Porsche has unveiled the new and improved 911 RSR at Goodwood Festival of Speed, which it plans to use in the FIA World Endurance Championship, starting with the 2019/20 season.
This new version of the RSR is powered by a new naturally aspirated six-cilinder boxer engine, which is the biggest engine ever to be used in a 911 at 4.194cc. Depending on the size of the restrictor, the new engine will produce around 515 bhp.
“Since 2017 the 911 RSR has yielded us more than 20 class wins in the world championship as well as at long-distance series in North America and Europe. Our job in the development was to make a very good car even better. The engineers at Weissach have perfectly implemented this in every aspect,” says Fritz Enzinger, Vice President of Porsche Motorsport.
“We never rest on our laurels,” explains Pascal Zurlinden, Director of GT Factory Motorsport. “We’ve extensively analysed all factory and customer campaigns with the Porsche 911 RSR. Our engineers noticed room for improvement in a number of areas. We have made significant progress in the development of our car for the next three-year homologation period, especially in the complex areas of driveability, efficiency, durability and serviceability.”
Zurlinden goes on to explain how rigorous Porsche has been in the development of the new car: “Ninety-five percent of the car is new. The only components that we’ve kept unchanged from the predecessor are the headlights, brake system, clutch, driver’s seat and parts of the suspension. Tests so far have run excellently. We’re already looking forward to the first races of the 2019/2020 FIA WEC season.”
The new car will make its competitive debut in the 2019/20 FIA World Endurance Championship. Porsche’s driver line-up remains unchanged. The #91 is set to be driven Richard Lietz and Gianmaria Bruni, while champions Kevin Estre and Michael Christensen return to the #92 car. The car will make its debut in American competition in 2020 when the new IMSA Weathertech Sportscar Championship season kicks off. Customer teams will be eligible to use the new car from the 2020/21 season.
