Hennessey, the Texas-based hypercar manufacturer and high-performance vehicle creator, has revealed performance data for its supercharged ‘H850’ Mustang Dark Horse, which is now in production at its Sealy HQ. Hennessey’s engineers have transformed the performance of America’s iconic pony car with a 70 per cent power upgrade, achieving 850 horsepower, alongside boosted torque of 650 lb-ft.

The 2024 Ford Mustang Dark Horse is the performance version of the acclaimed ‘S650’ Mustang. The stock Dark Horse has a naturally aspirated Gen-4 Coyote 5.0-litre V8, to which Hennessey adds a high-performance supercharger, high-flow air induction system, upgraded fuel injectors and fuel pump, plus Hennessey’s rigorously developed engine management system.

From the factory, Ford’s Dark Horse has 500 bhp and can hit 60 mph from stationary in 3.7 seconds, in 10-speed auto form. Hennessey’s uprated H850 Mustang hits the same speed in just 3.2 seconds. The standard Dark Horse completes the ¼ mile in 12 seconds at 118.4 mph. Hennessey betters this benchmark too, with the H850 auto achieving the same distance in 10.9 seconds at 133 mph.


John Hennessey, company Founder, and CEO“Our supercharged H850 Mustang Dark Horse builds on Ford’s commitment to provide automotive enthusiasts with passion products like the snarling V8-powered S650 Mustang. We’re excited to unleash Hennessey’s passion for performance on America’s most iconic muscle car with all the sights, sounds, smells, and sensations that get our blood pumping!”

To complement its potent powerplant, Hennessey ‘H850’ Mustang owners can visually enhance their Dark Horse with optional Hennessey Heritage Graphics and forged performance wheels in gloss anthracite. Setting the Hennessey apart further, each model features Hennessey and H850 badging, Hennessey embroidered headrests, and a serial-numbered engine plaque.
