The inaugural season of the Prototype Cup Germany was announced on 22 December 2021. Four race weekends were confirmed for the opening campaign at Circuit de Spa-Francorchamps, the Nürburgring, the Lausitzring, and the Hockenheimring. The partnership between ADAC, the largest automotive club in Germany and a long-standing organizer of national motorsport championships, and Creventic, the Dutch company best known for running the 24H Series of endurance races, combined organizational reach with prototype-racing expertise.
The series was conceived as a dedicated championship for LMP3-class machinery in Central Europe, offering teams a sprint-format alternative to the longer endurance events that LMP3 cars were more typically associated with. By providing a two-race weekend structure on well-established circuits, the Prototype Cup Germany lowered the logistical barrier to LMP3 competition for German-based operations.
Each race weekend in the Prototype Cup Germany comprised two sprint races, each of 55 minutes duration. A mandatory pit stop was built into the race format, introducing a tactical dimension that required teams to balance tyre management and driver changes within the sprint window. The mandatory stop distinguished the series from a purely sprint format and rewarded well-organized team strategies.
The primary class was for LMP3 prototypes powered by the V8 engines specified under ACO LMP3 regulations. CN cars — a French-derived prototype category — were also eligible to compete alongside the LMP3 machinery. Control tyres were supplied by Michelin throughout the series' four-year existence, providing a common technical baseline across competitors.
The V8 engine specification of the eligible LMP3 cars became central to the series' eventual demise. Negotiations with the Automobile Club de l'Ouest, the governing body for LMP3 homologation, over the future of V8-powered cars reached an impasse after the 2025 season, leading to the decision to fold the championship.
Over its four seasons, the Prototype Cup Germany visited a wide range of European circuits, reflecting both Creventic's international scheduling experience and the desire to offer varied competition. Ten different venues hosted championship rounds between 2022 and 2025:
Circuit de Spa-Francorchamps (2022, 2024–2025)
Nürburgring (2022–2025)
Lausitzring (2022, 2024–2025)
Hockenheimring (2022–2025)
Motorsport Arena Oschersleben (2023)
Circuit Zandvoort (2023–2024)
Norisring (2023, 2025)
TT Circuit Assen (2023)
Sachsenring (2024)
Red Bull Ring (2025)
The Nürburgring and Hockenheimring were the most consistent fixtures, appearing on the calendar every year the series ran, underscoring their position as Germany's two most prominent permanent road-racing circuits. Spa-Francorchamps, the Lausitzring, and the Norisring also became recurring venues. The 2023 season was the most geographically diverse, incorporating Oschersleben, Zandvoort, and Assen alongside the established German venues. The Sachsenring appeared once, in 2024, while the Red Bull Ring in Austria featured on the final 2025 calendar, extending the series' reach into neighboring markets.
Following the 2025 season, ADAC and Creventic confirmed that the Prototype Cup Germany would not continue. The organizers were unable to secure an agreement with the ACO regarding the continuation of the V8-powered LMP3 cars that formed the backbone of the series. Without a clear path forward on the technical regulations, the partnership opted to close the championship rather than reorganize it around a different class. The series ran for exactly four seasons, from 2022 through 2025.
