McLaren MCL-HY: The Le Mans Hypercar and the Track Car You Can Actually Own

The McLaren MCL-HY is the car that takes McLaren back to Le Mans for the first time since the F1 GTR won it outright in 1995. Built to LMDh regulations for the 2027 FIA World Endurance Championship, the McLaren MCL-HY pairs a twin-turbocharged 2.9-litre V6 race engine with a hybrid MGU system delivering up to 520 kilowatts (707 PS) to the rear axle through a carbon fibre monocoque chassis that weighs a minimum of 1,030 kilograms.

The test livery — a searing papaya orange inspired by the McLaren M6A that Bruce McLaren once dreamed of taking to La Sarthe — is a declaration of intent rooted in six decades of heritage. On-track testing begins this month, with homologation scheduled for winter 2026 and a WEC grid debut in 2027.

Inside the McLaren MCL-HY Powertrain and Chassis

The McLaren MCL-HY has been developed to balance outright performance with endurance racing efficiency at the highest level. The twin-turbo V6 and hybrid MGU system deliver their combined 707 PS exclusively to the rear wheels, and the carbon fibre monocoque from Dallara provides the structural foundation for a power-to-weight ratio that puts the McLaren MCL-HY in direct contention with the Porsche 963, the Toyota GR010 Hybrid, and the Ferrari 499P.

McLaren Racing and McLaren Automotive collaborated on aerodynamics and design integration, embedding McLaren’s design DNA across every surface of the car. Like the Porsche 975 RSE, the MCL-HY marks another step in the shift to electrified hybrid platforms — performance and endurance targets now inseparable from powertrain architecture. The Dallara partnership provides the structural carbon fibre expertise; McLaren brings the design and homologation authority.

The McLaren MCL-HY GTR: A 730-PS Track Car Without the Hybrid

The McLaren MCL-HY GTR is the track-only derivative — engineered in parallel with the race car but deliberately stripped of the mandated LMDh hybrid system. Powered by the 2.9-litre twin-turbo V6 alone, the McLaren MCL-HY GTR produces approximately 730 PS at a dry weight below the race car’s 1,030-kilogram minimum — lighter and more powerful than the version competing for points. McLaren calls it a purer driving experience: Hypercar performance without hybrid management complexity.

Between 30 and 35 units will be built for select VIP clients, with deliveries beginning late 2027. The Xtrac seven-speed sequential gearbox and carbon-carbon disc brakes carry over directly from the race car, with ABS replacing the more complex brake-by-wire system and traction control and multiple engine maps added to tailor power delivery for client driving.

Project: Endurance and the Triple Crown Ambition Behind the McLaren MCL-HY

Ownership of the McLaren MCL-HY GTR extends far beyond the car itself. Project: Endurance is the exclusive programme that immerses clients in McLaren Racing’s WEC operation — pit access, VIP hospitality, and behind-the-scenes insight direct from the Hypercar Team. GTR owners participate in a two-year, six-event track programme across premier international circuits, with professional driver coaching, a dedicated pit crew, and race engineering support on a fully inclusive arrive-and-drive basis.

The McLaren MCL-HY completes the final piece of McLaren’s Triple Crown ambition — victory at the Monaco Grand Prix, the Indianapolis 500, and the 24 Hours of Le Mans. With McLaren already competing at the pinnacle of Formula 1 and IndyCar, the McLaren MCL-HY makes McLaren the only team contending for all three simultaneously. Mikkel Jensen leads the 2026 test programme as works driver alongside McLaren DDP drivers Grégoire Saucy and Richard Verschoor.

The McLaren MCL-HY enters development wearing the papaya orange that has defined McLaren since 1967, and its WEC debut will mark the first time in over three decades that a McLaren has contested the outright classification at Le Mans. Applications for Project: Endurance are now open, with deliveries targeting the 2027 WEC season.
