Hennessey's Timeline - An overview of how we got here

JOHN HENNESSEY TIMELINE OVERVIEW

1991

John Hennessey, a Texan with a craving for horsepower and speed, modifies and improves the performance of his brand-new Mitsubishi 3000GT VR-4, intending to compete in the Nevada Open Road Challenge, Pikes Peak Hill Climb, and Bonneville Salt Flats. As a result, his street-legal car, bumped from a stock 300 horsepower to 450 horsepower, successfully earns awards in all three events.

Inspired by his achievements and with encouragement and support from his new wife, Hope, John closed his private environmental business and opened Hennessey Motorsports.

1992

Working out of a rented garage, Hennessey Motorsports specializes in modifying turbocharged imports such as the Mitsubishi 3000 GT, Dodge Stealth, Toyota Supra, and Mazda RX-7.

In a two-page spread, Enthusiast magazine Car and Driver recounts John’s racing exploits and the modifications he made to his Mitsubishi 3000 GT (dubbed the “VR-200”).

1993

The first Viper “Venom 500” is built for a customer interested in competing in the Nevada Open Road Challenge. The car wins its class and finishes fourth overall with an average of 164 mph. It is newsworthy as the first Viper entered in any competitive event – earning it coverage in Car and Driver, Motor Trend, Hot Rod, and Car Craft magazines.

1994

The Viper “Venom 550” debuts with a 50 horsepower increase over the Venom 500 – credit Hennessey Motorsport’s design of the world’s first Viper 5-to-1 tubular headers and development of high-performance valve train improvements in conjunction with Competition Cams. Motor Trend track tests a Venom 500 and Venom 550 with both cars entering the magazine’s rather exclusive for the time “3-second club” by posting 0 to 60 mph runs of 3.7 and 3.5 seconds, respectively.

Hennessey Motorsport is involved in developing and selling the first hardtop designed for the Viper. A Belgian team campaigns two Vipers at the famed 24 Hours of Le Mans race utilizing exhaust headers, valve train components, and other racing parts from Hennessey – one of the team’s Vipers finishes an impressive tenth overall.

1995

John Hennessey becomes one of the founding members of the Viper Club of America. The new “Venom 600,” featuring a stroker kit with custom crank, debuts at Motor Trend shootout held at Firebird Raceway. It decisively beats the competition to earn the coveted “cover shot.”

An earlier experience at a Road & Track speed event did not result in a victory, but it brought home the lesson of having world-class test equipment. Hennessey Motorsport purchases one of the first Dyno Jet rolling chassis dynamometers.

The company has five full-time employees.

1996

The Dodge Viper GTS debuts and Hennessey offers an improved stroker kit to produce 650 horsepower resulting in the “Viper 650R” model.

1997

John Hennessey pilots a Viper 650R around the tricky high-speed oval at the Honda Proving Grounds in Arizona to become the first Viper to exceed 200 mph with a top speed of 203 mph. Motor Trend features the record run with a cover story.

1998

John drives his personal Viper GTS to establish a new speed record for the Elko Twin 50 open road race with an average of 177 mph on the return run.

The arrival of John and Hope Hennessey’s fifth child inspires John to put his family first. As a result, he retires from high-speed racing events – he will limit himself to road coarse and dragstrip testing in the future.

1999

The “Venom 800” makes its debut (the vehicle results from John Hennessey’s decision to develop a twin-turbo Viper V10). With 700 horsepower to the rear wheels, John sets a goal of 200 mph in the standing mile. On the strip, the Venom 800 comes up slightly shy with a speed of 197 mph but does become the first tuner car tested by Motor Trend to do 0 to 60 in 2.9 seconds and the 1/4 mile in 9.9 seconds.

2000-2003

Development continues on the Viper. The 1,000 horsepower “Venom 1000” debuts, and a Hennessey Venom 650R does 0 to 60 mph in 2.9 seconds an a 10.7 1/4-mile on street tires.

Hennessey Motorsports is renamed Hennessey Performance Engineering (HPE). The company has grown to a dozen full-time employees.

2004

Hennessey Performance Engineering completes the acquisition of the Lonestar Motorsports complex, including a 1/8-mile drag strip.

2005

In a Road & Track standing mile test on the runway at Lemoore Naval Air Station, the Hennessey Venom 1000 SRT-10 convertible posts the fastest top speed of 210.2 mph. The diverse field of 15 entrants includes a Saleen S7 and three race cars. The Venom 1000 is 7 mph faster than the Lola-Ford Cosworth Indy Car of Paul Gentilozzi

2006

John Hennessey refocuses his attention on building a comfortable, user-friendly, 200 mph road car. He commissions a designer in the UK to create plans for a vehicle based on a Lotus Elise with a Viper V10 amidships that is the precursor to the Venom GT.

2009
