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.
