• LMPC: The Oreca FLM09 in the LMPC class saw strong participation, with CORE Autosport winning the team championship.

How It Works

The ALMS operated on a multi-class endurance racing format, where different vehicle types competed simultaneously under performance-based balancing rules. Each race tested reliability, fuel efficiency, and team coordination over long distances.

• LMP1:Le Mans Prototype 1 featured factory or near-factory cars like the HPD ARX-03a, with unrestricted aerodynamics and high power outputs exceeding 600 hp.
• LMP2:Le Mans Prototype 2 used spec engines and cost-capped chassis, such as the HPD ARX-01g, limited to 550 hp for closer competition.
• LMPC:Le Mans Prototype Challenge used identical Oreca FLM09 chassis with Chevrolet V8 engines, ensuring parity among privateer teams.
• GT:Grand Touring class included modified production-based cars like the Chevrolet Corvette C6.R and Porsche 911 GT3 RSR, with strict performance windows.
• GTC:GT Challenge featured entry-level GT cars such as the Porsche 911 GT3 Cup, aimed at developing drivers and smaller teams.
• Endurance Format: Races lasted between 2.5 hours and 12 hours, requiring multiple drivers, pit stops, and strategic fuel and tire management.
