Hypercar builder John Hennessey joins Joe Rogan to talk extreme horsepower, his scrappy origin story, and a deep dive into MMA, comedy, and cold plunges.

John Hennessey — Founder and CEO of Hennessey Performance Engineering and Hennessey Special Vehicles, builder of extreme high-horsepower cars and trucks including the 1,817-horsepower Venom F5 hypercar.
John Hennessey explains how a tough, abusive childhood and a chip on his shoulder fueled a 40-year career building absurdly powerful vehicles, from modifying Dodge Vipers in the early 90s to the bespoke, carbon-fiber Venom F5. He traces his path from amateur Pikes Peak racing and an asbestos-cleanup business into a tuning empire that has modified roughly 15,000 vehicles. Joe shares his own origin story through Taekwondo, kickboxing, stand-up comedy, newspaper routes, pool halls, and how he fell into UFC interviews and then podcasting. The two riff on car culture, Top Gear's staged stunts and reckless antics, and Jay Leno's legendary garage. They close on health, with Hennessey describing quitting Ritalin after 25 years and replacing it with daily cold plunges, while Joe details his cold plunge, sauna, and fasting routines.
