Porsche 918 Spyder races toward production

OK, let's put the usual arguments to rest first: The Porsche 918 Spyder is going to be even faster than the Carrera GT in a straight line. That's based on Porsche's own computer simulations in anticipation of the production version of the gasoline-electric-powered 918 Spyder, which is due to roll off a dedicated line within a decommissioned paint shop at Porsche's Zuffenhausen, Germany, headquarters next year. The claimed 0-to-62-mph time is 2.8 seconds; 0-to-124 mph is 8.9 seconds, and top speed should be about 202 mph, thanks in part to series of active aerodynamic functions, including a multistage rear wing.

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.
