DAYTONA BEACH, Fla. – Mathieu Jaminet will leave Porsche on a high note at the end of the 2025 calendar year, announcing in a post on social media his intent to “start a new chapter.”
“Danke, Porsche,” Jaminet wrote on Instagram. “After so many unforgettable years together, I’ve chosen to start a new chapter at the end of this WEC season. It’s been one of the hardest decisions of my life, but I felt it was the right time to move on. I’ll never forget what this brand did for me 10 years ago: taking a kid with no backing, no money, just a dream and giving me a chance. To everyone who has been part of this journey teammates, engineers, mechanics, and friends — thank you. We achieved things I once only dreamed of. Finishing with an IMSA championship feels like the perfect goodbye. Now, let’s go to Bahrain and enjoy this last one! #ThankYou”
Porsche added in its farewell post: “Merci @mathieu_jaminet! Following the end of 2025, the Frenchman will be moving on to his next adventure, and we wish him all the best. Mathieu started his career with the brand becoming a Porsche Junior driver in 2016 and has since been crowned Porsche @carreracupfrance Champion (2016), @porschesupercup Rookie Champion (2016), GT Masters Champion (2018), @imsa_racing GTD Pro Champion (2022), and together with @porschepenskemotorsport is the reigning IMSA GTP Champion (2025). Good luck JamJam, see you on track!”
Jaminet wraps a decade with Porsche since being named a “Young Professional” by the manufacturer in 2016, a year when he won the Porsche Carrera Cup France championship. After four years in that role he joined the Porsche factory roster in 2020.
His IMSA career, spanning 52 career starts from 2017 through 2025, has been entirely in Porsche machinery and delivered a wealth of success.
A 12-time race winner in the IMSA WeatherTech SportsCar Championship, Jaminet’s most frequent success came alongside co-driver Matt Campbell. The pair won the 2022 Grand Touring Daytona Pro (GTD PRO) championship in the class’ first season in the No. 9 Pfaff Motorsports Porsche 911 GT3 R, and have now doubled their title-winning success with this year’s Grand Touring Prototype (GTP) championship in the No. 6 Porsche Penske Motorsport Porsche 963. The 2022 season also included a Rolex 24 At Daytona win in GTD PRO, with Felipe Nasr that car’s third driver. This year, Jaminet and Campbell won at WeatherTech Raceway Laguna Seca.
Jaminet was reflective during the weekend at Motul Petit Le Mans when discussing the title after the race:
“I’ve been chasing a success like this for over two years,” he said. “In 2023 and 2024, I gave everything I had, but it just wasn’t enough for a championship title, which was frustrating. That makes winning it now feel even more special. Doing it alongside my mate Matt Campbell makes it even more memorable. Huge thanks to everyone who played a part in this achievement.”
Jaminet’s been part of the Porsche Penske Motorsport entry for each of its 27 starts since the GTP class was introduced in 2023. With his intent to leave, it opens at least one full-time IMSA seat for 2026 as the team prepares to defend its championship and add a third straight title.
Porsche traditionally announces its program and driver lineup for the next year at its year-end celebrations in Germany, which is usually held in late November or early December depending on the way the calendar falls.
The change also means the same top-class title-winning lineup won’t return intact for a sixth consecutive season.
Felipe Nasr and Dane Cameron won in 2024, with Cameron moving on from Porsche Penske Motorsport to then win this year’s Le Mans Prototype 2 (LMP2) title alongside PJ Hyett at AO Racing.
In 2023, it was Pipo Derani and Alexander Sims claiming the crown for Cadillac Whelen in the Action Express Racing-prepared entry. Sims then went to Corvette Racing by Pratt Miller Motorsports in 2024.
Tom Blomqvist and Oliver Jarvis won the final Daytona Prototype international (DPi) title in 2022 with Meyer Shank Racing before Colin Braun returned to that lineup alongside Blomqvist in 2023.
Derani and Nasr won in the No. 31 Cadillac in 2021 before Nasr left to begin the testing and development work for Porsche Penske Motorsport in 2022.
Then in 2020, Ricky Taylor and Helio Castroneves won in the No. 7 Acura Team Penske Acura ARX-05, the last year of that program. Both Taylor and Castroneves headed to Wayne Taylor Racing in 2021 and were part of the Rolex 24 winning lineup.
It’s been since 2020, when Cameron and Juan Pablo Montoya resumed in the No. 6 Acura Team Penske Acura ARX-05, that the same top-class prototype driver pairing has been back to defend as-is from year-to-year after winning the 2019 DPi title.
