2025 McLaren 750S

M840T

Twin-Turbo Flat-Plane V8

A flat-plane-crank V8 that spins to 8,500 rpm with a hard, metallic top-end shriek and explosive, lag-light boost, defining the savage character of the 750S and its track-bred siblings.

Designed by McLaren in partnership with Ricardo and hand-assembled at Ricardo's facility in Shoreham-by-Sea, England, its block architecture descends from a 1980s–90s Nissan VRH racing engine whose IP McLaren acquired via Tom Walkinshaw Racing.

• Its ancestral VRH35 design powered the Nissan R390 GT1 at the 24 Hours of Le Mans in 1997 and 1998.
• The 750S version shares only about 59 percent of its parts with the 720S engine it evolved from, with a lengthened stroke and lighter internals.
• The flat-plane crankshaft is what gives it the high-pitched, exotic wail rather than the lazy burble of a cross-plane American V8.
