Gas Mileage

Automakers appear to have united behind a surprising position: reviews of emission rules should not involve scrapping the current standards. The Alliance of Automobile Manufacturers, a lobbying group that represents automakers building cars in the U.S., has suggested the Trump administration should...

Sometimes, when science and technology issues have economic or political consequences, incorrect or misleading information and analyses can be propagated through the media, leading both decision makers and the public astray. A piece published in April by Forbes, covering the effects of the 2022...

It's a technology that's been a sort of Holy Grail in the auto industry for at least a couple of decades. Now Mazda, one of the smallest global automakers, plans to introduce it in a radical new engine to be used in a future Mazda vehicle in 2019. It's called homogeneous charge compression...

The U.S. Department of Transportation said yesterday the NHTSA is preparing to revise corporate average fuel economy requirements for model years 2022 through 2025. The proposed version of those regulations, which was issued by the Obama Administration in 2012, included steady increases for each of...

Not so many years ago, a 1.2-liter engine would only have been found in the U.S. in the smallest and least impressive of subcompact cars. It might have been a 3-cylinder, and certainly wouldn't have had even 100 horsepower. But times change, and engines of that size will soon be found even in the...

Honda's smallest of vehicles—the Fit hatchback—has received several updates for the new model year, its fourth for the current-generation version. The 2018 Honda Fit now has incremental styling modifications, additional safety features, a new optional audio system with Android Auto and...

"I want a fuel-efficient car, but I live in a snowy area, and won't buy one without all-wheel drive; what's the best?" It's a question we hear often. Whether or not you agree that AWD is a must-have in wintry climes, the selection of cars with high fuel economy and AWD is limited. DON'T MISS: 2014...

Purchasing a hybrid vehicle makes for a slightly different ownership experience than a traditional gasoline-only car. There are always a few tips and tricks for owners to return the best mileage and range from electrified vehicles, and now a 2013 Ford C-Max Hybrid owner has shared his secrets...

One of the earliest acts of the Trump Administration was to announce that it would re-examine emission rules finalized by the EPA in the waning days of the Obama Administration. Making good on that promise, EPA administrator (and climate-science denier) Scott Pruitt reopened the commenting period...

What's a truck? If you tell your average suburban family that they're hauling their kids to school and sports practices in a truck, many will push back. "It's an SUV," you'll likely hear, or perhaps, "it's called a crossover"—short for crossover utility vehicle, or a car-based SUV. DON'T...

Today's political climate has made for fluid motion in regulations, and corporate average fuel economy targets haven't been left out. Suppliers and automakers have already begun investing heavily into vehicles to be sold in 2022 through 2025, which will include various fuel-saving and...

The 2017 Hyundai Ioniq comes in two versions: a nationally distributed hybrid-electric version, and an all-electric model that will be sold mostly in California and a handful of other states. There'll also be a plug-in hybrid version coming for 2018. We liked the Ioniq Hybrid when we first drove it...

If you're a journalist, it's almost impossible to ignore political news these days. So if readers can resolutely avoid national and local coverage of politics, consider yourselves lucky. That said, sometimes a new political angle can make a dry story on car-buyer data more interesting than...

The Mercedes-Benz E-Class luxury sedan is hardly viewed as green, even if it'll soon have a plug-in hybrid version offered in small numbers. But driving the most recent generation provides a nice case study of the improvement in gas mileage over three decades of updates to the core product that...

It was one of several common tropes used 10 years ago against proposed regulations to boost average fuel economy. "More efficient cars will have to be lighter-weight, and they'll be unsafe because in accidents, they'll crumple up like Kleenex." Logical conclusion: if you require higher fuel economy...

Barbie never said "Math is hard!" The talking doll did, notoriously, say "Math class is tough!" in 1989, sparking a media firestorm over gender roles in childrens' toys and then a voluntary recall by Mattel for offended parents. Reworded, however, the point remains accurate: many people don't...

For the past few years, plug-in electric cars have gotten more publicity than their small share of the market deserved. That's exactly what had happened to hybrids a decade earlier—and hybrids still outsell cars with plugs, even if they're no longer getting outsize publicity. We've been...

Despite some alarmist reporting, President Donald Trump hasn't abolished the EPA's vehicle emission limits. Nor has he wiped out corporate average fuel-economy rules, set by the NHTSA. So far, he's done two things: signed an executive order reopening the comment period for 2022-2025 EPA emission...

It hasn't been the greatest of years for the Toyota Prius hybrid, the Japanese carmaker's flagship product. The fourth generation hybrid hatchback debuted as a 2016 model into the teeth of continued low gasoline prices, and its radical design language apparently turned off at least some potential...

The 2017 Kia Optima Hybrid is one of a pair of hybrid mid-size sedans from the Korean maker Hyundai-Kia. It shares its underpinnings, though not a single body panel or styling flourish, with the higher-volume Hyundai Sonata Hybrid. We found it to be a comfortable, stylish sedan that gave us good...
