The Porsche 997 GT2 is the undoubtedly the king of the 911s, but the crew at SpeedART has decided to add a few more jewels onto the GT2's crown. Beginning with the overly competent twin-turbocharged flat-six, the German tuning haus modified the stock snails, replaced the headers, fitted a new exhaust with freer flowing cats, installed larger intercoolers and tuned it all with a Motronic ECU. Output is now up to 650 hp and 634 lb.-ft. of torque, propelling the BTR-XS 650 to 60 in 3.2 seconds and on to a top speed of 216 mph.

In addition to the extensive work underhood, the modified GT2 gets coilovers fitted at all four corners and custom wheels, while inside, customers willing to plunk down the €27,500 can choose from an endless catalog of interior bits, including sports seats, a new steering wheel and acres of Alcantara.
