McLaren is poised to take a decisive step towards its return to top-level endurance racing, with its newly named LMDh prototype scheduled for its first on-track shakedown in early May. The British marque is preparing its entry into the FIA World Endurance Championship Hypercar class for the 2027 season, marking a significant expansion of its motorsport portfolio.
The initial running is expected to take place at Autodromo di Varano de’ Melegari, a circuit closely associated with chassis supplier Dallara. This venue has become a preferred location for discreet prototype rollouts, having previously hosted early testing of rival LMDh machinery under similarly controlled conditions.
In a recent announcement, McLaren confirmed that the car will carry the designation MCL-HY, aligning with the naming convention used by its Formula 1 programme. The “HY” suffix denotes its participation in the Hypercar category, signalling the company’s long-term ambitions in endurance racing.
McLaren MCL-HY: Key Technical Overview
| Component | Specification |
|---|---|
| Chassis | Dallara LMDh platform |
| Engine | 3.0-litre twin-turbo V6 |
| Engine Partner | Autotecnica Motori |
| Hybrid System | Standard Bosch LMDh unit |
| Target Debut | 2027 WEC season |
| Race Team | United Autosports |
At the heart of the MCL-HY lies a bespoke 3.0-litre twin-turbocharged V6 engine, derived from the road-going Artura programme but heavily adapted for endurance racing. The power unit is being developed in collaboration with Autotecnica Motori, a specialist engineering firm with extensive experience in high-performance racing engines. As required by LMDh regulations, the internal combustion engine will be paired with a standardised hybrid system supplied by Bosch.
The project has already progressed through key development milestones. Earlier this year, McLaren released footage of the engine’s first successful ignition on a test bench, followed by the formal confirmation of its technical partnerships. The upcoming shakedown will represent the first time the complete car operates as an integrated system on track.
Operational responsibility for the programme will rest with United Autosports, co-owned by McLaren Racing CEO Zak Brown and Richard Dean. The team brings considerable endurance racing expertise, including success in LMP2 competition. Strategic oversight will be provided by James Barclay, further strengthening the leadership structure.
Driver line-up announcements are beginning to take shape, with Mikkel Jensen confirmed as the first recruit. Additional names are expected in due course, with speculation linking experienced prototype racers such as Alex Lynn to the programme.
Development Timeline
| Phase | Milestone |
|---|---|
| Early 2026 | Engine bench testing completed |
| May 2026 | First on-track shakedown |
| Late 2026 | Expanded testing programme |
| 2027 | Competitive debut in WEC |
The forthcoming shakedown will be conducted under tightly controlled conditions, focusing on system checks, reliability validation, and baseline setup work rather than outright performance. From there, McLaren is expected to embark on an extensive testing schedule across multiple circuits in preparation for its competitive debut.
With major manufacturers increasingly committing to the Hypercar category, McLaren’s return adds further prestige and competition to the championship. While immediate success is never guaranteed in such a complex class, the MCL-HY represents a carefully structured effort that blends technical partnerships, experienced personnel, and long-term planning.
As the first laps approach, anticipation is building around whether McLaren can translate its storied racing heritage into a new era of endurance success.
