IMSA: New 911 RSR tackles another reliability test

With the six-hour race at Watkins Glen on 2 July the IMSA SportsCar Championship picks up pace again after taking a break for the 24 Hours of Le Mans. The Porsche GT Team sends two new 911 RSR to contest the event in the US state of New York.

The racer, designed from scratch by Porsche Motorsport in Weissach based on the seventh generation of the iconic 911 sports car, tackles the strongly represented GTLM class. In the GTD category, customer teams campaign the Porsche 911 GT3 R. The Porsche squad travels to Watkins Glen as the leader (driver and team) of the North American Endurance Cup. The other three events that make up this prestigious long-distance reliability competition are Daytona, Sebring, and Petit Le Mans.

As a completely new development, the 911 RSR celebrated its race debut in January 2017 at the Daytona 24-hour race. It 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 new 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 368+kW (500 hp) customer sport racer celebrated its first 2017 victory at Daytona.
