Gas Mileage

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...

The makers of the 2018 Mini Coooper S E Countryman All4, the unwieldy name for its first plug-in hybrid small crossover utility vehicle, aren't going to make any friends among electric-car fans. That's because the company has included in its marketing the notion that the car's hybrid powertrain...

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...

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...

Under the new administration of President Donald Trump, the EPA has reopened comments on its decision to finalize emission rules for 2022 through 2025 vehicles. Meanwhile, the NHTSA—which sets fuel-economy rules that have to correspond to EPA limits on carbon-dioxide emissions—hasn'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...

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...

We've driven a lot of compact crossover utility vehicles in recent months. It's a hot category in the new-car market, with all light trucks getting better fuel economy than in past years—and gasoline prices continuing below $3 per gallon in most of the U.S. So we wondered what readers felt...

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...

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...

Given the current political landscape in Washington, it's not unreasonable to worry about the future of U.S. efforts to combat climate change. The Trump Administration has embarked on an explicit mission to undo all Obama Administration efforts to reduce carbon emissions. Climate-science deniers in...

The auto industry tends to oppose, viscerally and viciously, all attempts to regulate any aspect of its products or business operations for any reason. With President Trump in the White House, the industry has succeeded in getting the comment period reopened for the EPA emission standards finalized...

At the 2017 Geneva auto show, General Motors announced the sale of its entire European operations—comprising factories and the Opel and Vauxhall brands—to PSA Peugeot Citroën. German Opel and its British Vauxhall sibling have represented GM's main presence in Europe for decades...
