Video: GM's Clay Dean on the future of urban mobility

Clay Dean is the star of a new Faces of GM video, Anticipating the Driving Experience of the Future. The global design director for GM's Advanced Design Group, whose job also entails exploring future transportation design solutions, talks about the need to avoid short-term thinking on urban mobility, as by 2030 60 percent of the world's population will live in cities. As new challenges start to emerge, such as increasing congestion, Dean believes it is time to start thinking about transportation in a completely different way.

Tiff Needell compares the 911 and F-Type

It was a mere matter of time before somebody pitted the new Jaguar F-Type against a flat-six-powered automobile from Stuttgart. And while our natural inclination would've been to choose the mid-engined, two-seat Boxster S to mash heads with the 380-horse V6 S model, the lads at Evo had Tiff Needell compare the new Jag to a 911 Carrera Cabriolet. The heavier Neunelfer is a closer power/weight match to the F-Type.

2014 Mercedes S Class: First interior photos

We have the first interior photos of the 2014 Mercedes S Class ahead of its debut in May 2013, showing a much more modern interior. But now, with a reveal of the new S Class just a couple of months off, we have the first photos of the interior of the new S Class showing a  car that keeps much of the layout of the current S Class but adds in more curves, more technology, a more modern look and a more upmarket feel than ever before. The cabin flows from the screen in to the doors in the same sort of seamless way it does an the Jaguar XJ – where it makes the cabin feel more spacious – the instrument panel is a huge digital display, the seats are differently contoured and trimmed, there seems to be more room, better lighting and an altogether more upmarket feel for Mercedes range topper.
