Ford to Develop 5.4-Liter V8 for 2027 Le Mans

Live Poll

Would you choose a naturally aspirated V8 over a supercharged one when buying your next car?

Ford is developing a naturally aspirated 5.4-liter V8 for its 2027 FIA World Endurance Championship and Le Mans program. The company has not confirmed a road-going version of the racing engine.

Why it matters

The engine reportedly reaches beyond 9,000 rpm, signaling Ford's focus on sustained high-speed performance under racing conditions. A road-going derivative could eventually appear in a future Mustang, though this remains unconfirmed.

The reported 5.4-liter engine targets roughly 670 hp under regulation limits and reaches beyond 9,000 rpm, compared with the 815 hp and 5.2-liter supercharged V8 in the Mustang GTD. Ford has not released final production-equivalent specifications.

The players

Ford

Ford Motor Company is a Dearborn, Michigan-based automaker that has competed in endurance racing and sells the Mustang sports car.

The details

Ford's engine is derived from the Coyote architecture and omits turbochargers and intercoolers to reduce mechanical complexity while retaining a recognizable American V8 exhaust note. Ford is testing the engine in a virtual program in Dearborn that recreates the Circuit de la Sarthe and incorporates data from human drivers, including mistakes and throttle blips.

Roadmap

Ford's 5.4-liter V8 continues the American naturally aspirated V8 lineage exemplified by the GM LS7 in the 2006-2013 Corvette Z06, which reached 7,000 rpm from 7.0 liters. Ford's engine pushes beyond that redline past 9,000 rpm while competing against European endurance rivals such as the Ferrari 458 Italia and Porsche 918 Spyder.

No road-going version has been confirmed, so buyers cannot yet expect a Mustang with this engine. Any production application would depend on a future Ford decision that has not been announced.

The takeaway

Ford's racing V8 shows how endurance programs can shape future performance engines, though a street version remains speculative until Ford confirms it. Watch for official announcements ahead of the 2027 season.
