2012 Tesla Model S moves toward production

WITH VIDEO -- We have new video of Tesla’s Model S sedan, which is supposed to arrive on the market next year. We’ve seen pictures of this car but now it’s actually moving. There are clear views of the sleek, almost Aston-like appearance of this car, and it’s pretty handsome.

Mazda's rotary engine stalled, not forgotten

Development of the next-generation rotary engine from Mazda Motor Corp., first unveiled three years ago, is making slow progress despite missing emissions targets. A top Mazda powertrain executive said today that the 1.6-liter rotary engine, called the 16X, is about 30 percent more fuel-efficient than the current rotary engine used in the RX-8 sporty car. In fact, the 16X so far performs slightly better than Mazda's standard two-liter gasoline engine, said Mitsuo Hitomi, general manager of the Japanese carmaker's powertrain division.

Aston Martin DB9 4WD Plug-in Hybrid revealed by Bosch (video)

Bosch has built a plug-in hybrid Aston Martin DB9 We’ve always believed one of the best uses for hybrid powertrains is to provide extra performance on high-end cars, something Bosh has demonstrated by fitting the Aston Martin DB9 with a hybrid setup. The hybrid DB9 hasn’t been built to preview a production hybrid DB9 (although it probably should) but to demonstrate what Bosch can do with an existing car. Aston Martin donated the DB9 to Bosch for the hybrid project, and Bosh has fitted the DB9 with three electric motors – one at each front wheel and one next to the Aston’s V12 – which gives the DB9 something in the region of an extra 250bhp to play with.
