This is the new Porsche 911 RSR GTE race car

Fresh from wrapping up the GTE class Driver’s and Manufacturers’ titles in the FIA World Endurance Championship, Porsche unveiled it’s brand-new race machine at the Goodwood Festival of Speed – the Porsche 911 RSR GTE.

It’s based on the old 991.2-generation race car – rather than the recently-launched 992-gen road car – but 95% of it is brand new. According to Porsche, only the headlights, brakes, clutch, bits of the suspension and the driver’s seat have been carried over.

Power comes from a new 4.2-litre, flat-six engine – up from 4.0-litres, making it the biggest engine ever put in a factory 911 racer. Power output will ultimately be determined the GTE class’s Balance of Performance system, but will likely be somewhere between 550hp and 600hp.

Porsche moved the engine ahead of the rear axle for the previous 991.2 car, allowing a much more effective rear diffuser to be used. The new car maintains the mid-engined layout and gains a new exhaust system that exits ahead of the rear wheels, freeing up even more space for that diffuser.

The bodywork is made from lightweight carbonfibre-reinforced plastic, clothing an aluminium and steel bodyshell. All-up weight is just 1,245kg.

The Porsche factory team will start racing the new 911 RSR when the 2019-20 FIA World Endurance Championship season starts at Silverstone on 1 September. The Porsche North America squad will run it from the start of the 2020 IMSA SportsCar Championship.

Customer GTE Am teams will be able to buy one for the 2020-21 FIA season. Until then they’ll have to make do with the old car. Still, gives them time to save up the million dollars or so the new car will cost.
