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 will make 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] Razoon – More Than Racing will return for a second year with the Danish duo of Thomas Anderson and Simon Birch, who previously claimed third place in the Pro-Am standings in 2024; they will compete for the title in car No. 80 KTM.[10] LP Racing will introduce a new lineup for their Pro-Am No. 8 Maserati, with Eddie Cheever III and Anik Patel aiming for the championship. Additionally, Mičánek Motorsport, powered by Buggyra, is set to debut in the series in 2025, competing in the Pro-Am category; Bronek Formanek and Stefan Rosina will pilot the No. 11 Lamborghini.[6]
In the Am Cup, Philippe Prette will return with LP Racing to defend his title in the No. 1 Maserati.[4] AFK Motorsport will enter a full-season Am Lamborghini, driven by Oliver Freymuth in car No. 24.[7] Furthermore, TFT Racing has announced their No. 28 Maserati Am entry, which is scheduled to compete in all rounds of 2025, with Jordan Boison and Patrick Charlaix as the drivers.[8]
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 Philippe Prette affected the RTR Projects team, leading to a penalty but a fourth-place recovery.
