The Stuttgart-based manufacturer’s factory team will enter two Porsche 963 prototypes in the ten-hour “Petit Le Mans”. In the drivers’ standings, overall leaders Matt Campbell (Australia) and Mathieu Jaminet (France) start as the favourites. Their teammates Felipe Nasr (Brazil) and Nick Tandy (UK), currently second in the table, also remain in contention for the title.
The preview
Heading into the season finale at Road Atlanta, the fight for the manufacturers’ crown is on a knife-edge. Porsche tops the standings with four victories but holds only a seven-point advantage over Acura, Honda’s American performance brand. With 350 points awarded for a race win and 35 for pole position, every session could prove decisive.
“We will give absolutely everything at Road Atlanta to defend all titles,” states Thomas Laudenbach, Vice President Porsche Motorsport. “After our extraordinary start with four wins in a row, the circumstances prevented further victories. The six-hour race at Indianapolis didn’t go as planned. We know we have the potential – now it’s about executing flawlessly. The team is fully focused on the ‘Petit Le Mans’. I’m confident we can emerge from the big finale as winners.”
“We need to deliver maximum performance in all areas to achieve our dream of title defence,” explains Urs Kuratle, Director Factory Motorsport LMDh. “The team, the drivers, and above all the Porsche 963 bring everything needed for another triumph. Since the start of the LMDh regulations in 2023, the 963 has been the most successful car by far – eleven wins in IMSA, more than any rival. At Road Atlanta, we’re targeting win number twelve and, just like last year, all the championship titles.”
“Petit LeMans is the final round of the 2025 IMSA season and is one of the most difficult. The tight confines of the Road Atlanta circuit and the high car count is a recipe for non-stop action,” states Jonathan Diuguid, Managing Director Porsche Penske Motorsport. “Porsche Penske Motorsport is entering the race leading all championships; however, we are not taking anything for granted. Both of our cars have had a strong 8 previous races but it will all be decided in Atlanta and we must stay focused and hopefully rewarded when the checkered flag falls.”
For the endurance classic at the 4.088-kilometer Road Atlanta circuit near Braselton, Porsche Penske Motorsport will once again field three drivers per car. Jaminet and Campbell will share the #6 Porsche 963 with Frenchman Julien Andlauer, while the #7 sister car will be driven by Nasr, Tandy, and Belgian Laurens Vanthoor. JDC-Miller MotorSports enters its 485 kW (659 PS) strong #85 Porsche 963 with Tijmen van der Helm (Netherlands), Max Esterson (USA), and Neel Jani (Switzerland). Proton Competition will not contest the finale.
Championship scenarios: thrilling title fight goes down to the wire
In the drivers’ championship, three duos still have a mathematical shot: Campbell/Jaminet lead with 2,582 points ahead of Nasr/Tandy on 2,451. BMW’s Dries Vanthoor (Belgium) and Philipp Eng (Austria) are third, 145 points adrift. The equation is simple: a seventh-place finish is enough for Campbell/Jaminet to secure the drivers’ crown. The same scenario applies to the teams’ championship.
The manufacturers’ title fight is even tighter: with just a seven-point lead, at least one Porsche 963 must finish ahead of the best-placed Acura to secure the title. In the IMSA Michelin Endurance Cup – the special classification for the long-distance races at Daytona, Sebring, Watkins Glen, Indianapolis, and Road Atlanta – Porsche also leads across the board. In 2024, Porsche swept all titles in this sub-championship as well.
GT classes: Wright Motorsports fights for IMSA Michelin Endurance Cup
After finishing second at Indianapolis, Wright Motorsports still has a shot at the Endurance Cup. The Ohio-based customer team fields a Porsche 911 GT3 R in the GTD class, driven by Americans Adam Adelson and Elliott Skeer alongside Australia’s Tom Sargent in the #120 entry.
In GTD Pro, AO Racing is chasing a third win of the season with its fan-favorite “Rexy” Porsche 911 GT3 R. The #77 will be shared by Laurin Heinrich (Germany), Klaus Bachler (Austria), and Porsche factory driver Michael Christensen (Denmark) – all three former Porsche Juniors.
The race
The “Petit Le Mans”, part of the IMSA calendar since 1998, is one of North America’s most prestigious endurance races. The 28th running will again be held at Michelin Raceway Road Atlanta, about 80 km northeast of Atlanta, home of Porsche Cars North America. The 10-hour race on the undulating 4.088 km natural-terrain circuit, with its twelve corners including the famous fast downhill “Esses” is highly popular among both fans and drivers. Autumn weather in Georgia can bring blazing sunshine, heavy rain, or even thunderstorms.
Porsche’s greatest Road Atlanta triumph came in 2015 in torrential rain, when Nick Tandy, Patrick Pilet (France), and Richard Lietz (Austria) claimed overall victory with the Porsche 911 RSR ahead of all quicker prototype cars – the brand’s only outright win at Road Atlanta to date. Across the “Petit Le Mans”, Porsche has also celebrated 24 class victories.

Driver quotes
Matt Campbell (Porsche 963 #6): “This is it! ‘Petit Le Mans’ is the perfect stage for a big season finale. For me, it’s the best event of the year. Hopefully we can celebrate a successful end to the season. Together with our teammates in the #7, we’re fighting for the championship – it’s going to be thrilling!”
Felipe Nasr (Porsche 963 #7): “Here we are, entering the final race of the season. Road Atlanta always delivers a thriller, and I enjoy the unique challenges this race brings. I’m eager to fight for the manufacturers’ championship with Porsche, that’s our main goal. I’m excited to team up with Nick Tandy and Laurens Vanthoor again, and hopefully we pick up right where we left off in Sebring!”
Neel Jani (Porsche 963 #85): “It’s a shame Proton Competition can’t be there, so I’m really pleased to join JDC-Miller MotorSports at Road Atlanta. We may be outsiders, but anything can happen at ‘Petit Le Mans’. The team tested here recently, so the car should be well-prepared. I know the circuit very well and have already won here twice. In 2023, Proton and I even managed a podium with the Porsche 963. We’ve got a shot!”
Laurin Heinrich (Porsche 911 GT3 R #77): “The mood is a bit subdued since we lost our chance to defend the title at Indianapolis. But I’m fired up for Road Atlanta: I’ve got unfinished business there. In 2024, we secured the championship but suffered a tough race on Saturday after leading early. Now I want to win the ‘Petit Le Mans’ – it’s high on my wish list and a huge motivation. We’ll give everything to celebrate another win with ‘Rexy’.”
