This is certainly possible. Here's why. Alcohol has less energy per gallon that gasoline or diesel.(As pointed out above) BUT an internal combustion engine is very inefficient. That is, it converts fuel to things other than propelling the vehicle down the road...like lots of heat, etc.
So, the question then is how to make the engine more efficient. One way is to increase the compressiion ratio. But when you do that with 87 octane gasoline, it can "ping". Pinging is the fuel igniting before the spark plug sparks due to the heat of compression...sometimes called pre-ignition, or detonation.
Enter E85...lower energy, BUT higher octane...about 105 I think. Octane is the ability of a fuel to resist pre-ignition.
Therefore, an engine designed to function on 87 octane gasoline will not be using all of the good characteristics of E85, but an engine designed to use the higer octane E85 will result in higher efficiency, and therefore better fuel economy.
