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: 345 km/h (214mph).
