The chart below can help you see how much money you could save in fuel annually by choosing a more fuel-efficient vehicle. To compare two vehicles that Consumer Reports has tested, first look up their overall miles per gallon in the Vehicle Ratings chart (available to subscribers). Then locate the overall mpg figure for one vehicle on one axis of this chart and the mpg for the other vehicle on the other (it doesn't matter which is which). The box where the two intersect shows how much money you'd save per year, assuming you drive 12,000 miles and gasoline costs $4.00 a gallon. Remember: A vehicle that runs on regular fuel will save you even more compared with one that runs on premium.
