As tested in 2006 by Motor Trend magazine, the coupe variant weighed 3,469 lb (1,574 kg), cost $187,710, and had a drag coefficient of 0.52.[2]
The Venom 1000TT is powered by an 8.5 liter V10 motor from a 2003 Viper that originally produced 368 kW (493 hp) and 525 lb⋅ft (712 N⋅m) of torque, but has been modified to produce 1,000 bhp (746 kW; 1,014 PS) and 1,100 lb⋅ft (1,491 N⋅m) of torque. The engine has been stroked from 8.3 to 8.55 liters, and has had the compression ratio lowered to 9.0:1. It also has been equipped with Twin Garrett ball bearing turbochargers and a front-mounted air-to-air intercooler.
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, 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][additional citation(s) needed]
