EPA Ratings

The FTC is seeking comments on potential updates of its fuel-economy advertising guidelines.

We're often asked why cars sold in Europe seem to be so much more efficient than those on sale in the U.S. Typically, it's accompanied by the mention of some supposedly 80-mpg car sold in Europe--while the best U.S.-market vehicles barely crest the 50-mpg mark. Now, Reuters highlights one of the...

Well, the numbers are in, courtesy of a quickly-photographed window sticker, and now we know the range and efficiency ratings for the 2014 BMW i3 electric car. The EPA-rated range is 81 miles, and its efficiency is a record-breaking 124 MPGe combined (138 MPGe city, 111 MPGe highway). ALSO SEE...

If you're looking for a small hatchback that delivers high gas mileage and almost unparalleled flexibility, the all-new 2015 Honda Fit should probably be at the top of your list. The new Fit has become a more important car for Honda now that it's built in Mexico, and that's reflected in many of the...

You've read the reviews, and it's finally time: You're off to the dealer to replace your old car with a new, much more fuel-efficient vehicle. But then you get to the dealer, and during your test drive, you notice that the gas mileage shown on the car's display is nowhere near the EPA rating...

The 2015 Ford F-150 full-size pickup truck won't be unveiled at the Detroit Auto Show until tomorrow morning, but some details of its innovations to boost gas mileage have emerged already. Ford apparently gave exclusive details to The New York Times, which reports that the new truck will use an...

Diesel engines are now offered in a growing number of passenger vehicles on sale this year and next, especially crossovers and sport utilities. The 2014 Jeep Grand Cherokee EcoDiesel is one of two popular models this year that offer a good test of how attractive buyers find today's modern diesels...

While hybrids are one way to get good gas mileage in a variety of cars, another way is to wring every last drop of efficiency out of new and highly-efficient gasoline engines and transmissions. That's the path Mazda's taken, and it seems to be working. Two overachievers Almost two years ago, we...

Once in a while, we're blind-sided by responses to an article we publish--and we learn something in the process. On December 23, we wrote about ways that the all-new 2015 Ford F-150 full-size pickup truck might get better gas mileage. We learned that at least some of our readers seem to resent the...

The Ford F-150 full-size pickup is the best-selling single nameplate in the U.S. market, so any changes to Ford's premier truck mean a lot. Buyers, dealers, and the whole industry are paying close attention to information about the next generation 2015 Ford F-150, the first all-new design of Ford's...

The Ford Escape, entirely redesigned for 2013, is one of the best-selling entries in the popular category of compact crossover utility vehicles. The real-world gas mileage of the latest Escapes, however, does not quite seem to equal those cars' combined EPA ratings. Ford has put a great deal of...

Almost four years ago, the Ford Mustang was the first car to offer both 300 horsepower and 30 miles per gallon in its an EPA highway rating. How much better will the new 2015 Ford Mustang do? The 2015 Mustang will offer a four-cylinder engine, the model's first since 1993--though the new 2.3-liter...

Your mileage may vary from the published estimates, as all drivers know. But it turns out it may vary more in Canada, whose fuel-efficiency ratings are higher than those from the U.S. Environmental Protection Agency for an identical car. That's because the Canadian authorities use a two-cycle...

Sometimes we get letters from readers asking for advice, or criticizing our reports on gas mileage. We're always happy to hear their experiences--but a bit of perspective is sometimes needed. Reader Marcus Witte recently sent us the following note (we've edited it slightly for clarity): Your review...

The new 2015 Honda Fit will have a combined EPA gas mileage rating of 36 mpg, according to Honda officials.

There aren't many cars like the 2014 Fiat 500L on the market today. It's a tall wagon, not a crossover, because all-wheel drive isn't available. And it shares only a name and an engine with the much smaller Fiat 500 minicar that reintroduced the Fiat name to the U.S. market after a long hiatus...

The 2014 Jeep Cherokee returns significantly better fuel economy than the Liberty it replaces.

Gas mileage has gotten far more important in new-car choices over the last 10 years, and that's not likely to change. But not everyone really understands automobile efficiency--or how to maximize their mileage--and which tactics will really save them money. Here's our cheat sheet. (1) Your driving...

The EPA will release the results of its most recent round of gas mileage test audits, hoping to make the testing process more transparent.
