TechArt Automobile Design of Germany has unveiled its latest, the GTstreet R, a highly tuned version of the Porsche 911 Turbo.

TechArt continues its re-inventions of Porsche supercars. Just last spring TechArt presented the GTstreet RS, its specialised version of the Porsche 911 GT2. Now, its latest creation is based on the 911 Turbo which TechArt, located in the same region of Germany as Porsche, has turned into one impressive performer. As if the 911 Turbo wasn't one already.

The GTstreet R comes fitted with TechArt's performance kit TA097/T3, which sounds like something out of a science-fiction movie. What all those letter and numbers mean is 660 hp and a maximum torque of 860 Nm at 4,600 rpm for this re-imagined 911 Turbo. Coupled with Porsche's Tiptronic S transmission, it takes the GTstreet R a mere 3.4 seconds to reach 100km/h.

TechArt  takes the 911 Turbo's standard 3.6 liter turbocharged engine and boosts its performance with new turbochargers, special intercoolers and a host of other technological tidbits that make this horse run a lot faster.

Top speed? How about an insane 345 km/h (214mph). Does that suit you?
