Hennessey Special Vehicles[edit]

Hennessey owns the recently-established Hennessey Special Vehicles division, in which it builds the Hennessey Venom GT sports car line-up. The division is tasked to learn from its experiences with the Venom GT and apply it to the newest variation, the Hennessey Venom F5, which will succeed the Venom GT.[2] All vehicles sold under the division are branded as a regular Hennessey model, despite being built by the division.

The Venom F5 is the first vehicle to be produced by the recently-established division. The car will be the successor to the Venom GT and continue the legacy as World's Fastest Production Car.


Hennessey has been the subject of numerous lawsuits and Better Business Bureau complaints throughout the years, with many BBB complaints left unresolved[3] and, according to court records, many judgements entered against Hennessey. According to Car and Driver, a 2002 Dun & Bradstreet search had also turned up significant concern about Hennessey's financial footing. As of June 1, 2016 Hennessey Performance Engineering holds an "F" Rating from the BBB.[4] On April 31, 2016 Jalopnik published an article outlining Hennessey's many customer service and potential fraud issues.
