The 2025 IMSA WeatherTech SportsCar Championship saw Porsche Penske Motorsport and the iconic Porsche 963 dominate in the GTP class, once again cementing the brand’s position at the pinnacle of endurance racing. The team claimed every major title in GTP, marking another chapter of triumph for Porsche.
Vice-President of Porsche Motorsport, Thomas Laudenbach, praised the team’s spirit and adaptability: “Our team showed incredible spirit and extracted the maximum possible from every situation. I’m immensely proud of that.”
Founder and Chairman of Penske Corporation, Roger Penske, remarked on the milestone: “Winning the 24 Hours of Daytona two times in a row along with the other key races and back-to-back IMSA championships wouldn’t have happened without the hard work and long hours by the men and women on our team.”
A season of high points
The campaign kicked off with a landmark moment: at the 24 Hours of Daytona 2025, the No. 7 Porsche 963, driven by Felipe Nasr, Laurens Vanthoor and Nick Tandy, took overall victory — marking Porsche’s 20th win in the event. Meanwhile, their sister car finished on the podium in third place. From that point, Porsche never relinquished its grip on the manufacturers’ championship standings.
At the 12 Hours of Sebring, Porsche followed with another dominant performance: Nasr, Tandy and Vanthoor clinched yet another win, giving Porsche its 19th overall victory at Sebring. Their teammates Matt Campbell and Mathieu Jaminet were second, resulting in a Porsche 1-2 finish.
Penske’s precision strategy also shone at the Long Beach Grand Prix 2025. Amid the event’s 50th anniversary, lightning-fast pit stop work and flawless execution delivered yet another 1-2 finish for Porsche.
At Laguna Seca, Porsche once more showed its racing pedigree — Matt Campbell and Mathieu Jaminet finished ahead of Nasr and Tandy in a thrilling showdown, giving Porsche four wins in its first four races of the season.
Challenges and resilience
Not every outing was smooth. At Watkins Glen, the team faced chaos and ultimately recorded its first DNF (Did Not Finish) of the season after a crash in the sister car and a fourth place for Campbell and Jaminet in their car. Yet despite the setback, Porsche retained its championship leads.
The sprint race at Road America turned into a crash-heavy affair, with multiple safety-car periods disrupting strategy. The No. 6 car finished fifth, and the sister car, penalised and delayed, came home 11th.
At Indianapolis, where Penske builds its roots, Porsche had a difficult weekend and still focused on damage control — finishing seventh and 12th. Even so, the team kept its hold on all championship categories.
Triumph at Petit Le Mans
The finale at Petit Le Mans 2025 at Road Atlanta brought everything into focus. Heading into the final race, Campbell and Jaminet held a comfortable drivers’ championship lead, but Porsche’s manufacturers’ crown was only ahead by two points after qualifying. Under pressure, the team delivered: Campbell and Jaminet finished third, sealing all GTP titles.
For the second year in a row Porsche claimed the manufacturers’ trophy, Porsche Penske Motorsport took the team title, and Campbell and Jaminet captured the drivers’ championship in GTP. In the IMSA Michelin Endurance Cup, Nasr and Tandy claimed both the driver and team titles for the No. 7 car, while Porsche secured the manufacturers’ crown.
Looking forward
With nine races, four victories and six additional podiums in the 2025 season, Porsche’s factory programme showed not just speed — but durability, teamwork and strategy.
