The brutal GT2 RS is the chainsaw of the 911 lineup compared with the scalpel-like GT3. Its 700-hp twin-turbo flat-six drives the rear wheels through a seven-speed dual-clutch automatic for a claimed 2.7-second zero-to-60-mph time—conservative, we think—and powered this fastest-ever 911 to a record lap at the Nurburgring Nordschleife. Steering is laser direct, and the rear slides—controllably—if directed; the brakes are amazing, with no fade present during repeated high-speed stops on track. The name isn't hard to decode, and we understand if your first instinct is to feel that this will be a familiar story. While GT3 versions of the 911 use high-revving naturally aspirated engines to give what is almost a perfect balance between performance and grip, GT2s use turbocharged engines to deliver a more brutish appeal and a generous excess of power. The RS addendum stands for Renn Sport and indicates this car's track-centric mission. Whereas the previous-generation GT2 had an already gratuitous 620 horsepower, this new 991 edition moves that number up to a credibility stretching 700 horses, courtesy of a twin-turbocharged 3.8-liter flat-six with a water-spraying system to cool its intake charge. Peak torque, a modest 553 lb-ft, is delivered to the rear wheels through a seven-speed dual-clutch automatic transaxle (PDK); unlike the GT3, there is no manual option. hat's because the GT2 RS is built for speed, both in a straight line and around road-racing circuits. Its statistics are as eye popping as you would expect for the fastest ever factory-built 911. Some obsessive trimming of mass extends so far as to include both lightweight carpets and extra-thin glass closely related to that used in cellphone screens. The optional weight-trimming Weissach package shaves 40 pounds at the cost of an extra $31,000, with Porsche claiming a curb weight of just 3241 pounds, although that means forgoing both the infotainment system and air conditioning. Small wonder that Porsche claims a 2.7-second zero-to-60-mph time and that we estimate the car can burn a quarter-mile in 10.3 seconds. The top speed is—get this—limited to 211 mph, in the interest of keeping the track-biased tires in one piece.
