The Manthey-Porsche of Uwe Alzen, Patrick Huisman and Luca Riccitelli won the class ahead of the Champion-Porsche of Dirk Müller, Bob Wollek and Bernd Mayländer.

In the 2000 FIA GT Championship, the 996 GT3 R was the dominant vehicle in the new N-GT class and won every run.

Jörg Bergmeister and Timo Bernhard prevailed against the much more powerful prototypes in the 2003 24-hour race in Daytona.

In 2003, Stéphane Ortelli, Marc Lieb and Romain Dumas won the Spa-Francorchamps 24-hour race for the first time in the history of the FIA GT Championship in an NGT vehicle.

The engine output fell to 331 kW (450 PS) due to the air flow limiter stipulated by the regulations.

In the race, the Porsche works drivers Jörg Bergmeister, Patrick Long and Marc Lieb narrowly missed the podium in the GT2 class after two collisions.

Lieb and Lietz achieved their first class win at the 1000 km race in Barcelona in the Le Mans Series.

The 991 RSR debuted in 2013 and for the first time was not based on the GT3 model of the 911, but on the Carrera 4S, as the street version of the GT3 was introduced too late for homologation.

[6] At the time, the GTE regulations allowed special technical permits (waivers) to be requested in order to compensate for objective concept disadvantages, such as those of the rear engine.

It was known that waivers were approved for the side air intakes, the vehicle width, the height of the underbody, the double wishbones at the front and the engine.

For the 2016 season, new GTE regulations came into force, which were intended to improve driver safety and increase the performance of the vehicles.

The performance of the GTE vehicles was achieved through an engine output that was around 20 hp higher and at the same time 15 kg less weight.

[8] However, this vehicle was unable to fully exploit the freedom of the new regulations, which is why it was inferior to the Ford GT and Ferrari 488 in the 2016 season.

The chassis, body structure, aerodynamic concept, engine and transmission were completely redesigned.

[10] This enabled two decisive advantages to be gained: firstly, the weight distribution was improved, which benefits tire use, and secondly, there was space for the larger rear diffuser permitted in the new GTE regulations.

[14] The Manthey Racing team achieved a double victory in the GTE Pro class at the 2018 24 Hours of Le Mans.

Only components such as headlights, brakes, clutch, driver's seat and parts of the chassis were taken over from the predecessor unchanged.

[16] In addition, the exhaust system has been changed to two tailpipes that end at the side in front of the rear wheels.

The new exhaust gas routing has advantages in terms of weight, aerodynamics and vehicle contact on the racetrack.

In addition, the naturally aspirated six-cylinder boxer engine was enlarged to 4.2 l displacement with almost the same output in order to improve torque development.
