Porsche 911 RSR is a hardcore version of Neuelfer intended for racing. The engine has moved midship for better handling and it has been thoroughly reworked to cope with the rigors of endurance training. Now, at the 201

9 Goodwood Festival of Speed, Porsche shows the latest iteration of its bread-and-greased GT racing car.

Porsche on Saturday revealed the 2019 RSR. It will compete in both the FIA ​​World Endurance Championship (in the GTE class) and the IMSA WeatherTech SportsCar Championship series. It replaces the 911 RSR that has already been won 24 hours in Le Mans and eight different IMSA endurance races, including running on Sebring and Road Atlanta.

Based on the 991.2 GT3 RS, the new RSR has a powerful 4.2 liter flat screen six. Depending on the size of the required limiter plate according to the racing rules, the car produces approx. 515 horsepower. In fact, it is the largest boxer engine ever to be mounted in a Porsche 911. The car manufacturer claims that it has better power over a wide band of revolutions than its predecessor.

This power makes its way to the rear wheel through a six-speed sequential racing transmission that has been stiffened to the 2019 model. Instead of equipping the exhaust through the rear bumper, it now leaves the vehicle through a pair of cuts in front of either the rear wheel. This not only saves weight, according to Porsche, it also adds an aerodynamic benefit. Clearing space under the rear bumper enabled Porsche to optimize the rear diffuser for even more downhill than before.

While Porsche has been working on the new RSR since 2017, it really proved worthwhile during March when Porsche drove the car for 30 hours over some 3,700 miles of racing. In what looks like an odds-defying round, the car exhibited no technical issues and it was cleared for racing in early July. After its Goodwood debut, it will turn off the 2019-202 WEC season on Britain's Silverstone track on September 1.

Not only does the exhaust pipes make side-outlet allow Porsche to adjust the diffuser for better aerodynamics, it looks the absolute business, too.
