Audi A1 Quattro (2012) first official pictures

This is the Audi A1 Quattro, a 252bhp and four-wheel drive hot hatch that’s as exclusive as an R8 GT Spyder. Just 333 Audi A1 Quattros will ever be built so they’ll be a rare sight on the road – and particularly in Britain as the entire production run is left-hand drive, and Audi UK will import a tiny number only if there’s enough customer interest. So I probably can’t afford an Audi A1 Quattro, and I might never see one – what am I missing out on?

This year marked the 60th anniversary of the Corvette, and Chevrolet marked the occasion in style by launching an all-new model back in January 2013 – the seventh generation of the 'Vette.

Best of all though is the news that the road racer will reach UK dealerships next autumn, priced from £61,495.

Tesla system will swap a Model S battery in 90 seconds

"This is the title fight," said Elon Musk, in typical brashness. "This is battery-powered versus gasoline." The Tesla CEO preached this to a crowd of Tesla owners and supporters while formally confirming the company's worst-kept secret: the fact that the Model S sedan's batteries were designed from the beginning to be swapped out. The system Tesla envisioned has plenty of ambitious, techno-wizardry automation, with a focus on as much convenience as possible: The Model S will drive over a pit containing machinery which automatically changes the battery from underneath in approximately 90 seconds -- and the driver doesn't even have to get out of the car.
