It's a mind-bendingly fast supercar: a 2,000-horsepower, shape-changing,
350mph missile. Outrageous? Sure, but cracking the 300mph barrier is inevitable, made possible by new technology and extreme aerodynamics. "Such a car will have to be substantially longer to better control the air flow and high-speed stability," says Steve Saleen, creator of the racecarlike Saleen S7. As the driving environment changes, the car will morph into different configurations--longer for straight-line driving, shorter for curves--and alter wing shapes to modulate downforce. Driving at 350 mph will be far beyond the skills of most drivers, so active suspension, active steering aids, and collision-avoidance systems--the latter imported from the aircraft industry--will ensure that drivers' reaction times won't result in accidents. With such performance and versatility, the car will be a thrill at any speed.
