1999 Hennessey Venom 650R exterior and interior photos.
As is his custom, John Hennessey takes an already fast car—the Dodge Viper—and makes it faster. How's 207 mph sound?
This 1999 Hennessey Venom 650R wears a paint color dubbed "Prowler Yellow."
The Hennessey Venom 650R's aero add-ons cost $20,000 when rendered in carbon fiber, as they are here.
In the name of track performance, the Hennessey Venom 650R loses its catalytic converters. And air-conditioning system.
The Venom 650R's upgraded brakes stopped it from 70 mph in 143 feet—and that's without ABS.
The Venom 650R looks as subtle as its $173,031 price.
The Venom 650R interior is mostly stock but for nonfunctional AC.
The new lower clip includes brake-cooling ducts.
If the stock Viper's 450 horsepower isn't enough, the 650R's 670 naturally aspirated horses should raise your pulse a bit.
The Venom's V-10 displaces 8.4 liters.
The front brake rotors are 13 inches in diameter, with four-piston calipers.
Hennessey removed the rear wing for his 207-mph run, but we figure the Venom will probably still crack 200 mph with it in place.
The Venom's aero package adds 100 pounds of downforce at the rear end.
Somewhat quieter HMS mufflers are available—and probably sensible.
