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.

Nissan Extrem concept

Nissan has unveiled its Extrem concept at the Sao Paolo motor show, a two-door 2+2 crossover that previews future Nissan design cues. The Extrem concept was designed at Nissan Design Center (NDA) in San Diego, California, in collaboration with Brazilian designers but much of the creative time was spent in Sao Paolo. "We call it Baby Beast," said Robert Bauer, Senior Design Manager for the project at NDA.

Buy a brand new car on Amazon

Online retail giant Amazon is now promoting vehicle sales on its website, advertising the new Nissan Versa Note supermini for $13,990 (around £8,630) on the US arm of its Internet-based department store. However, the firm isn’t directly selling the cars – it is instead ‘promoting’ the vehicles. The Nissans do get a full listing, though, as opposed to the simple hosted advert often seen elsewhere online.
