Extreme race cars can run on straight alcohol (as do some cars in countries like Brazil). Probably 80% of the cars and pickups run on gasoline and most of the rest on diesel.
Most common passenger cars run on gasoline. A small minority of cars and most larger trucks run on diesel fuel. In some countries, such as Brazil, a large number of cars run on either a gasoline-ethanol mix or purely on ethanol, as do many racing cars.
