Texas-based performance vehicle manufacturer Hennessey recently showcased the Venom 1200 Mustang GT500, touted as one of the group’s “most powerful muscle cars Hennessey Performance has ever produced.”

As the name suggests, the Venom 1200 GT500 produces a staggering 1,204 brake horsepower at 7,600 RPM and 902 lb-ft of torque at 5,200 RPM. Getting up to this level of performance requires E85 fuel and a myriad of Hennessey upgrades.

The Venom 1200 is, of course, built off of the most powerful factory-produced Mustang ever: Shelby’s GT500, powered by the supercharged “Predator” engine, a 5.2-liter V8 rated at 760 horsepower and 625 lb-ft of torque from the factory. Hennessey added a higher capacity 3.8-liter supercharger, a high-flow induction system, new fuel rails and injectors, and an air/oil separation system. Other swaps include better fittings, lines, belts and tensioners. The factory dual-clutch transmission has been recalibrated to handle this beefed-up muscle, revved up on the Hennessey dynamometer before hitting the streets.

Of course, flaunting the upgraded goods is a bespoke set of exterior modifications, from badging to graphics. Owners will be able to add a throwback livery to their Venom 1200 which harkens back to the Ford Mark II GT40 which raced in the 1966 24 Hours of Daytona. This red, white and black package costs an additional $4,950.

And that’s where total pricing comes in. The Venom 1200 upgrade costs $59,950, exclusively available for the base Ford Shelby GT500 Mustang which, in of itself, retails starting at $80,815 with delivery for the 2022 model year. Adding to exclusivity is availability, with the Venom being limited to just 66 units. Each unit will come with a serial-numbered plaque.
