Gas Mileage By Car

MPGomatic delivers a unique perspective by providing federal gas mileage ratings along with real world light-footed testing. The historical gas mileage by car data ranges all the way back to 1978 and is presented with the original figures as shown on the window sticker (not the retroactively adjusted numbers).

Car-after-car, our real world reviews have shown that not only is it possible to hit the ratings on the current window stickers, but that you can exceed those ratings under the right conditions with most new cars.

It’s all about when, where, and how you drive.

This page serves as a model-by-model index of gas mileage ratings by car. Our years of testing have shown that the official estimates are only that … and as they often say, Your Mileage May Vary.

If you look at a window sticker, your eyes are inevitably drawn to the big bold city and highway mile per gallon (MPG) ratings. If you look just under those ratings, in tiny print, you’ll see the “estimated range for most drivers.”

The trick is to learn how to drive efficiently …

The 2011 Buick Regal is a case in point. It’s rated at 19 city / 30 highway. We were able to beat the highway number by nearly ten percent, scoring 32.9 MPG … but the Regal’s expected highway range for most drivers runs from 24 all the way up to 36 MPG. If we slowed it down a bit more, we’d probably hit that magic 36.

While the MPGomatic Gas Mileage Calculator does not provide make and model information, you can easily calculate gas mileage by car. Just plug in the fuel economy estimates (or real world results) of two vehicles into the calculator and it will immediately display the cost differences, without fanfare.
