Accordingly, How many MPG does a semi get? Semi-trucks have one to two fuel tanks that hold about 120 to 160 gallons each. If a truck has one tank on each side, it could hold up to 300 gallons of gas. Drivers need to have large amounts of fuel because the average miles per gallon (mpg) for semi-trucks is only 5.6 mpg. On a long route, fuel is consumed quickly.
Why are European and American semis different?
As mentioned earlier, stricter regulations in Europe make for different trucks. For starters, a European semi-truck can only be 18.75 meters or about 61 feet.

Why do American trucks have a nose? This is because the cab-over design has a larger drag coefficient than other designs. In theory, of course, but in practice, there are simply too many variables to take into account to make such a conclusion.
