The 345 km/h Porsche 911 Turbo TechArt GTstreet

German company TechArt Automobildesign has created one of the fastest and most powerful street-legal sports cars available which will see its world debut at the Geneva Motor Show 2007. The new TechArt Gtstreet is based on the 997 series Porsche 911 Turbo and has an extraordinarily powerful engine, having tweaked the 3.6-liter twin-turbo boxer engine to develop 630 hp / 463 kW at 6,800 rpm, up from standard 480 hp / 353 kW. Peak torque has been increased from 620 Nm to 820 Nm at 4,500 rpm, giving it a 0–100 km/h time of 3.2 seconds, 0–200 km/h of 10.9 seconds and a top speed of 345 km/h. The body kit for the TechArt GTstreet was created in the wind tunnel, and offers an optimal symbiosis of aerodynamic downforce, minimized drag and striking design.
