What's at stake, they say, is no less than the future of automotive technology, a practical solution for driving fast and fun with no direct pollution whatsoever. GM agrees that the car in question, called the EV1, was a rousing feat of engineering that could go from zero to 60 miles per hour in under eight seconds with no harmful emissions. The market just wasn't big enough, the company says, for a car that traveled 140 miles or less on a charge before you had to plug it in like a toaster. Some 800 drivers once leased EV1s, mostly in California. After the last lease ran out in August, GM reclaimed every one of the cars, donating a few to universities and car museums but crushing many of the rest. Enthusiasts discovered a stash of about 77 surviving EV1s behind a GM training center in Burbank and last month decided to take a stand. Mobilized through Internet sites and word of mouth, nearly 100 people pledged $24,000 each for a chance to buy the cars from GM. On Feb. 16 the group set up a street-side outpost of folding chairs that they have staffed ever since in rotating shifts, through long nights and torrential rains, trying to draw attention to their cause. GM refuses to budge. Toyota is aware of a growing fad among do-it-yourselfers who put a new battery in their Prius so it can be plugged in at home and then travel about 20 miles on electric power alone.
