The GT3 RS is a high performance version of the GT3 with a higher engine power output, lower weight and shorter transmission ratios, as well as having upgraded body and suspension components, designed for homologating the race version of the 911 GT3.
The engine was rated at 450 PS (331 kW; 444 bhp) at 7,900 rpm and 430 N⋅m (317 lb⋅ft) at 6,750 rpm with a maximum engine speed of 8,500 rpm.
The "RS" stands for "rennsport", the German word for "racing" (literally, "race sport").

The transmission has shorter ratios than found in the 911 GT3 for improved acceleration.
Dynamic engine mounts are standard and serve to improve the car's handling to an even higher level.
Other features include PASM suspension, titanium connecting rods, a wider front and rear track, a large fixed rear wing made from carbon fibre, a standard roll cage, and corresponding decals.

Optional equipment included a lithium-ion battery, which is 10 kg (22 lb) lighter than the stock lead-acid battery.
The vehicle was unveiled at the 2009 Frankfurt Motor Show.
The US model was set to go on sale in early spring of 2010 with an MSRP of US$132,800.
