(Department of Energy) Choosing a more efficient vehicle? Thinking about buying a new vehicle?
Fueleconomy.gov has gas mileage estimates and other information for cars from the current model year back to 1984.
Selecting which vehicle to purchase is the most important fuel economy decision you'll make.
The difference between a car that gets 20 MPG and one that gets 30 MPG amounts to $612 per year (assuming 15,000 miles of driving annually and a fuel cost of $2.45).
That's $3,062 extra in fuel costs over five years.
