Gas Mileage

The EPA might give automakers another big break on fuel economy and emissions—in addition to the one they just received in CAFE requirements.

Real driving emissions ratings should be the start of any incentive program aimed at spurring sales, amid a pandemic with connections to air quality.

Car buyers see mileage as an important piece of vehicle selection—with or without the low gas prices.

GM owners could be less likely to buy another product from the automaker because of its position to squash California's emissions rights.

The EPA has released a final rule that will ease the fleet fuel economy requirements and allow higher amounts of CO2 from vehicles.

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.

Instead of doing away with some of the current incentives for hybrids and PHEVs, it might just limit the annual hike to 1.5% through 2026.

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...

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...
