2010 Geneva Motor Show: 2010 Techart GTStreet R

The 2010 Geneva Motor Show is just days away, and the list of vehicle debuts is seemingly never ending. Last week Techart announced that they would be bringing their modified 2010 Porsche 911 Turbo, and today the German tuner previewed two more new cars that will debut at the show.

The first is an all-new version of the GTStreet R model. Based on the 2010 911 Turbo, the GTStreet R is about serious performance. The 3.8-liter twin-turbo flat-six produces 660 horsepower and 635 pound-feet of torque, and Techart claims a 0-100 km/h time of 3.5 seconds as well as a top speed of 214 mph. Providing the looks to go with the power is an aggressive aerodynamic kit that includes an adjustable rear spoiler and carbon fiber rear diffuser and front splitter.

The second vehicle is the Concept One, a design study based around the Porsche Panamera. Unlike the GTStreet R, the Concept One is less about go (although it does have a 550 horsepower twin-turbo V8) and more about go. The exterior features a full body kit as well as 22-inch forged wheels. The inside is upholstered in a striking white and cocoa leather complimented by phosphor green stitching. Even Techart calls it "unusual personalization." You can check out both cars in the high-res galleries below and get more info after the jump.
