The Prototype Cup Germany will start its second season in Germany and the Netherlands at six events with two races each. Three race weekends are planned at the highly publicised DTM events, including an appearance at the season highlight at the Norisring. The other three race weekends will take place as part of the ADAC Racing Weekends. The races of the Prototype Cup Germany, organised by ADAC and the Dutch agency Creventic, will remain independent; the DTM Endurance concept presented in December will not be pursued further. All races will be available online in the free livestream at adac.de/motorsport and on YouTube.

The season will start from 28 to 30 April at the ADAC Racing Weekend opener in Hockenheim. It continues from 26 to 28 May at the DTM season opener at the Motorsport Arena Oschersleben, and the LMP3 prototypes will also be on the grid at the subsequent DTM guest race in the Netherlands at the Formula 1 circuit of Zandvoort from 23 to 25 June. A highlight follows at the beginning of July: for the first time, the Prototype Cup Germany will be held on a street circuit and will see the prototypes return to the Norisring from 7 to 9 July. For the last time until then, sports cars of this type contested a race in Nuremberg in the ADAC Supercup in 1989. Like the Norisring, Oschersleben and Zandvoort are also new territory for the Cup. From 1 to 3 September, the ADAC Racing Weekend at the TT Circuit Assen in the Netherlands, another new track for the series, will herald the season's final spurt. The finale will take place at the ADAC Racing Weekend from 13 to 15 October at the Grand Prix circuit of the Nürburgring.

In addition to the six race events, an official pre-season test will be offered, which will take place on 22 March 2023 in Mugello / Italy. Entries for the Prototype Cup Germany are now open.
