Hennessey announces 850-hp 2024 Ford Mustang Dark Horse

The seventh-generation Ford Mustang hasn't reached showrooms yet, and it's allegedly "much more difficult to tune" than its predecessor, but that won't stop Hennessey from supercharging it. The brand announced a package called H850 that increases horsepower to 850.

Based on the range-topping Dark Horse trim, the bundle includes a supercharger for the 5.0-liter Coyote V8, a high-flow intake system, upgraded fuel injectors and a new fuel pump. Hennessey also adds engine management software it developed in-house. The end result will be 850 horsepower and 650 pound-feet of torque, numbers that represent massive increases over the stock, naturally-aspirated V8's figures of 500 and 418, respectively. Buyers can keep the standard six-speed manual transmission or pay extra for a 10-speed automatic.

Hennessey hasn't released any other performance numbers. And, while it doesn't sound like the company is making modifications to the engine's internal oily bits, the Dark Horse already has engine upgrades from Ford such as forged connecting rods and strengthened camshafts.
