Hennessey reveals supercharged, 850-hp 2024 Mustang Dark Horse

Hennessey Performance has unveiled its flagship version of the new, seventh-generation Mustang Dark Horse. Before we delve into Hennessey’s black magic, a few facts on where the Dark Horse starts: From the factory, the Dark Horse already comes with Brembo brakes and 5.0-liter Coyote V-8 upgraded with connecting rods from the GT500 and a new twin throttle-body intake manifold. The tweaks are enough to make the Dark Horse’s engine the most powerful version of the 5.0-liter Coyote to date, at 500 hp.

To make the Dark Horse even more special, Hennessey adds a new air intake system that feeds a positive displacement supercharger, along with a new fuel pump and injectors to keep up with demand. After Hennessey’s tuneup, the result is 850 hp and 650 lb-ft of torque, more than enough to transform the Dark Horse into a whole new breed of pony, matching the power level of the supercharged 5.2-liter, flat-plane-crank V-8 found in Hennessey’s sixth-generation GT350.

In addition to the massive power upgrade, every H850 Dark Horse will wear a front splitter, side skirts, and a rear spoiler, each formed from carbon fiber. Unique forged aluminum wheels and Hennessey badging on the quarter panels and rear fascia will also set every H850 apart. Inside, the modifications are minimal, with Hennessey embroidered headrests. The “heritage” graphics seen on this red example, which resemble the door stripes from the 1969 Boss 302, are optional.

John Hennessey, company founder, and CEO, is excited to bring the next chapter of Hennessey performance to market. “Our supercharged Mustang builds have continually been customer favorites over the years, and Ford’s improved S650 platform will prove to be its most capable. Without question, our supercharged 850 horsepower Dark Horse model will be one of the most exciting and powerful muscle cars on the road—sure to turn heads with its distinctive supercharger wail and exhaust note.”

Each H850 package is backed by Hennessey’s three-year, 36,000-mile warranty and Hennessey is currently taking orders, although for now, there’s no official word pricing. Expect the first models to hit the street at the end of this year.
