Hennessey H850 Mustang: the Dark Horse gets supercharged

Published: 20 July 2023 Updated: 20 July 2023

► Dark Horse gets the Hennessey treatment
► Supercharger and carbonfibre bodywork additions
► 70% more power than the standard car

The Ford Mustang Dark Horse is one of the most powerful Pony cars to ever roll out of the Blue Oval – but what if you want even more power? Enter Hennessey’s H850 Mustang Dark Horse, a supercharged take on Ford’s flagship ‘Stang. 

‘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,’ said John Hennessey, company founder, and CEO. ‘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.’

Did someone say supercharged? 

Hennessey’s package consists of a two parts; a major engine upgrade and a range of cosmetic exterior upgrades. 

Engineers from the Texas-based hypercar maker have kept the Dark Horse’s 4th Generation 5.0-ltire Coyote V8 intact – complete with the GT500’s connecting rods and a dual throttle body fitted at the Ford factory. However, Hennessey has added a high-performance supercharger and a high-flow air induction system, upgraded fuel injectors and a new fuel pump.

When combined with new engine management software, the H850 Dark Horse puts out around 850bhp and 650lb ft of torque – that’s a 70% bump in power compared to the stock figures. 

The other half of the equation is more cosmetic; Hennessey has fitted its H850 with a new range of carbonfibre appendages. A lightweight front splitter, side skirts and rear spoiler have been added on the outside, and the new upgraded ‘Stang will also roll on forged aluminium alloy wheels. 

Aside from the new supercharger noises and bodywork upgrades, you’ll be able to pick out the H850 from its embroidered head restraints and Hennessy badging. Production will begin in Q4 of 2023, though there’s no word if it’ll reach the UK yet.

We’ll update this article when we know more.
