Gas mileage efficiency is an important consideration for many new car buyers. It’s likely more important for someone buying a Toyota Yaris than it is for the purchaser of a Cadillac Escalade.

But EPA city and hwy mileage average are the most prominent numbers listed on an manufacturer’s monroney sticker.

Someone purchasing a Hummer is as interested in the numbers as someone buying a Honda Insight, but odds are they’ll still look at the averages.
