Audi TT RS (2009) teaser pictures and audio

By Alex Michealides First Official Pictures 20 February 2009 16:30 These are Audi's first (teaser) pictures of its new TT RS. It'll be Ingolstadt's hottest ever TT, with over 300bhp from its 2.5-litre turbocharged engine. To whet your appetite a little further Audi has also released an audio clip of the TT RS in action, which you can listen to here. We'll see the car in full at the Geneva motor show in less than two weeks time.

Peugeot Onyx concept [w/Gallery]

Peugeot has previewed its Onyx concept, set to debut at this month's Paris motor show, just days after the first teaser images were released. Very much a supercar in terms of its proportions and form, the Onyx is not the first time Peugeot's previewed super and super-sports cars in concept form, but the Onyx looks a lot more promising than previous efforts, from these photos at least. Conforming to the modern, eco-conscious supercar norm, the Onyx features a hybrid drivetrain - following in the footsteps of the BMW i8, Honda NSX and Jaguar CX-75.  Peugeot's stated aim is to push itself upmarket and become a more premium brand, so the Onyx could be read as a sign that the company feels it needs more of a 'halo' car in order to achieve that aim.
