Sealy, Texas (May 21, 2024) – Hennessey, the renowned Texas-based hypercar manufacturer and high-performance vehicle specialist, has unveiled the stunning performance data for its supercharged ‘H850’ Mustang Dark Horse, now rolling off the production line at its Sealy headquarters. With an astonishing 70 percent power boost, the H850 Mustang Dark Horse churns out a jaw-dropping 850 horsepower and 650 lb-ft of torque.
The 2024 Ford Mustang Dark Horse, a high-performance iteration of the celebrated ‘S650’ Mustang, starts with a naturally aspirated Gen-4 Coyote 5.0-liter V8 engine. Hennessey’s expert engineers enhance this powerhouse with a high-performance supercharger, a high-flow air induction system, upgraded fuel injectors, an improved fuel pump, and Hennessey’s meticulously crafted engine management system.
In its stock form, Ford’s Dark Horse boasts 500 bhp and accelerates from 0-60 mph in 3.7 seconds with the 10-speed automatic transmission. Hennessey’s supercharged H850 variant shatters this record, achieving 0-60 mph in just 3.2 seconds. The standard Dark Horse completes the quarter-mile in 12 seconds at 118.4 mph, while the H850 conquers the same distance in a mere 10.9 seconds at an impressive 133 mph.
John Hennessey, Founder and CEO of Hennessey Performance, remarked, “Our supercharged H850 Mustang Dark Horse builds upon Ford’s legacy of delivering passion-driven vehicles like the V8-powered S650 Mustang. We are thrilled to amplify this iconic muscle car with Hennessey’s signature performance, delivering a driving experience that ignites the senses.”
Hennessey’s modifications elevate the Mustang’s performance to rival even the upcoming $300,000 Ford Mustang GTD, which features 800 horsepower. With the H850’s supercharged V8, enthusiasts receive exceptional value, supercar-like performance, and the exhilarating soundtrack of a powerful engine.
Owners of the Hennessey ‘H850’ Mustang can further customize their Dark Horse with optional Hennessey Heritage Graphics and forged performance wheels in a sleek gloss anthracite finish. Distinctive touches include Hennessey and H850 badging, embroidered headrests, and a serial-numbered engine plaque.
The ‘H850’ Mustang Dark Horse is available in both automatic and 6-speed manual versions, each supported by Hennessey’s comprehensive 3-year/36,000-mile limited warranty. Production is already underway at Hennessey’s Sealy, Texas facility.
