Video: Michael Mauer on the 991-series Porsche 911

Porsche has released a video featuring its Design Director, Michael Mauer, explaining how he and his team went about redesigning the 911, an ‘automotive, engineering icon' as he describes it. "What we as designers are striving to above all is to optimize the width to height ratio with the result that although the 911's width has not increased, the front axle area has become wider, and we've managed to make the roof a bit lower," Mauer explains via a rather dramatic-sounding voiceover.

Volvo XC60 R-Design revealed

Volvo has released details of an R-Design version of the XC60 Still, more power isn’t everyone’s cup of tea – particularly at the moment – but many buyers like a bit of ‘butchness’ in their cars. And to be completely fair to Volvo, although they haven’t messed with the oily bits for more oomph, they have played with the suspension for more feel. Volvo say the XC60 has improved steering (thanks to ‘Direct Steering Gear’), stiffer damping and a more robust chassis.

Volkswagen hits back, weighs making a bid for Porsche

Volkswagen is considering an audacious reverse-takeover bid for its majority shareholder, Porsche, in a twist in the drawn-out struggle for control between the two German carmakers. The Volkswagen Group's supervisory board is said to be weighing the possibility of purchasing Porsche AG, in a move that would relieve its holding company, Porsche SE, of massive debt that industry analysts suggest the company may not be able to fund should the world's financial crisis drag on well into 2010--a scenario put forward this week by the International Monetary Fund. The secret plan emerged as shareholders were set to convene at Volkswagen's annual meeting on Thursday, and it comes after Porsche revealed that it is carrying some 9 billion euros ($11.73 billion) in debt, most of it owing to interest on loans taken out to purchase its 50.8 percent stake in VW.
