Redesigned Opel Astra revealed ahead of Frankfurt rollout

Opel, General Motors' financially embattled European subsidiary, has ripped the covers from its sixth-generation Astra ahead of the car's planned debut at the Frankfurt motor show in September. The five-door hatchback traditionally is one of Europe's best-selling models and originally was expected to play an important role in the Saturn lineup in the United States. Under GM's pared-down lineup, the Astra's Delta 2 chassis is likely provide the underpinnings for a small Buick, initially in China, and then in the United States, depending on market conditions.

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.
