The No. 31 Cadillac Whelen V-Series.R of Jack Aitken, Earl Bamber and Frederik Vesti held on to win the 28th Motul Petit Le Mans at Michelin Raceway Road Atlanta, closing the 2025 IMSA WeatherTech SportsCar Championship with back-to-back wins in GTP.
Porsche Penske Motorsport drivers Mathieu Jaminet and Matt Campbell finished third to clinch the 2025 GTP drivers’ championship in the No. 6 Porsche 963, accompanied by relief driver Laurens Vanthoor, who drove both factory Porsches after Julien Andlauer withdrew before the race due to back pain.
The No. 6 Penske Porsche won the GTP teams’ championship while Porsche won the manufacturers’ title. Porsche defended every GTP title successfully, including the Michelin Endurance Cup, which went to the No. 7 Penske Porsche (Felipe Nasr/Nick Tandy/Laurens Vanthoor) that came home in tenth after a late incident.
Bamber held off Campbell and then Jaminet for most of the final two hours, but the No. 31 Cadillac and No. 6 Porsche needed a splash of fuel to reach the finish with 15 minutes to go. It put the No. 63 Lamborghini Squadra Corse SC63 (Romain Grosjean/Edoardo Mortara/Daniil Kvyat) into second place, and the No. 23 Aston Martin THOR Team Valkyrie (Ross Gunn/Roman de Angelis/Alex Riberas) into third, on the cusp of fairytale results.
The Lamborghini didn’t have enough energy to capture a maiden podium in the SC63’s final race, but by topping off its tank with 52 minutes left, de Angelis was able to capture the Valkyrie’s first IMSA podium, crossing the finish line in second. Grosjean finished fourth, one position behind Jaminet.
Completing the top five was the polesitting No. 60 Acura Meyer Shank Racing ARX-06 (Tom Blomqvist/Colin Braun/Scott Dixon).
LMP2 was won by the No. 11 TDS Racing ORECA 07-Gibson of Steven Thomas, Mikkel Jensen, and Hunter McElrea, thanks to a huge fuel save in the final stint from Jensen.
The No. 43 Inter Europol Competition ORECA (Jeremy Clarke/Tom Dillmann/Bijoy Garg) recovered from an early incident to finish second, holding off the third-pl ace No. 18 Era Motorsport ORECA (Tobias Lütke/Oliver Jarvis/David Heinemeier Hansson).
Sixth place for the No. 99 AO Racing ORECA of PJ Hyett, Dane Cameron and Jonny Edgar was enough for “Spike the LMP2 Dragon” to win the LMP2 Championship – Hyett’s first in IMSA competition and Cameron’s fifth IMSA title in five different categories.
Race winners Thomas, Jensen and McElrea took the LMP2 Endurance Cup for TDS Racing, on a tiebreak with their second endurance victory, over the Inter Europol Competition crew.
Dan Harper, Max Hesse and Connor De Phillippi won GTD PRO in the No. 48 Paul Miller Racing BMW M4 GT3 EVO after a commanding performance for most of the race.
Corvette Racing by Pratt Miller Motorsports’ Antonio García and Alexander Sims clinched the IMSA WeatherTech GTD PRO Championship in their No. 3 Chevrolet Corvette Z06 GT3.R, finishing third with co-driver Daniel Juncadella. Ahead of them was the sister No. 4 Corvette (Tommy Milner/Nicky Catsburg/Nico Varrone) in second.
It’s García’s sixth IMSA Championship as a Corvette Racing factory driver and fifth since the reunification of American sports car racing. Chevrolet also clinched the GTD PRO manufacturers’ championship.
Harper clinched the win for Paul Miller’s No. 48 BMW by overtaking Catsburg with a little over an hour to go. He and Hesse won the Michelin Endurance Cup title as BMW and Paul Miller Racing swept all three categories.
Two costly penalties and another collision in the last few hours of the race ultimately cost Albert Costa and DragonSpeed a chance at an upset championship triumph. Costa, Davide Rigon and Giacomo Altoè finished seventh in class in their No. 81 Ferrari 296 GT3 after a brutal finish to their race.
Ferrari did get a 1-2 finish in GTD, though, led by a dominating victory for the No. 21 AF Corse Ferrari 296 GT3 of Simon Mann, Alessandro Pier Guidi and Lilou Wadoux.
The No. 023 Triarsi Competizione Ferrari (Onofrio Triarsi/Kenton Koch/James Calado) finished second after leading briefly in the last two hours. Silver-graded Mann stuck with Le Mans overall winner Calado, and after both cars made their final stops, fellow Le Mans winner Pier Guidi retook the lead and held off his WEC co-driver for the win.
AF Corse also took the Michelin Endurance Cup title with their victory at Road Atlanta.
Completing the GTD podium was the No. 12 Vasser Sullivan Racing Lexus (Parker Thompson/Ben Barnicoat/Frankie Montecalvo) in third, ahead of the No. 27 Heart of Racing Team Aston Martin Vantage GT3.
The No. 57 Winward Racing Mercedes-AMG GT3 (Russell Ward/Philip Ellis/Indy Dontje) clinched the IMSA WeatherTech GTD title at the very beginning of the race due to a five-car crash on the opening lap. Ten hours later, Ward and Ellis, with Dontje, completed their back-to-back title-winning season with a fifth-place run and clinched the manufacturers’ title in GTD for Mercedes.
