Twenty years in the making, the Reva has quietly become the world's biggest selling electric car, with nearly 3,000 already trolling the roads of India and Europe. In London alone, 1,000 of the vehicles are in use. Technically considered a quadricycle, the $10,000 Reva runs on a pack of eight lead-acid batteries—instead of the more widely used lithium ion units—and can drive only about 50 miles on an eight-hour charge. As a result of its popularity, the company plans to manufacture 5,000 to 6,000 more Revas next year.
