ADAC GT Masters – Hockenheimring: Owega and Wiebelhaus Crowned Champions

Race 1

Salman Owega and Finn Wiebelhaus sealed the 2025 ADAC GT Masters title on Saturday at the Hockenheimring, bringing Ford its first-ever championship in the series. Ninth place in the wet opener was enough for the Haupt Racing Team duo in the Mustang GT3 to wrap up the title with one race to spare, as rivals Leyton Fourie and Tim Zimmermann could only manage 13th.

Victory went to Nico Hantke and Denis Bulatov in the Scherer Sport PHX Audi R8 LMS GT3 Evo 2, ahead of Simon Birch and Leo Pichler’s Porsche 911 GT3 R. Alexander Fach and Alexander Schwarzer completed the podium, securing the Pro-Am Cup for the second year in a row. Haupt Racing Team also claimed its third consecutive teams’ title—the first outfit ever to achieve that feat.

Race 2

Having already clinched the championship, Owega and Wiebelhaus ended their season on a high with a commanding victory in Sunday’s finale. Wiebelhaus charged through the field in the second stint, overtaking Alexander Schwarzer and Tim Zimmermann to claim the win by 1.7 seconds.

Fourie and Zimmermann finished second in their FK Performance BMW M4 GT3, securing the runner-up spot in the standings, while Hantke and Bulatov followed up Saturday’s triumph with third place. Fach and Schwarzer again took Pro-AM honours in fourth, while the Holzem twins completed the top five for Schubert Motorsport.

British GT Championship – Donington Park: 2 Seas and Optimum Crowned 2025 Champions

GT3

Charles Dawson and Kiern Jewiss clinched the 2025 British GT Championship for 2 Seas Motorsport after a tense, weather-affected finale at Donington Park. Despite a collision and a time penalty, the Mercedes-AMG GT3 crew finished fourth, enough to secure the title. Race victory went to Sandy Mitchell and Alex Martin in the Barwell Lamborghini Huracán GT3 Evo2 after a bold strategy call to stay on slicks during heavy rain paid off.

GT4

Jack Brown and Marc Warren delivered a superb comeback to win both the race and the GT4 championship for Optimum Motorsport. The McLaren Artura duo overcame a pit stop handicap and changing weather to snatch the lead in the closing laps, making Brown the first driver to defend a British GT4 title. Charlie Robertson and Ravi Ramyead finished behind in the Century BMW after a hard-fought battle, with Mahiki’s Luke Garlick and Blake Angliss completing the podium.
