Facts and figures for the 911 RSR

The Porsche 911 RSR is a complete new development. The most important innovation is the engine installed in front of the rear axle. Through this de facto mid-engine design, the crew of Porsche achieved a better weight distribution and managed at the same time space in the rear for a larger diffuser, which generates significantly more downforce. The development of the new 911 RSR began at the beginning of 2015. Experience with the predecessor model and current requirements of the regulations led to the conception of the new athlete. As early as ever, drivers have been involved in the development, according to Porsche to Modellauto News: "Only then, at the end of a busy stint, will they be able to deliver the top performance needed to succeed in the challenging competitive environment to be."

A total of seven 911 RSRs were built at Porsche Motorsport in Weissach for the 2017 season: two each for use in the WEC and the IMSA SportsCar Championship as well as three test cars. With the construction of a 911 RSR, four employees work ten working days. The first car drove the new car in March 2016 on the Porsche test track in Weissach. The highlight of the test phase was a 50-hour endurance race in Sebring. "As far as I know, no other manufacturer has dared to do that," said Marco Ujhasi from Porsche.

The displacement is 4,000 cubic centimeters, the power depending on the restrictor about 375 kW / 510 hp. Compared to a turbo 40 kilos lighter and according to Porsche highly efficient unit has a direct injection gasoline and a rigid valve train. The engine was put to the test for the first time in about seven months. The testing program started after almost a year. It contained two 70-hour endurance runs in different weather conditions.
