Cadillac Wins Motul Petit Le Mans as Champions Crowned
Thrilling Finish to 28th Annual Event to Cap Off 2025 IMSA WeatherTech Championship Season
Cadillac has gone back-to-back at the Motul Petit Le Mans to conclude the 2025 IMSA WeatherTech SportsCar Championship season at Michelin Raceway Road Atlanta.
With an authoritative drive, the trio of Jack Aitken, Earl Bamber and Frederik Vesti scored their second straight Grand Touring Prototype (GTP) and overall victory in their No. 31 Cadillac Whelen Cadillac V-Series.R. The same trio won the TireRack.com Battle On The Bricks at the Indianapolis Motor Speedway.
Cadillac also won last year’s Motul Petit Le Mans in the hands of the Chip Ganassi Racing-prepared, Cadillac Racing-branded No. 01 entry.
The win came amidst a flurry of final pit stops within the half hour of the 10-hour race, as teams topped off their energy tanks to make the finish. The No. 31 Cadillac led most of the race but needed a final topper to ensure the victory, and then emerged ahead of the trailing pack to secure the win.
In second, the Aston Martin THOR Team scored the best finish for the new No. 23 Aston Martin Valkyrie globally with the trio of Roman De Angelis, Ross Gunn and Alex Riberas.
GTP champions Matt Campbell and Mathieu Jaminet finished third in the race aboard the No. 6 Porsche Penske Motorsport Porsche 963, in the car they shared with Laurens Vanthoor. The result also sealed Porsche the GTP manufacturer championship. It’s the second consecutive GTP championship for the Porsche Penske Motorsport team and second in IMSA for both Campbell and Jaminet, who won the first Grand Touring Daytona Pro (GTD PRO) in 2022 aboard a Pfaff Motorsports Porsche.
“This championship is a testament to the entire Porsche Penske Motorsport team and the hard work and dedication they invest into this program every day,” said Roger Penske, Founder and Chairman Penske Corporation. “The season started with four consecutive victories, including back-to-back (Rolex) 24 Hours of Daytona wins, and has continued into 10 total podiums. That type of success isn’t accomplished without great drivers, leaders and a resilient crew. The commitment to winning together has been unwavering and defending the IMSA WeatherTech SportsCar Championship title is reflection of those efforts from all the men and women across both Mooresville and Germany.”
