First Sight: Mercedes-AMG GT

“If I was to buy any sports car that wasn't a Mercedes, it'd be a Porsche 911,” says Mercedes' head of design, Gorden Wagener. “But when you see the two cars together, we think ours has the edge.” He's talking about the new Mercedes-AMG GT, a front-mid engined, two-seater sports car that's unashamedly aimed at higher-end 911s, and we've come to see it at Mercedes' Sindelfingen studio.  The GT replaces the larger SLS, and is seen by Wagener as the best example yet of his 'sensual purity' design philosophy: “The SLS is very much [he gestures] line, line with a surface in between.

2013 Aston Martin Vanquish: New photos and new video

The new Aston Martin Vanquish is heading for Paris 2012 and Aston Martin has released new photos and video of their range-topper. The 2013 Vanquish gets extra power – it now delivers 565bhp and 456lb/ft of torque – which propels it to 62mph in 4.1 seconds and on to 183mph, sharper new looks with hints of the One-77 and lots of carbon fibre, and a new list price that is still the right side of £200k – £189,995. And perhaps delivering new photos and video of the 2013 Vanquish is Aston Martin’s way of making sure the Vanquish has its moment in the sun ahead of the reveal of the new DB9.
