When Hennessey launched the Super Venom Mustang in early 2025, 91 examples were built as a nod to its founding year. For the firm’s 35th anniversary, the Texas tuner is revisiting the formula with a run of just 35 cars, celebrating three and a half decades in the business of “making fast cars faster”.

The mechanical headline remains unchanged from the original: Hennessey takes Ford’s 5.0-litre Coyote V8 from 500bhp to 850bhp through a larger Whipple supercharger, high-flow induction, uprated injectors, and revised mapping. Torque rises to 650lb-ft at 4,900rpm, a 55 per cent increase over the Dark Horse. In Europe, where the Dark Horse is hampered by OPF filters to 447bhp, the horsepower jump is closer to 90 per cent. Fitted with the 10-speed automatic, 0–60mph takes 3.2 seconds, while the muscle-car benchmark quarter-mile is covered in 10.9 seconds at 133mph. A six-speed manual is also available.

What distinguishes the anniversary cars is largely cosmetic. Unique 20-inch forged Vossen alloys wrapped in Pirelli P-Zero rubber feature alongside custom ‘35’ badges and a stylised ‘91’ bonnet graphic in lieu of a racing stripe. Otherwise, the VenomAero carbon-fibre package of splitter, bonnet vent, side skirts, and fixed rear wing carries over unchanged.

Hennessey leaves Ford’s standard Dark Horse suspension and braking setup untouched, preserving factory backing, its 3-year/36,000-mile warranty, and the car’s place in the Ford dealer network. Pricing is yet to be confirmed for the 35th Anniversary Super Venom, though the original 91-car run started at $163,950 in February 2025.

Hennessey has converted more than 18,000 vehicles in 35 years, and its work with Ford, GM, and Stellantis continues to grow. John Hennessey, founder and CEO said: “What started as a love for racing and going fast has turned into something far bigger than I ever imagined, but the fun of building extreme vehicles is still what drives us every day.”

The changes for the anniversary model might not be wholesale, but there are worse ways to mark a milestone than using it as an excuse to build another 850bhp Mustang.
