Audi TT GT4 concept

Audi is tossing out a line in the shape of a new concept car to see whether or not its customers will bite. This new concept is called the GT4 and is based on the TT sports model. Production for the GT4 concept is planned for the 2012 model year with sales starting at 120,000 Euro on both European and Asian markets.

The TT GT4 features a motorsport body with a roll-over cage and a safety-optimized fuel tank box, as well as other modifications appropriate for an affordable motorsport vehicle. The exterior sees the front apron, rear apron, and the rear wing borrowed from the Audi TT RS. The new hood, doors, and trunk lid are all made of CFRP while the windows are made of plastic.

Audi has equipped the GT4 with a TFSI engine producing about 340hp. This is handled by an S-tronic transmission with a differential lock and a modified production suspension with adjustable dampers. The vehicle is finished off with 9.5 x 18 inch light alloy wheels.

Audi RS7 Sportback

The Audi A7 is a car with a very short history in the automotive industry. Previewed by the Sportback Concept at the 2009 Detroit Auto Show, the production version of the A7 Sportback is already on sale, albeit not on all markets. This vehicle may be great in its own right, but it will be mediocre in comparison to the RS7 version undoubtedly in the works.

Audi hasn’t exactly offered any details on this future model, but following the tradition of every other model in the line-up, we know for a fact that we will see an RS7. And while the Audi A7 targeted models like the Mercedes CLS and the BMW Gran Coupe, the RS7 will focus on models like the Aston Martin Rapide while serving as a much cheaper alternative.

The Audi RS7 is expected to be revealed sometime in 2011, with sales to begin in early 2012.

Mercedes-Benz SLK Final Performance RS by Piecha

While everyone is waiting for the new R171 generation Mercedes SLK, tuners are still preparing some cool packages for the recently discontinued model. One of those tuners is Piecha Design who have prepared the “Final Performance RS EDITION,” in order to say good bye to a pretty cool car.

The send-off package includes a distinctive front-spoiler bumper with integrated LED daytime running lights, wedge-shaped side skirts with air intakes, a rear bumper with a wide grid core and diffuser vane, and a rear spoiler lip. The vehicle also carries Piecha dp2 Phantom rims in a 19 inch (front) & 20 inch (rear) size with the use of 225/35 front tires and 265/25 rear tires.

The package also includes lowering springs from H&R, a new set of dp2 Phantom rims, black anodized aluminum aero wings, and special wind deflector with the signed “Final Performance RS Edition” logo. These additions are pretty cool, but the highlight of the vehicle is the legendary PIECHA power converter. This converter allows the vehicle to take in all of the power of the engine without even thinking twice about it. We’d love to tell you the amount of power this converter is facilitating, but Piecha have yet to announce these numbers.

Audi RB-1200 S Performance Bike Concept

If BMW does it, why wouldn’t Audi? We are talking about the production of sport bikes, and this new design from the mind of Gavin Harvey combines different sports car elements to create a pretty ingenious piece of work. It’s called the Audi RB-1200 S and it definitely gets our seal of approval.

The Audi RB-1200 S has R8 lights and new front brakes colored in the now famous Audi red. Splashed across the front is Audi’s well-known four circles engraved into the metal. The bike’s seat will be made from leather and will also have carbon fiber detail. Right under the seat, along with the rear lights, is where the designer envisioned the location of a twin exhaust.

Harvey’s design may be a work of art, but we’ve seen renderings of Audi bikes before and nothing much has come of them. Maybe we’ll get lucky with the Audi RB 1200 S. So, what do you think? Should Audi start developing sports bikes?
