For this season, the GT2 European Series will switch to Pirelli's new P Zero DHG tyres, as the SRO Motorsports Group adopts these for all its GT2, GT3 and GT4 championships in 2025. They feature FSC-certified natural rubber. The DHG replaces the DHF, which has been used globally for three years. It includes a wider working range and optimised construction for better grip and uniformity. Pirelli, SRO’s exclusive tyre supplier since 2013, will continue its partnership until at least 2028.[2]
The race lengths have also been extended from 50 minutes per race to 60 minutes per race. This provides drivers with an additional 20 minutes of racing time each weekend.[3]
In the Pro-Am category, DINAMIC Motorsport makes a full-season entry into the championship; the No. 7 Maserati will be driven by Italian Roberto Pampanini and Swiss racer Mauro Calamia throughout all rounds in 2025.[3] Mičánek Motorsport, powered by Buggyra, made there debut in the series in 2025, competing in the Pro-Am category with Bronek Formanek and Stefan Rosina piloting the No. 11 Lamborghini.[6] RTR Projects also field a full-season Pro-Am KTM entry piloted by Mato Homola at all rounds.[6] Finally, NM Racing Team enter a full-season Spanish Mercedes entry with Alberto De Martin and Nil Montserrat set to race the full year.[6]

In the opening race at Circuit Paul Ricard, Mičánek Motorsport, powered by Buggyra, claimed a debut Pro-Am victory thanks to a flawless drive by Bronek Formanek and Štefan Rosina in the No. 11 Lamborghini. After early battles and a pit-stop shuffle, Rosina took the lead and pulled away to win. The No. 80 KTM of Birch/Andersen finished second, with Montserrat/de Martin's Mercedes-AMG in third. In the Am class, Philippe Prette held off late pressure to win, with Bourret/Gibon finishing second and Freymuth third. In the second race of the opening weekend, Mičánek Motorsport, powered by Buggyra, dominated again, winning the Pro-Am class in challenging wet conditions. Rosina started from pole in the No. 11 Lamborghini. He handed over to Formanek, who extended the lead to win by nearly 40 seconds. NM Racing Team’s No. 115 Mercedes-AMG and DINAMIC Motorsport’s No. 7 Maserati completed the Pro-Am podium. Freymuth won comfortably in the No. 24 AKF Motorsport Lamborghini in the Am class. Mercedes-AMG also secured a double Am podium, while a collision caused by Prette affected the RTR Projects team, leading to a penalty but a fourth-place recovery.[12]
Prette secured a stunning Race 1 win at Zandvoort, narrowly defeating Rosina by less than a second. Starting from pole in the No. 1 Maserati, Prette overcame a crash-related repair job. He dominated the first stint and, after a mid-race pit stop, fended off Rosina—who had taken the Pro-Am leading No. 11 Lamborghini from Formanek. Prette became the first Am driver to win outright since 2022, while Rosina earned the Pro-Am win, marking his team’s third straight victory. The No. 7 DINAMIC Motorsport Maserati finished third overall and second in Pro-Am after a strong performance despite a delayed pit stop. Further back, Mato Homola brought the No. 89 RTR Projects KTM to third in Pro-Am, showcasing impressive teamwork after a qualifying crash. In the Am class, the No. 294 RTR Projects Mercedes-AMG and No. 53 AKKODIS ASP Mercedes-AMG rounded out the podium behind Prette. Roberto Pampanini and Mauro Calamia achieved their first win of 2025 in a competitive Pro-Am Race 2. Calamia, driving the DINAMIC Motorsport Maserati, claimed second early and stayed close to the leading No. 11 Lamborghini of Rosina. Despite having three seconds less compensation time during pit stops, the Maserati remained behind the Lamborghini. Pampanini capitalised with just over two minutes remaining, overtaking Formanek in traffic at Tarzan corner to take the lead and secure victory—marking his and Calamia’s second career GT2 Europe win. Rosina and Formanek finished second, with the NM Racing Team Mercedes-AMG taking third in Pro-Am. In the Am class, Prette dominated, winning again in the No. 1 Maserati, finishing third overall and over a minute ahead of his nearest rival. The AKKODIS ASP Mercedes-AMG took second in Am after Pascal Gibon passed the RTR Projects car on the last lap.[13]
Formanek and Rosina won their fourth Pro-Am of the season at Spa-Francorchamps, strengthening their lead. Starting from pole, Formanek led despite light rain, but the team received a 13-second penalty for an early pit stop. Rosina rejoined with a strong gap, holding off Calamia to win despite the penalty. Calamia and Pampanini finished second; Homola took third, earning debutant Davit Kajaia a podium. In the Am class, Prette secured his fourth win, ahead of Freymuth and the AKKODIS ASP duo, their fifth straight podium. Formanek and Rosina’s fifth Pro-Am win out of six came despite a formation lap penalty and a 10-second pit stop hold. Rosina built a lead; Formanek passed Kajaia at Les Combes for the win. Kajaia and Homola finished second, with the No. 7 Maserati third. In the Am class, Prette’s lead ended after a long pit stop, leading to a battle between the No. 53 AKKODIS ASP Mercedes-AMG and Petr Lisa’s No. 789 KTM. A last-minute error from Gibon gave Lisa and Viktor Mraz their first win, with Freymuth third and Prette fourth.
