VW Design Vision GTI gets 500bhp: Worthersee

The Design Vision GTI is built to show what a Golf built for racing would look like – and perhaps point to future evolutions of VW’s most successful car – and is built on the same MQB platform as the regular GTI. It’s a bit shorter (15mm) than a regular Golf, a chunk wider (71mm) and a lot lower (57mm) which conspires to make the Design Vision GTI much more aggressive looking than its mainstream sibling. Power comes from a 3.0 litre V6 with two turbos – good for 500bhp and 413lb/ft of torque – which is driven to all four wheels through a DSG ‘box and can scoot to 62mph in a supercar-like 3.9 seconds on its way to 186mph.

Smart For-Us concept unveiled at 2012 Detroit show

Smart made a splash with its world debut at the 2012 Detroit auto show: its For-Us concept car provides a vision of the Smart as an American icon, a pick-up. The diminutive truck - just 3547mm long - is longer than a Fortwo, and is supposed to be based on the running gear of the next-gen Smart Forfour, aka the new Renault Twingo. So if the For-Us doesn't look so much like a Smart any more, from the front at least, that's why.
