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 ($TBA). Limited to just 10 per year, the ultra-exclusive Venom GT is based on the Lotus Elise, but is powered by the Corvette ZR1's supercharged 6.2 liter LS9 V8. Hennessey has tuned the stock engine's output up to 725hp, but will also offer twin-turbo versions putting out 1,000 and 1,200hp, respectively. Other Ferrari-fighting features include a six-speed Ricardo gearbox, 15-inch carbon ceramic brake rotors, a programmable traction control system, an active aerodynamics system with adjustable rear wing, and massive Michelin PS2 tires. The Bat signal awaits.
Four-door Veyron, anyone? While it's still just a concept — production models aren't expected to arrive until 2012 — the Bugatti 16C Galibier ($TBA) is very much a sedan successor to the blindingly fast supercar. Its engine will boast the same 8.0-liter W-16 architecture as the Veyron, but will employ two superchargers in place of the two-door's quad-turbos; other features will include dramatic LED-laden headlights and taillights, a unique dual-opening hood, a main "spine" running the length of both the exterior and interior, an eight-speed automatic transmission, eight individual tailpipes, and a luxurious, yacht-worthy interior. As for the price, you'd better start planning your bank robberies now: it's rumored to top the one and a half million mark.
