The Hennessey Viper Venom 1000 Twin Turbo is an upgraded version of the Dodge Viper offered for sale as a whole car or as an upgrade by Hennessey Performance Engineering, also known as HPE. It comes in two variants, a coupe and a convertible. It has a theoretical maximum production run of 24 vehicles.[1] HPE claims the Venom 1000 Twin Turbo is "The fastest and most powerful limited-edition street car in the world." [1]

As tested in 2006 by Motor Trend magazine, the coupe variant weighed 3469 lb, cost $187,710, and had a 0.52 drag coefficient.[2]


The stock 2003 Viper V10 motor puts out 500 brake horsepower (370 kW) and 525 foot pounds (712 N·m). HPE increases the output to about 1,000 hp and 1100 ft·lbf (1,490 N·m)of torque with the following modifications:


  • VenomAero body modifications (front air dam, rear diffuser & spoiler)
  • Lowered suspension
  • 2-way adjustable coilover shock absorbers
  • Brembo upgraded braking system
  • Adjustable traction control system
  • Quaife differential
  • Hennessey Venom 7R forged aluminum wheels (19x10 front, 20x13 rear)
  • Michelin Pilot Sport 2 tyres: 275/30 YR19 front, 335/30 YR20 rear



According to testing by Motor Trend in 2005, the Venom failed California emissions testing due to excess carbon monoxide, but is legal in the other 49 states. However, the car was tuned for a standing mile race on a closed circuit, and Motor Trend surprised Hennessey with this emissions test, and the car only failed by a very small threshold, which could have easily been remedied with a less aggressive tune.[3]
