Better gas mileage is great, but Michigan Sen. Carl Levin is bigger on new fuel technology. And he shows it on the road. The Motowner, who used to drive a Ford Escape hybrid, now rides in a Chevy E85 Impala, which runs on a fuel mix of 15 percent gas, 85 percent ethanol. "I just drove it here from Michigan," he tells us. "Well, my wife did." The Democrat says, "I bought it because it's an E85," but he concedes that the fuel isn't easy to find. "You just have to know how and where to find it," adds Levin, who is a fan of spending money to develop alternative fuels.
