Gas Mileage

Pickups trucks continue to lag other segments of the market in terms of efficiency improvements. When will they catch up?

With Honda's two-motor hybrid system, the 2021 Insight hits a high in city driving and is shaping up to be the highest mileage sedan without a charge port.

Although Fiat Chrysler sold a higher rate of hybrid vehicles than any other automaker, it came up last in fleet fuel economy. How'd that happen?

Some traditional internal-combustion components, like transmissions, could use a rethink yet—with more smarts, not more gears.

If you can't (or don't want to) plug in, the 2020 Highlander Hybrid is the most fuel-efficient way to carry up to eight people.

Until electric trucks arrive, the Ram EcoDiesel is the way to haul heavy loads without guzzling fuel at alarming rates.

The push for higher-mileage new cars isn't as controversial as the federal government might be making it sound.

About 98,000 VW, Audi, Bentley, and Porsche vehicles allegedly game federal emissions tests used for fuel economy calculations.

Automakers (17 of them) wrote a letter to President Trump asking for California to be included in his single national standard for revamping fuel economy rules.

With electric pickup trucks from Ford, GM, and others—including newcomers like Rivian—looking likely to arrive in the next few years, the truck field could be on the verge of a clean, quiet, tailpipe-emissions-free shakeup. That said, you wouldn’t know this segment as being poised...

Yesterday, when we brought you our 2019 Toyota RAV4 Hybrid first drive review, we missed one very important point. At 39 mpg, the RAV4 Hybrid is now the highest-mileage sport-utility vehicle (as the EPA lists them) without a charge port. All the more impressive is that it’s not a low...

Rather than continue to ratchet standards up to 54.5 mpg by 2025, as the current law requires, the new proposal would stall out fuel economy increases at just short of 42 mpg in 2020, and hold them there through 2026.

Though sedans might lack the high seating position of crossovers, the Camry remains proof that they’re more stable, quieter, and guzzle far less gas. They’re also cheaper.

As the industry marches toward greener cars, battery and hybrid drivetrains are expanding into vehicle segments never before concerned with fuel economy ratings or much with emissions. No segment is excluded from this progress, not even luxury grand tourers. Toyota, along with its luxury division...

The four choices included are: The same as set by the Obama Administration (59.4 mpg), an even higher level, the minimum 35 mpg required by Congress under the 2007 Energy Independence and Security Act, or at some lower level down to and including repealing Corporate Average Fuel Economy rules...

While plug-in electric cars are steadily growing in sales, they still pale in comparison to the hundreds of thousands of compact crossover utility vehicles sold each year by virtually every major carmaker. In 2017, Toyota's most popular vehicle became the RAV4 small SUV, supplanting the Camry...

Two years ago this month, Fiat Chrysler Automobiles essentially threw in the towel on the "automobiles" part of its name. Canceling the compact Dodge Dart and the mid-size Chrysler 200 sedans, the company doubled down on the pickup trucks and utility vehicles that had long been its profit centers...

Journalism as an industry is under great pressure these days. There are far more people writing "content" than in past decades, and in general they are having to produce more of it for less money than they did 10, 20, or 50 years ago. That's no excuse, however, for getting the basics wrong. DON'T...

The automakers claimed that the standards were unrealistic given that consumers are flocking to crossovers and pickup trucks as gas prices remain low. According to a new report by the American Council for an Energy Efficient economy, and to our own analysis, trucks aren't the reason.

EPA administrator Scott Pruitt said yesterday the agency plans to modify rules limiting carbon-dioxide emissions for light-duty vehicles in model years 2022 through 2025. The agency, he said, had reached a determination that the limits put in place in 2012 under the Obama administration were...
