Hennessey Reveals Performance Data for 850 Horsepower 2024 Mustang Dark Horse

  • Production now under way of Hennessey supercharged ‘H850’ Mustang Dark Horse
  • New Mustang from Hennessey achieves 0-60 mph in 3.2 seconds and ¼ mile in 10.9 seconds
  • ‘H850’ Mustang Dark Horse boasts 850 horsepower and 650 lb-ft of torque
  • Upgrade packages backed by Hennessey’s comprehensive 3-year / 36,000-mile limited warranty

Sealy, Texas (May 21, 2024) 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 percent 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-liter 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!”

Hennessey’s enhancement to the stock Ford Mustang even eclipses the forthcoming $300,000 Ford Mustang GTD – the street-legal race car that boasts 800 horsepower. In comparison, Hennessey’s upgrade to the Dark Horse delivers serious bang for buck alongside supercar-like performance and the glory of a supercharged V8 soundtrack.

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 head rests, and a serial-numbered engine plaque.

The ‘H850’ Mustang Dark Horse is available in both automatic or 6-speed manual form with both variants backed by Hennessey’s comprehensive 3-year / 36,000-mile limited warranty. Production of the new models is already under way at Hennessey’s Sealy, Texas HQ. Interested parties can find out more and place orders for global shipping through authorized Ford retailers, or with Hennessey directly at HennesseyPerformance.com, or by calling +1 979.885.1300.
