Fuel Consumption Vs Fuel Economy Energy Education The red x is the fuel consumption. [1] fuel consumption and fuel economy are two phrases that are sometimes used interchangeably but have very different meanings. the core difference involves fuel consumption discussing how much fuel a car consumes to go a certain distance and fuel economy measures how much distance a car gets out of fuel. 5.81. 6.8%. this is a chart of average fuel consumption of all cars on the road in the united states, by year. comparing these results to the averages for new vehicles, listed below, there is a large discrepancy. there are three reasons for this. most importantly, new cars achieve better fuel consumption than older cars, and the older cars on.
Fuel Consumption Vs Fuel Economy Energy Education By lori baker. fuel economy is a well defined measure familiar to anybody who has bought a car in the u.s.: it means miles per gallon. fuel efficiency, on the other hand, is a looser, descriptive term referring to how efficiently a vehicle uses fuel, according to john heywood, professor of mechanical engineering and past director of the sloan.

The epa estimates that fuel economy can improve by up to 3.3% by having properly inflated tires, thus decreasing rolling resistance between the tires and the road. [3] this is true for anything with wheels—even peddling a bike with deflated tires is extremely difficult and requires much more energy. the only difference is where that energy.
