Gas Mileage

The NHTSA under President Biden will resume the higher fine schedule for gas-guzzling fleets approved in 2016. Should they be applied retroactively?

Ford, GM, and Stellantis expressed a “shared aspiration” to achieve 40% EVs by 2030, with a framework yet to be worked out in detail.

A number of environmental groups called for higher targets and fewer loopholes in Biden gas mileage rules expected in the next week.

The 2022 Tucson Hybrid drives better than its gas counterpart and offers great value. But the big question is, how efficient is it? We took it on a pair of drives, one highway focused and one through the city, to find out.

The U.S. EPA is reportedly on the verge of revealing a plan for tougher annual efficiency increases that would eventually exceed Obama-era targets.

With the NHTSA, it proposes to rescind rules that took away California's authority to set its own emissions framework and to mandate EVs.

The EPA expressed "concerns" about the process used to create the Trump-era rules that relaxed fuel-efficiency targets.

The Biden EPA chief plans to restore stricter auto-emissions standards—and perhaps lay out targets for going all-electric.

The electric-truck invasion hasn't yet started. Is 25 mpg the leading edge of pickup truck efficiency?

The Mercedes-Benz GLB isn't an EV, but with the B-Class Electric in mind we couldn't help but wonder: "What if?"

A rare investigation from the EPA's federal watchdog will be conducted over the administration's hasty rulemaking that contradicted its own earlier findings.

The lowest-priced, most fuel-efficient models from Toyota and Honda—two brands that built their reputation on small cars—have been dropped.

The RAV4 Prime offers more electric range than the Ford Escape Plug-In Hybrid and Mitsubishi Outlander Plug-In Hybrid.

The new Sonata Hybrid costs more than the outgoing version, and more than its rivals.

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

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.

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.
