McLaren has officially revealed the MCL-HY hypercar that will contest the World Endurance Championship and the Le Mans 24 Hours from 2027, alongside the track car variant MCL-HY GTR, which will be offered to VIP clients through its exclusive Project: Endurance program.
Built to the LMDh regulations, the MCL-HY features a Dallara chassis and is powered by a twin-turbocharged V6 race engine, developed in conjunction with Autotecnica Motori and paired with the series’s spec MGU system, delivering up to 520kW (707ps) to the rear axle. Minimum weight is set at 1,030kg.
The car was presented in a 2026 test livery inspired by the McLaren M6A, nodding to the lineage that stretches from Can-Am dominance in the late 1960s through to outright Le Mans victory with the F1 GTR in 1995. On-track testing begins this month, with works driver Mikkel Jensen joined by DDP drivers Grégoire Saucy and Richard Verschoor, plus United Autosports development driver Ben Hanley.
According to the team, the program also marks a first-of-its-kind collaboration between McLaren Racing and McLaren Automotive – the GTR track car derivative is powered by the same 2.9-liter twin-turbocharged engine but without the LMDh hybrid system, producing around 730ps at a lower dry weight. Deliveries are scheduled for late 2027.
Homologation of the MCL-HY is expected in winter 2026 ahead of the team’s WEC debut.
