Motul Petit Le Mans 2025

At the season-defining Petit Le Mans, the No. 31 Whelen Cadillac delivered exactly the kind of performance that defines Action Express Racing – disciplined, resilient and relentlessly competitive.

Competing in the final round of the 2025 IMSA WeatherTech SportsCar Championship, the No. 31 Cadillac V-Series.R driven by Jack Aitken, Earl Bamber and Frederik Vesti executed a near-flawless 10-hour race at Michelin Raceway Road Atlanta. From the opening stint, the car showed strong balance and long-run pace, allowing the team to control strategy rather than react to it.

Through traffic, full-course cautions and the transition from daylight to darkness, the crew maintained composure and precision. Pit stops were consistently clean, strategy calls were assertive but measured, and the drivers managed traffic with authority in the closing hours. When the race entered its decisive phase, the No. 31 had the pace in hand – stretching its advantage and closing out the event with confidence.

Importantly, this marked the first Petit Le Mans victory for the No. 31 Action Express entry in the GTP era, a milestone result for the program. It also capped a powerful late-season surge, coming immediately after the team’s win at the Indianapolis round – the Battle on the Bricks – giving the No. 31 squad back-to-back victories to finish the championship.

While endurance racing always presents its challenges, the focus remains on execution – and at Road Atlanta, the team delivered at every level. The result underscores the strength of the Cadillac package, the depth of engineering within Action Express Racing, and the quality of the driver lineup.

Ending the season with consecutive wins sends a clear message: the No. 31 program carries championship-level momentum and is firmly positioned for continued success in the seasons ahead.
