TechArt Porsche GTstreet

GENEVA — German tuner TechArt continues to evolve its variations on the classic Porsche 911 Turbo. Its latest endeavor, called GTstreet, will make its debut at the Geneva auto show.

TechArt conjured up a GTstreet edition of the previous-generation 911 Turbo in 2001. The most recent iteration, based on the 997 body, takes Porsche's legendary twin-turbo 3.6-liter flat-6 engine and squeezes out 630 horsepower (up from 480 hp) and 605 pound-feet of torque (up from 457 lb-ft).

The boost in output results in breathtaking performance figures: 0-60-mph acceleration in less than 3.2 seconds and a top speed of 214 mph.

TechArt also provides a full aero body kit for the GTstreet, and the usual interior modifications.
