Based on the McLaren 650S Road Car The McLaren 650S GT3, introduced in 2014, is a race-ready version of the 650S, developed for GT3 competition worldwide.
Complies with FIA GT3 Regulations The 650S GT3 was built to meet FIA GT3 class regulations, making it eligible for series like the Blancpain GT Series, IMSA WeatherTech SportsCar Championship, and British GT Championship.
Detuned but Race-Optimized Twin-Turbo V8 The 3.8L twin-turbocharged V8 engine produces around 500-550 hp, lower than the road-going 650S’s 650 hp, but is optimized for endurance racing reliability.
Lightweight Carbon Fiber Monocoque Chassis The MonoCell carbon-fiber chassis, carried over from the road car, makes the 650S GT3 one of the lightest GT3 cars, improving handling and crash safety.
Aggressive Aerodynamic Package The 650S GT3 features a large fixed rear wing, wider front splitter, and aerodynamic side skirts, increasing downforce and high-speed stability.
Sequential Racing Gearbox for Faster Shifts Instead of the road-going 7-speed dual-clutch transmission, the 650S GT3 uses a 6-speed sequential gearbox, allowing for rapid shifts in race conditions.
Upgraded Suspension for Track Performance The GT3 version features a race-tuned suspension, with adjustable dampers, anti-roll bars, and lightweight racing components for better grip.
Significantly Lighter Than the Road Version Due to the removal of luxury features, use of lightweight racing materials, and a stripped-down interior, the 650S GT3 weighs significantly less than the standard 650S.
Replaced the McLaren MP4-12C GT3 The 650S GT3 replaced the MP4-12C GT3, bringing improved aerodynamics, increased durability, and better cooling, making it more competitive in endurance racing.
Succeeded by the McLaren 720S GT3 In 2018, McLaren introduced the 720S GT3, replacing the 650S GT3 with a more advanced chassis, better aerodynamics, and improved durability for endurance racing.

The 650S GT3 is McLaren’s track-only weapon. A 3.8L twin-turbo V8 monster built for FIA GT3 racing. With only ~50 units produced, it’s rarer than a P1 and trades like a blue-chip motorsport asset.
