SpeedART Creates the 2010 Porsche 911 Turbo-Based BTR II with 580HP

The new Porsche 911 Turbo is one of the fastest production cars in the market, but that wasn't enough for SpeedART as the German tuner decided to up the ante with the introduction of BTR II 580. Thanks to the reprogrammed ECU and a new sport exhaust system that comes with a sound control switch, SpeedART managed to squeeze another 80 ponies and 120Nm of torque from the 3.8-liter turbocharged flat-six boosting output to 580HP.

That's good enough for a 0-100km/h (62mph) sprint time of 3.2 seconds and a top speed of 325km/h or 202 mph for the PDK double-clutch model. The power kit is priced at €9,890.
