The race car, which faces strong competition in the fiercely contested GTLM class, was completely redesigned by Porsche Motorsport in Weissach based on the high-performance 911 GT3 RS sports car. On 22 July at Lime Rock, the racer scored its maiden victory. Porsche’s customer teams are also strongly represented on the tradition-steeped 5.263-kilometre racetrack close to Danville in the US state of Virginia, campaigning four 911 GT3 R in the GTD class. Like at Lime Rock, the prototypes will not contest the third to last race of the season, which means that overall victory will definitely go to a GT vehicle.

The new 911 RSR

The 911 RSR is a completely new development and is campaigned by the Porsche GT Team in both the IMSA SportsCar Championship and the Sports Car World Endurance Championship WEC. Depending on the size of the restrictor, the motor, which is now positioned in front of the rear axle, puts out around 375 kW (510 hp). The level of downforce and the aerodynamic efficiency were significantly improved. The 911 GT3 R, mounted with the ultra-modern four-litre, flat-six engine with direct fuel injection, was designed by Porsche for worldwide GT3 series on the basis of the 911 GT3 RS production sports car. The more than 368 kW (500 hp) customer sports racer kicked off the 2017 season with a class victory at the 24 Hours of Daytona.
