Porsche Endurance Trophy Nürburgring

In 2016 the "Cayman GT4 Trophy by Manthey Racing" was introduced in the Nürburgring Langstrecken-Serie (NLS) as a racing series for the Cayman GT4 Clubsport (981). In Cup 3 class up to 21 cars were racing against each other forming a substantial part in endurance racing on the Nordschleife. In 2022 whith the addition of the Cup 2 class for the 911 GT3 Cup, the Porsche Endurance Trophy Nürburgring was founded as an official Porsche one-make series.

With the Talent Pool, the PETN is taking an important step towards developing young talent on the Nordschleife. The aim of this programme is to specifically promote young talent and support them on their way in motorsports. It includes an extensive workshop programme and driver training, including a visit to the simulator at Manthey in Meuspath. At the end of the season, the ‘PETN Junior’ will be selected by a committee based on criteria for driving development and soft skills, and will receive funding for the following season in the PETN through additional incentives for the team. The requirements for participation are a maximum age of 24, experience in motorsport and an annual registration in the PETN.

In the PETN two cars are eligible to race. The Porsche 718 Cayman GT4 CS (982) is competing in Cup 3 class and the Porsche 911 GT3 Cup (992.1) is racing in Cup 2 class. Both cars have a special PETN specification to optimise them for the unique demands of the Nordschleife. This specification includes ABS and TC for the 911 GT3 Cup, as well as tank systems that allow the cars to be refuelled through the front bonnet.

Due to the multi-class racing on the Nordschleife and the unique characteristics of the track, drivers require extra awareness for the speed difference of the different cars. This is ensured by a special licence for the Nordschleife, the DMSB Permit Nordschleife (DPN) Grade A. In the Cup 3 class of the PETN, the Porsche 718 Cayman GT4 CS (982) can be entered in a performance-reducted specification (Permit B) that allows drivers to obtain this license. Max Verstappen, for example, took this route and obtained his Nordschleife license in Cup 3 class in 2025.

The PETN is the only Porsche one-make series on the Nordschleife and is being held as part of the Nürburgring Langstrecken-Serie (NLS). In a field of over 100 cars and severall classes the Cup 2 and Cup 3 class are the biggest and most competative ones. Up to 33 cars compete in the PETN, fighting for position as they are chased from behind by GT3 cars and must overtake cars in slower classes.
