It's one thing to build a supercar from the ground up. It's something else to take a sports car, break it apart, lengthen it, and put it back together with a different engine inside. Yet that's exactly the case with the Hennessey Venom GT ($TBA). Limited to just 10 per year, the ultra-exclusive Venom GT is based on the Lotus Elise, but is powered by the Corvette ZR1's supercharged 6.2 liter LS9 V8. Hennessey has tuned the stock engine's output up to 725hp, but will also offer twin-turbo versions putting out 1,000 and 1,200hp, respectively. Other Ferrari-fighting features include a six-speed Ricardo gearbox, 15-inch carbon ceramic brake rotors, a programmable traction control system, an active aerodynamics system with adjustable rear wing, and massive Michelin PS2 tires. The Bat signal awaits.
