Infiniti FX designed by Sebastian Vettel (2011)

This bespoke one-off Infiniti FX has been designed by reigning F1 champion Sebastian Vettel - and it'll be at the 2011 Frankfurt motor show. Vettel, who drives for Red Bull Racing, is also an ambassador for Nissan's upmarket car division. Infiniti is a sponsor of RBR, and so Vettel is often seen at Infiniti events.

Volvo S60 Polestar goes in to production

It sounded like a plan to put it in to production – even if it would probably need twin turbos to make it nicely wieldy on the road – and that’s exactly what Volvo and Polestar have done. The Volvo S60 Polestar has gone in to limited production, initially for the Australian market, but instead of the mighty 508bhp of the concept it has to make do with a more pedestrian 350bhp, little more than the V60 we reviewed last year with the Polestar upgrade. But the extra power is enough to get the production S60 Polestar to 62mph in 4.9 seconds and, thanks to tweaks to the suspension, brakes and aerodynamics, the S60 Polestar looks like it will be able to handle the power quite well.

Audi TT Offroad shows off at Beijing auto show

Audi introduced the TT Offroad concept at the Beijing motor show last week. The company says it comes with a plug-in hybrid drive system delivering 408 hp total, while getting 123.8 miles per gallon -- impressive, but we're guessing not exactly real world. To get that power, the TT Offroad concept uses the company's 2.0-liter turbocharged four-cylinder, making 292 hp and 280 lb-ft of torque.
