Porsche couldn't leave the explosively fast 911 Turbo alone: enter the 911 GT2. The 3.6L flat-6 twin-turbo has been tuned to 456-bhp/457 lb.-ft. A 6-speed manual is standard. The RWD GT2 is 220 lbs. lighter than the 911 Turbo. Top speed is estimated at 195 mph. 0-60 mph (~4 sec.), 0-124 mph (12.9 sec.). 18-inch wheels mount 235/40ZR18 and 315/30ZR18 (F/R) tires. Lighter ceramic disc rotors (PCCB) provide enhanced braking and long service life. A new, driver adjusted 1-piece rear wing distinguishes the GT2 from the 911 Turbo. Other upgrades include a lowered suspension with stiffer springs, transmission oil cooler, and dry sump lubrication
