24 Hours of Le Mans 2025

The 2025 24 Hours of Le Mans represented a major milestone for Action Express Racing, as the team fielded the No. 311 Cadillac V-Series.R as part of Cadillac Racing’s four-car factory Hypercar effort at the legendary Circuit de la Sarthe.

Right from qualifying, the No. 311 entry made its presence felt. In Hyperpole 1, Jack Aitken delivered the fastest lap of the session, a statement performance that put the Cadillac at the top of the Hypercar timing screens and firmly into the Hyperpole shootout. Against the full strength of the FIA World Endurance Championship field, that lap underlined both the outright pace of the Cadillac V-Series.R and the execution capability of the Action Express program on the global stage.

Throughout practice and qualifying, the team refined its low-drag Le Mans configuration, balancing straight-line efficiency along the Mulsanne with stability through the high-commitment Porsche Curves. The Hyperpole result validated the work done in preparation and positioned the No. 311 squarely among the front-running contenders heading into the 24-hour race.

Once the marathon began, the Cadillac settled into a disciplined and competitive rhythm. As daylight faded into night, the crew executed clean pit sequences, managed tire and energy strategy with precision, and navigated multi-class traffic with authority. The No. 311 remained firmly in the fight through the crucial overnight hours, demonstrating both durability and consistent pace.

Competing as one of four factory Cadillacs, Action Express Racing carried significant responsibility within the wider Cadillac Racing campaign — and delivered a performance worthy of that platform. From setting the benchmark in Hyperpole 1 to executing across 24 demanding hours, the No. 311 effort reinforced the strength, depth and international credibility of the No. 31/311 program.
