Audi TT Roadster

Following the launch of the new TT earlier this year comes its open sibling, the TT Roadster. Continuing to rebuke the trend for folding hard-tops despite even Mazda providing such an option on the MX-5, the TT Roadster perseveres with a cloth roof instead. Not only saving weight, this also means no visual mass protruding over the belt-line, though like its predecessor the roof adopts a more abrupt profile when raised than the fluidity of the coupe's profile.

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.

Subaru Impreza WRX STI S206: The ultimate Impreza for JDM

Subaru Impreza WRX STI S206 Scooby fans do like a limited edition Impreza, so their collective mouths will be watering at the news that a new Impreza is on the block – the  Impreza WRX STI S206. But before you all get too excited, Subaru has no plans to bring any of the 300 S206s to the UK – they’re all for the JDM and are going straight on sale in Japan, with an S206 taking pride of place on Subaru’s stand at the Tokyo Motor Show next week. Subaru say the S206 is the Crown Jewel of the STI cars, and Subaru have given the S206 a raft of updates over the standard WRX STI.
