With a clear focus on sustainability, Manthey is taking to the Nürburgring-Nordschleife in 2026 with an enhanced version of the Porsche 911 GT3 Cup. The car will make its racing debut at the third round of the Nürburgring Endurance Series (NLS) and will later also be entered in the 24-hour race. There is a particular focus on the use of synthetic fuel and components made from recycled materials.
After a successful 2025 season, which included a top 20 finish in the 24-hour race, Manthey and the Griesemann Group are continuing their collaboration. In the anniversary year of both partners, a specially developed vehicle concept is once again being created. The new racing car is based on the 992.1 generation of the 911 GT3 Cup and has been specifically developed for use on the Nordschleife.
Familiar names will take turns in the cockpit: Björn Griesemann, Georg Griesemann, Dirk Adorf and Marco Holzer share the car with the starting number 992. The drivers were able to gain extensive experience on the Nordschleife last year and were competitive both in their class and in the overall field.
In technical terms, Manthey relies on a comprehensively revised aerodynamics and cooling system. Numerous components – including the front section, fenders, rear panel and rear wing – are made from recycled carbon fiber composite (CFRP). In addition, an existing chassis is deliberately used in order to conserve resources. A centrally positioned radiator not only improves temperature control, but also reduces the risk of damage in the event of racing incidents. In addition, brake cooling and aerodynamics have been further optimized, including through new add-on parts and a modified air flow.
The chassis has also been modified: Widened wheel arches enable a wider track width, while a new lightweight wheel set saves additional weight. A closed tank system has also been integrated for long-distance use, allowing refueling via the front hood.
A central element of the project is the use of eFuel. The racing car will run entirely on the synthetic fuel “eFuel Race 98”, which is being developed as part of a research project at the TU Bergakademie Freiberg. The fuel is based on eMethanol, which is produced using green hydrogen, and can be used in conventional combustion engines without any technical modifications. Accordingly, the vehicle is competing in the category for alternative fuels.
In addition to the 24-hour race at the Nürburgring in mid-May, there are other events on the program beforehand, including NLS races and qualifying races. A special highlight: During the race, Dirk Adorf will commentate live on parts of the drive and provide insights directly from the cockpit.
Manthey sees the project as a successful combination of motorsport and innovation. The aim is to combine high-performance racing technology with sustainable approaches and thus provide new impetus. The Griesemann Group also emphasizes that synthetic fuels could play an important role in the future – especially when it comes to making existing technologies more climate-friendly.
