Welcome to Hennessey Performance (HPE)

Hennessey Performance was founded more than 30 years ago and has been focused on pioneering automotive performance ever since. John Hennessey, our founder, and CEO made a name for himself in the early 1990s with race-winning vehicle modifications that gained global fame. Pursuing his true passion, John left his small environmental business and aimed his entrepreneurial skills at modifying, tuning, and enhancing high performance cars and trucks. Today, the company operates Hennessey Performance Engineering (HPE), Hennessey Special Vehicles (HSV), and the world-famous Tuner School where future vehicle engineers and tuners learn the trade. Hennessey has modified more than 10,000 cars and trucks since opening in 1991, and is home to the largest lineup of late-model high-performance sports cars, muscle cars, supercars, trucks & SUVs, including the Venom F5 hypercar. 

Who We Are

Hennessey Performance is a team of 70+ dedicated co-workers. Our team is responsible for design, engineering, manufacturing, assembly, testing, production, and quality control – our operation is comprehensive. We are friends, parents, co-workers, and students with varied backgrounds, interests, passions, and hobbies. Diversity is our strength, which we complement with hundreds of years of combined experience in our fields. Our team is unified and passionate – we strive to innovate and deliver the best product that we can.

What We Do

Hennessey Performance makes fast cars go faster. Our specialty is increasing the performance envelope of high-performance cars and trucks through engine, suspension, and chassis upgrades – we enhance both domestic and import vehicles to supercar levels. Our Texas facility boasts a massive workshop with more than 30 service bays, 24 hydraulic lifts, two in-ground dynamometers, laser alignment racks, and the latest tools and technology. We have a dedicated R&D facility and a state-of-the-art design studio on our campus, which allows our team of expert engineers and technicians to do both design and testing on-site. One of our greatest assets is our private proving grounds and 1/4-mile dragstrip – the Pennzoil Proving Ground at Lonestar Motorsports Park – so Hennessey teams may test, evaluate, and refine the vehicle enhancements without leaving our property.

Where We Are

Hennessey Performance proudly calls Texas home. The second-largest state in the United States is known for legendary hardy people who are friendly and full of pride. Going big – especially when it comes to performance and horsepower – is the Texas way! On a map, Hennessey Performance is located at Lonestar Motorsports Park outside of Sealy, Texas, which is about 45 minutes west of Houston. You can’t miss our fully equipped 142-acre property along the south side of Texas Interstate 10. We’ve got a massive 51,000 square foot workshop – home to Hennessey Performance Engineering (HPE), Hennessey Special Vehicles (HSV), and our world-famous Tuner School – a road course, and 1/4 mile dragstrip.
