McLaren Unveils MCL-HY GTR: More Powerful Customer Twin for Le Mans Without Hybrid System

McLaren has officially unveiled the MCL-HY FIA Hypercar, a new entrant designed to compete in the 2027 World Endurance Championship (WEC). Alongside it, the automaker introduced the MCL-HY GTR, a track-only customer version that diverges significantly from its racing sibling.

Two decades after the iconic F1 GTR last raced at Le Mans, McLaren is returning to endurance racing’s premier class with renewed ambition. The MCL-HY FIA Hypercar will compete for championship points, while the GTR is positioned as a bespoke, non-hybrid alternative for a select group of owners.

MCL-HY GTR: A More Powerful, Lighter Track Weapon

The MCL-HY GTR stands out for its performance advantages. Unlike the FIA-mandated hybrid system in the racing version, the GTR relies solely on a twin-turbocharged 2.9-liter V6 engine, producing 720 hp (537 kW / 730 PS). This output surpasses the electrified racer, which is limited to 697 hp (520 kW / 707 PS) to maintain parity in competition.

McLaren also expects the GTR to weigh less than the racer’s 1,030 kg (2,270 lbs), thanks to the absence of hybrid components. The company emphasizes the GTR’s focus on delivering an authentic Hypercar experience:

“This decision ensures that clients benefit from a purer driving experience on track days, one that delivers authentic Hypercar performance and feel without additional complexity, and a simpler ownership model that prioritises accessibility above all else.”

Shared Design, Distinct Personalities

Both the MCL-HY FIA Hypercar and GTR share a carbon fiber monocoque chassis and identical exterior styling, though their liveries differ. The racing prototype features an orange livery inspired by the classic McLaren M6A, driven by Bruce McLaren in the 1960s. The GTR, in contrast, adopts a silver and orange accented design, offering a more subdued yet distinctive appearance.

Key design elements include:

• Oversized carbon fiber aerodynamic features for high downforce;
• A long wheelbase for stability;
• A droplet-shaped cabin for driver ergonomics;
• Exposed slick tires through front fender cutouts;
• A large central fin for aerodynamic efficiency;
• Gill-style side vents for cooling;
• Slim LED taillights integrated into the rear wing endplates.

Exclusive Ownership: Project: Endurance Program

Access to the MCL-HY GTR is strictly controlled through McLaren’s Project: Endurance program. Owners receive a two-year immersive track program, featuring:

• Professional coaching;
• A dedicated pit crew;
• Race engineering support.

While McLaren has not disclosed pricing or production numbers, it confirms that supply will be tightly limited, with only a handful of clients invited to purchase the vehicle. First deliveries are slated for late 2027.

As for the MCL-HY FIA Hypercar, McLaren plans to begin testing later this month, ahead of its homologation and debut in the WEC.
