The Porsche 911 RSR-19 is a racing car developed by Porsche to compete in the LM GTE category of the FIA World Endurance Championship and European Le Mans Series, and the GTLM category of the IMSA SportsCar Championship.

[2][3] The car was unveiled at the 2019 Goodwood Festival of Speed, at the timing gantry of the Hillclimb circuit, just moments before its first public run, with Gianmaria Bruni at the wheel.

[8] In May 2019, ahead of the 2019 24 Hours of Le Mans, one of the prototypes was spotted at the Autodromo Nazionale Monza, being pitted against its predecessor.

[5] Power comes from an upsized, rear-mid mounted six-cylinder naturally-aspirated 4.2 litre (4.194 litre) engine, the largest ever boxer configured engine in a works 911 racing model, paired with a faster sequential six-speed constant-mesh gearbox.

The exhaust has also been relocated to the side, allowing for a larger diffuser to be installed, increasing the base downforce of the car.
