Hennessey-Tuned Ford Mustang Dark Horse Debuts With 850 Horsepower

• Hennessey's take on the Ford Mustang Dark Horse makes 850 horsepower and 650 lb-ft of torque.
• A new supercharger and other engine tweaks add as much power as an Integra Type S makes.
• Hennessey has yet to announce pricing, but production starts later this year.

The brand’s own forged aluminum alloy wheels are also fitted, and new Brembo brakes should help the new power figures remain at least somewhat in check. Because supercharger whine isn’t enough of a complement to the new power figures, Hennessey also adds a carbon-fiber splitter, side skirts and rear spoiler. Other cosmetic changes include optional Heritage graphics and Hennessey embroidered headrests, and new badging and script can be found on the quarter panels and bumper.

Like many of the brand’s other tuned-up creations, the H850 is backed by a three-year/36,000-mile limited warranty. Production is set for fourth quarter of 2023, but pricing has not yet been announced.

Edmunds says

It's staggering how much power Hennessey is able to extract with relatively simple upgrades. A few changes to the fuel system and a supercharger aren't much to create a 350-horsepower gain. We're sure the H850 will be ludicrously expensive, but for a Mustang making more power than some McLarens, many will likely find the price worth the pain (to their wallets).
