Porsche's commitment to the KISS philosophy of exterior design won't extend to the engine of the facelifted 911 Turbo, GT2 and GT3 when they're released early next year. All three models will dispatch with the legendary M97 powerplant in favor of the new, direct-injected A91 flat-six that's equipped on the recently updated 911 Carrera.

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.
