Well-known performance company Hennessey started modifying Dodge Vipers in 1993, but it wasn’t until 2006 that they introduced the outrageous Venom 1000 Twin Turbo. This outlandish interpretation of the Viper offered otherworldly performance. The Venom could sprint from 0–60 in a mere 2.5 seconds and top out at an insane 255 mph. The V-10 engine was completely modified with the addition of two massive turbochargers, and the suspension and brakes were upgraded to match the tremendous power output.

The front and rear bodywork of the Venom 1000 was modified for improved aerodynamics, and the aggressive extended nose gave the Hennessey a distinctive look. Originally priced at $225,000, the Venom 1000 was a massive leap above the $87,000 base price of the standard Viper. When Motor Trend tested the Venom when new, the performance figures were simply astonishing. Most notable, the Venom bested the Veyron to 200 mph by four seconds.

This Venom 1000 Twin Turbo was reportedly first owned by NFL football player Mario Williams. It is the 20th of only 24 examples produced, of which only six were convertibles. The Viper has since been in the current owner’s collection for the last five years. Finished in menacing Viper Crystal Pearl Grey, it stands out from the run-of-the-mill Vipers, and its performance remains comparable to today’s ultra-horsepower hypercars. It has been driven less than 7,700 miles since new and has never been tracked by its owner, a prominent collector based in Georgia.

With unbelievable performance and a six-speed manual transmission, the Venom 1000 Twin Turbo is a true enthusiast’s supercar. Even after 14 years, it will continue to keep up with anything on the road. This exceptional Hennessey Venom is in pristine condition and is a beautiful example of what has become a highly collectable Viper in a class of its own.
