For 2026, the GT2 European Series will reduce the number of rounds from 5 to 6. In contrast to 2025, the series will race at the Monza Circuit for the season opener and at the Algarve International Circuit to finish the season, which returns to SRO competition. Circuit Ricardo Tormo has also been dropped, but the championship will return to Circuit de Spa-Francorchamps, Misano World Circuit and Circuit Zandvoort. [3]
