The McLaren P76 is a 3,799 cc, 90‑degree V8 twin‑turbocharged petrol engine produced between 2011 and 2017. Developed in partnership with Ricardo, it features dual overhead camshafts (DOHC), dry sump lubrication, and direct fuel injection. This engine powered McLaren's inaugural road car, delivering outputs from 592 PS to 650 PS, establishing a benchmark for high‑performance, everyday supercars.

All production years (2011–2017) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/MCL/MP412C).
The McLaren P76 is a 3,799 cc 90-degree V8 twin-turbocharged petrol engine engineered for high-performance supercars (2011-2017). It combines a flat-plane crankshaft with twin-turbochargers mounted in the ‘hot vee’ to deliver instant throttle response and immense power. Designed to meet Euro 5 standards, it balances track-focused performance with road usability.

The McLaren P76 was used exclusively in McLaren Automotive's first generation of road cars with mid-engine, longitudinal mounting. This engine powered the foundational MP4-12C platform, with minor ECU and boost revisions for the 650S and 625C variants, maintaining full mechanical interchangeability. All adaptations are documented in OEM technical bulletins.
The P76's primary reliability focus is managing heat in the ‘hot vee’ configuration, with elevated thermal stress noted in track use. McLaren service data indicates the water pump and related coolant hoses are common service items, while UK DVSA records show no systemic emissions failures. Sustained high-RPM operation and track use make cooling system integrity and oil quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The P76 is a robust engine designed for high performance. Its main service items are the water pump and ignition coils. With proper maintenance, including regular fluid changes and addressing the known wastegate rattle, it can be very reliable. Its use of a chain-driven valvetrain eliminates a major wear item found in many contemporaries.
The most frequently documented issues are water pump failure, turbo wastegate rattle, ignition coil pack degradation, and leaks from the oil cooler lines. These are well-covered in McLaren service bulletins and are generally straightforward repairs for a qualified technician.
The P76 engine was used in the first generation of modern McLarens: the MP4-12C (2011-2014), the 650S (2014-2017), and the region-specific 625C (2014-2015). It powered both Coupe and Spider variants of these models.
Yes, the P76 responds very well to ECU remapping. Stage 1 tunes can reliably add 50-80 PS. More aggressive modifications, like upgraded turbos and intercoolers, can yield significantly higher outputs. The engine's internals, including the flat-plane crank, are very strong and can handle increased torque.
As expected for a 600+ PS supercar, fuel economy is not its forte. Real-world figures are typically 15-18 mpg (UK) in mixed driving, dropping to single digits under hard acceleration. The official combined figure for the MP4-12C was around 24 mpg (UK), but this is rarely achievable in normal use.
Yes. Like virtually all modern high-performance engines, the P76 is an interference design. A failure of the timing chain (though extremely rare) would likely result in catastrophic valve and piston damage. Fortunately, the chain is designed for the engine's lifetime.
McLaren specifies a high-quality 5W-40 fully synthetic oil meeting their specific Supercar standard. Using the correct oil is vital for protecting the engine, particularly the turbos and the flat-plane crankshaft under high-stress conditions.
