A rare 2021 Ford Mustang GT, enhanced by Hennessey Performance to produce 808 horsepower, is now available for bidding
A one-of-a-kind 2021 Ford Mustang GT, modified by Hennessey Performance to 808 horsepower, is set to cross the auction block. As Serial Number 001 of Hennessey’s high-performance Mustang lineup, this limited-production muscle car is expected to draw strong interest from collectors and enthusiasts.

Hennessey, renowned for pushing the limits of American performance vehicles, equipped this Mustang GT with a 3.0-liter supercharger system, complemented by an air-to-water intercooler, upgraded fuel injectors, and a high-flow induction system. With 677 lb-ft of torque at 4,500 rpm, this Mustang delivers exhilarating acceleration, refined further by chassis dyno calibration for optimal power delivery.
Beyond raw performance, aerodynamics and handling have been significantly upgraded. The CarbonAero package includes a front carbon fiber splitter, carbon fiber side sills, and a rear spoiler with a Gurney lip. The lowered suspension system and Michelin Pilot Sport Cup2 tires on 20-inch alloy wheels ensure exceptional grip, while Brembo brakes—six-piston front, four-piston rear—paired with 15.1-inch rotors provide superior stopping power.
The interior reflects Hennessey’s signature touches, featuring embroidered headrests, a serial-numbered dash plaque, and a heritage graphics package that underscores this Mustang’s exclusivity.

With only 200 test miles on the odometer and a full Ford parts warranty valid through June 2025, this high-performance Mustang remains in near-new condition. Additionally, the drivetrain is covered under warranty for two more years or up to 60,000 miles.
Given its rare status as Serial #001, this Hennessey Mustang GT represents an opportunity to own a piece of high-performance history. Bidding is expected to be competitive as muscle car enthusiasts vie for a machine that blends iconic American power with cutting-edge tuning and engineering.
