astonishing sports cars of the ‘60s with the Mangusta, Italian carmaker DeTomaso asserted its ambitions in 1970 by presenting an even more striking sports car, the Pantera, alongside the luxurious Deauville four-door sedan, both powered by the same Ford V8 engine. Those new gorgeous models were the work of Dutch-born Tom Tjaarda, then head of design at Ghia. Despite those amazing cars, the styling house was struggling to make a profit and that same year, Alejandro DeTomaso sold Ghia along with a large chunk of his company to Ford, which was looking for that exotic Italian touch.
