Rolls Royce Wraith Drophead Coupe confirmed for production.

The Rolls Royce Wraith (pictured) will get a Drophead sibling in 2016 It was always likely that Rolls Royce would take their ‘affordable’ model – the RR Ghost – and make a coupe version. What wasn’t really on the cards is that they would give it a more dramatic style – and a more driver-focused experience – and tag a name from the past on it to create a new Rolls Royce Wraith for the 21st century. But that’s exactly what they’ve done, and the Wraith does seem to be an effective tool for Rolls Royce to extend the appeal of their cars to a new, perhaps younger, demographic.

Mercedes GLA 45 AMG: OFFICIAL

Mercedes GLA 45 AMG: OFFICIAL After the arrival of the Mercedes A 45 AMG – and its swoopy coupe sibling CLA 45 AMG – it was always more than likely that Mercedes would launch a GLA 45 AMG, and we saw the first evidence of that with the debut of the Mercedes GLA 45 AMG Concept at the Los Angeles Auto Show in November. But now, Mercedes has the production version of the GLA 45 AMG ready to go and we get the first photos and details ahead of its debut at the Detroit Auto Show next month. Powered by the same 355bhp 2.0 litre turbo as the A 45 AMG and CLA 45 AMG, the GLA 45 AMG manages to get to 62mph in 4.8 seconds (0.2 slower than the A 45 and CLA 45) and manages official economy fo 37.6mpg and 175g/km (but not in the real world).

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.
