Heinrich's Porsche Title Bid Survives Indy — but He Needs a Miracle at Petit Le Mans
Third place at Indianapolis keeps the Porsche driver mathematically alive in the GTP fight, but the 147-point gap to Jack Aitken demands a near-perfect Petit Le Mans.
Laurin Heinrich's IMSA GTP title bid survived Sunday's race at Indianapolis Motor Speedway, but the math is now brutal. The Porsche factory driver finished third, one spot behind the championship-leading Cadillac, and heads to the season finale 147 points behind Jack Aitken.
Heinrich shared the No. 6 Porsche Penske Motorsport 963 with Kevin Estre, returning to the factory team one round early after spending much of the 2026 season in JDC-Miller MotorSports' customer car. The pair ran inside the top five for the full two-hour, 40-minute race, which Porsche says included surviving a first-corner incident on the opening lap that put the sister No. 7 car in the garage for 22 laps.
Up front, the race produced a milestone result. BMW M Team WRT scored its first win in IMSA's top class, with Sheldon van der Linde using traffic to get past Earl Bamber's No. 31 Cadillac for the lead with less than six minutes remaining. Bamber and Aitken still banked second place, and that was enough to stretch the No. 31's championship advantage.
The advantage is what makes Heinrich's task so steep. IMSA pays 350 points for a race win and 35 for pole position, while a car that qualifies and finishes last still collects around 220, so the biggest realistic one-race swing is about 165 points. Trailing by 147, Heinrich essentially needs a maximum-score weekend at Petit Le Mans while the No. 31 finishes at the back of the field.
The trajectory of the fight hasn't helped. Aitken led by 203 points heading into August's Road America round; a chaotic race there cut the gap to 118, but the Cadillac's runner-up finish at Indianapolis pushed it back out to 147 with one event left.
Porsche's customer entries had a quieter day. The JDC-Miller 963, the car Heinrich normally races, finished ninth with Tijmen van der Helm and Nico Müller sharing driving duties, while Wright Motorsports' 911 GT3 R was the best of the brand's GT runners in sixth in the GTD class.

The finale, the 10-hour Petit Le Mans at Michelin Raceway Road Atlanta, runs on October 3. Porsche says its manufacturer title hopes also remain alive, though the driver fight will decide whether the season ends in an upset or a Cadillac coronation.
