Can any car run on ethanol?
Any car can run on blends of up to 10 percent ethanol, but cars that run on higher blends require a few modifications. Automakers have built about 5 million “flex-fuel” vehicles that can run on E85. Most of them are SUVs and pickups produced by GM, Ford, and Chrysler. The U.S. Department of Energy maintains a list of flex-fuel vehicles.
