Though based largely on the 911 GT3, the GT3 RS makes use of an uprated 4.0-litre straight six engine that develops 500PS of power and 460Nm of torque - 25PS and 20Nm more than the 3.8-litre unit powering the GT3. From standstill, 100kmph comes up in 3.3 seconds and 200kmph, in 10.9s. The GT3 RS' engine is the largest and most powerful engine on any production Porsche currently.
Though Porsche hasn't given out an exact figure, the company claims that the 911 GT3 RS has lapped Nrburgring's Nordschleife in under seven minutes and twenty seconds, which is at least five seconds quicker than the GT3 (7:25.0) and significantly quicker than the Carrera GT (7:28.0) and the 911 GT2 (7:32.0).
