Ariel Atom 3.5 (2012) first official pictures

It's difficult for Ariel to come up with a mid-life refresh for its cars - there simply aren't that many bits to fiddle with in the first place.

-- South Korea's automotive legacy may not be as rich as, say, Czechoslovakia's, but don't tell collector Baek Joong-gil that. Not to his face, anyway.

Chevrolet Volt prices announced

GM has revealed that the Volt hybrid could cost $33,500 (£21,000) in the US after government tax credits, making it nearly £2000 cheaper than Nissan’s Leaf electric car. The Volt’s List price is $41,000 (£26,300) but qualifies for a subsidy thanks to its low emissions. A basic Volt comes with Bluetooth and sat-nav but buyers can add leather seats and steering wheel, heated seats, rear camera, polished wheels and park assist.
