Hennessey Performance is celebrating its 35th anniversary of making fast cars go faster with a limited run of its supercharged Super Venom Mustang. For the Super Venom, Hennessey takes the Ford Mustang's factory 5.0‑liter V8 and does what Hennessey does best: adds more power.Being an anniversary model, there's obviously a bit more style, too. You'll find aero upgrades, visual changes, and plenty of branding to make sure people know this ain't some Dark Horse or Shelby. Take a good look, though, because these photos could be the only time you see one. Only 35– one for each year Hennessey has been in business –will be built. More Power, More Aero, More Hennessey HennesseyHennessey starts with a healthy infusion of power, 850 horsepower to be specific. That's a big jump from 500 in a normal Dark Horse, and it's probably more than the Dark Horse SC, too. We say probably because Ford hasn't yet made an official announcement on its new supercharged Mustang, but it almost certainly won't exceed the 815 ponies found in the GTD.Hennessey's 'Stang also conveniently out-powers the 2026 Shelby Super Snake's claimed 830 hp, which we suspect is no accident. Torque goes up to 650 pound-feet, so this modified Mustang should have no problem killing its tires.A tuner can't just make a car go faster and call it a day anymore. Carbon fiber is vital, so the Super Venom Mustang gets a carbon fiber performance kit called VenomAero to aid cooling and handling. Hennessey doesn't detail the changes, but we can easily see fender vents, a front lip, side sills, and a big wing on the back.The anniversary graphics are pretty self-explanatory. You'll find 35 fender badges and a stylized 91 hood graphic to reference Hennessey’s founding year, 1991. Super Venom script on the side and Hennessey branding all around complete the package.“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. We’ve scaled the business while staying true to our roots, and looking ahead, there’s a tremendous amount to be excited about."– John Hennessey, founder and CEO Chasing Power And Speed HennesseyIndeed, Hennessey Performance has grown dramatically over 35 years, and follows a vaguely similar trajectory to Shelby American. Like Carroll Shelby, John Hennessey is from Texas. One of his key early cars, the Hennessey Venom GT, was based on a British car. And while most famous for tuning Fords, again, like Shelby, Hennessey works with other manufacturers' cars in the pursuit of building four-wheeled missiles. Both icons have also aimed to build a car from scratch, although the Shelby Series 1 has been largely forgotten by car culture. Hennessey's first run at a full production car rather than tuning an existing factory car was the Hennessey Venom F5, developed with Delta Motorsport in the UK. It's assembled in the US with Hennessey's Fury engine – a twin-turbo 6.6-liter V8 capable of 1,817 hp. Production is limited to 24 units, and clearly built with the production car speed record in mind. In 2024, John Hennessy broke the half-mile standing start record with the Venom F5 by hitting 219 mph while covering the distance in 14.44 seconds.At this point, Hennessey says it has "re‑engineered" more than 18,000 vehicles for customers around the globe, and the company's Tuner School has trained hundreds of technicians, with many becoming part of Hennessey's 140-strong team. Hennessey also plans to build out its Texas facility to over 100,000 square feet, bring composite manufacturing and vehicle painting in-house, and scale its vehicle production with the aim of 2,000 units per year.Source: Hennessey Performance
