McLaren has unveiled its new MCL-HY Hypercar, confirming its return to the top class of endurance racing at the 24 Hours of Le Mans in 2027 and the FIA World Endurance Championship (WEC).

The reveal marks a significant step in the British marque’s long-term motorsport ambitions, with the new car forming part of a broader push to compete across Formula 1, IndyCar and endurance racing simultaneously.

Developed to LMDh regulations, the MCL-HY combines a lightweight carbon-fibre chassis with a hybrid powertrain built around a twin-turbocharged V6 engine. Total output is capped at around 520kW, in line with class regulations, with power delivered to the rear wheels.

The car will undergo an extensive testing programme throughout 2026 ahead of homologation, with McLaren drawing on both its racing division and automotive arm to shape the final design and performance package.

McLaren’s return to Le Mans’ top category is its first since its famous outright victory in 1995 with the F1 GTR. The move also completes its presence across motorsport’s three most prominent arenas, aligning with its long-held ambition to compete for the so-called Triple Crown – wins at Monaco, Indianapolis and Le Mans.

Alongside the race car, McLaren has also revealed a track-only derivative, the MCL-HY GTR, aimed at a small number of private buyers. Unlike the race version, it drops the hybrid system and relies solely on a twin-turbo V6 producing around 730PS, while also benefiting from a lower weight.

The GTR forms part of a broader customer programme dubbed Project: Endurance, which includes access to McLaren’s race team operations and a two-year track driving schedule across international circuits.

McLaren says deliveries of the track car will begin in late 2027, coinciding with its competitive debut in the WEC.
