The reference ''RS'' will quicken the pulse of Porsche connoisseurs. Models such as the legendary Carrera RS 2.7 of 1972 and the 1991 Type 964 911 RS were also sports cars that stood out on account of their extreme degree of maneuverability and handling. That tradition is continued with the new 911 GT3 RS. In common with its predecessors, it provides an homologation model for use in a range of racing series.

The exceptionally powerful, normally aspirated engine boasts a displacement of 3.6-litres to generate 415 bhp at 7,600rpm. Maximum revs are reached at 8,400rpm. The power output per litre of engine capacity is 115.3 bhp. These figures are shared with the recently-announced 911 GT3, but bespoke drivetrain components in the RS ensures it puts in an even better performance. Thanks to a close-ratio six-speed transmission with a single-mass flywheel and 20kg lower vehicle weight, the engine revs up even more freely.

One characteristic of the RS is the body, which is 44mm wider at the rear (a legacy from the Carrera 4 models with which it shares its shell) by comparison with the 911 GT3. The muscular-looking rear end conceals a wider track that not only improves directional stability but also increases the potential cornering grip of the two-seater coupe.

Despite its specialised body, the RS is 20kg lighter than the GT3, weighing in at just 1375kg. This weight-saving was achieved by the use, amongst other solutions, of an adjustable carbon fibre wing, the use of a plastic engine cover and a lightweight plastic rear window. As a consequence, the corresponding engine power to weight ratio is over 300bhp per tonne.

The example on offer here is a January 2007 model presented in black with orange mirrors, wheels, cage, script and wing endplates. The vehicle has covered 12000 miles and was fully serviced by a main dealer in January at which point a 111 point Porsche check was completed and the warranty was also extended.Extras on this model include; Factory Sat Nav, Red Belts and callipers, Carbon interior, leather steering wheel, removable race harnesses, top tinted windscreen and separate extinguisher.
