Porsche still celebrating 911 50th birthday (video)

All 7 generations of the Porsche 911 (pictured) ‘sing’ Happy Birthday Car makers do like to make the most of any anniversary they can hang a bit of PR on, and Porsche are no different. 2013 is the 50th anniversary of the, now iconic, Porsche 911 and Porsche has been making PR hay all year with everything from a 50th anniversary 911 to a huge gathering of Porsche 911s at the Silverstone Classic. But now, with just a few months of the 911′s anniversary left to milk the PR, Porsche has put together a video featuring all seven generations of the 911, happily wishing themselves a ‘Happy Birthday’.

This is the new Audi S1

Audi has turned its limited-production Audi A1 Quattro into a full series-production model with the three-door S1 and five-door S1 Sportback. Designed to take on the likes of the new Mini Cooper S, the new entry-level Audi S models make their world debut at the Geneva show early next month. Audi says the S1 and S1 Sportback won't be sold in the U.S.

Chrysler 300

The Detroit Motor Show will see Chrysler unveil its 2011 300. Whilst benefiting from an extensive exterior refresh, the platform on which it is based remains unchanged, meaning that this 2011 model is little more than a face-lifted variant of the car that joined us in 2004. The exterior of the 300 loses some of its forbearer's sinister styling; its imposing face has been substituted in favor of a softer, more rounded style, intersected only by the muscular wheel arches.
