Based on the road-going 996 911 GT3 RS, the GT3 RSR features improvements to its predecessor in all key areas. The vehicle is available in an ACO (Automobile Club de l’Ouest) version for competing in Le Mans and in the American Le Mans Series as well as in a FIA specification. The 911 GT3 RSR features a modified front which improves downforce at the front axle.
The 3.6-litre, six-cylinder boxer engine delivers 445 hp at 8,250 revs. Maximum torque is now 405 Nm at 7,200 rpm, with top revs reached at 8,500. New pistons and rods as well as a new valve gear result in a moderate power increase with the focus on further-improved driveability and durability. A characteristic feature of the 996 RSR is its air-inlet which generates ram pressure.
For the 2004 and 2005 racing season, Porsche Motorsport used the 911 GT3 RSR. This near-standard racing sportscar aimed to keep private customer teams competitive in international Gran Turismo sport and to continue the success of the predecessor model which won its class at the Le Mans 24 Hours five times in succession, became a record and title winner in the American Le Mans Series as well as the FIA GT Championship, and secured the overall win at this year’s Daytona 24 Hour race.
