As expected, Porsche unveiled today at the 2013 Geneva Motor Show the all-new 911 (991) GT3. For those who don’t know, this is the fifth generation of the 911 GT3 and honestly to tell you the numbers are quite impressive. The 991 GT3 is powered by a 3.8-liter boxer engine delivering 475 hp (350 kW) @ 8,250 rpm bolted to a Porsche dual-clutch transmission (PDK) which delivers the power to the rear wheels.
The six-cylinder engine is based on the same engine as the 911 Carrera S, but the two cars share only few common parts. According to the press release, the 991 GT3 features specially developed crankshaft and valve gear, Porsche designed titanium connecting rods and forged pistons.
The Porsche dual-clutch transmission was also specially developed. With a power to weight ratio of 3.0 kg/hp, the 991 GT3 is able to hit 100 km/h (62 mph) in just 3.5 seconds and has a top speed of 315 km/h or almost 196 mph. Moreover, the Porsche 991 GT3 is able to hit 200 km/h (124 mph) from a standstill in just 12 seconds.
The lap time on the Nürburgring Nordschleife, which the new 911 GT3 manages in under 7:30 minutes, is even more impressive. Comparing it with the Porsche 991 Carrera S, the new GT3 is 44 millimeters wider in the area of the rear axle and features a fixed rear wing.
This makes a decisive contribution to the exemplary aerodynamics of the new 911 GT3, which combines low air resistance with even more power. For those who want a 991 GT3, this vehicle will be launched on the market from August 2013 and will cost in Germany 137,303 Euro including VAT and national specifications.
