...predicts, steel will be largely replaced by tough carbon fibers embedded in resin, called composites--the same stuff used in skis and racing cars. Weighing less than half as much as today's models--and more aerodynamically designed--advanced cars will be much more fuel efficient. Current models expend about one-third of their power just cutting through the air. In the future, underbodies will be smooth. Headlights and windshield wipers will fit seamlessly into the body. Tiny video cameras and interior TV monitors will replace side-view mirrors. Better onboard computers will improve everything from engine performance to braking...
