Gas Mileage

The vast majority of Americans believe automakers should continue to improve fuel economy, according to the latest Consumer Reports' survey.

Will another wave of surging EV sales prove these standards irrelevant by then, or will automakers make as many gas trucks as they can?

A 2% annual improvement in fuel efficiency is in the cards for passenger cars, and a 4% yearly improvement for light trucks.

GM chose to pay the fines for fuel-economy shortfalls and bank its credits, while Stellantis reportedly says it's doing better now.

The demonstration tire shows Goodyear has the capability to make a tire with 90% sustainable content, even as it aims to launch a production tire with 70% sustainable content this year.

One in 10 U.S. drivers burn 32% of gasoline used in U.S. light-duty vehicles, and these users burn more gasoline than the bottom 60% of drivers combined.

The Sportage Hybrid has recently been rated at up to 43 mpg—beating the most efficient versions of all its hybrid rivals without a charge port.

Well-timed signals can have a significant impact on emissions—equivalent to the CO2 absorbed by a forest 3.3 times the size of Atlanta, according to Inrix.

The mpg standards are a step steeper than an original proposal. Arriving at an effective 49 mpg, they boost fleet efficiency by 8% to 10% annually for model years 2023-2026.

It's been a long time coming. Enforcement had been delayed after automaker lobbying, triggering a lawsuit from California.

By 2026, under stricter rules now written into rulemaking, the EPA anticipates that just 7% of the new vehicle fleet will have “strong hybrid” powertrains, and EVs and plug-in hybrids combined will make up just 17%.

The first version of the Hummer EV "electric supertruck" is too portly for EPA range and efficiency ratings. But GM is releasing them anyway.

Even as the Biden administration prepares for tighter fleet fuel economy standards, automakers' bank of credits could stifle innovation and lower the actual mpg average.

The no-frills, high-mpg, three-wheeled car that's been anticipated for a decade still hasn't arrived, but now the company's decided an electric version comes first.

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

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.

So-called "superusers" should be a target for the shift to electric vehicles, argues the EV advocacy group Coltura.

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