Fuel Efficiency

So-called "gasoline-burdened families" are paying a huge portion of their income toward gas vehicles and could greatly benefit from a switch to EVs.

EVs aren't mandated by the set of rules proposed by the EPA Wednesday, but they will almost certainly offer the easiest path to compliance under extremely strict new requirements.

The California Energy Commission (CEC) wants replacement tires to be as efficient as original tires.

In an unusual instance of industry speaking up for stronger regulations, a handful of automakers are testifying with California.

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.

Real-world fuel economy of light-duty vehicles sold in the U.S. remained flat for the 2021 model year, at 25.4 mpg, according to the report, and the shift to SUVs plus relaxed Trump-era fleet rules may be to blame for this.

Russia's invasion of Ukraine and the resulting economic uncertainties have accelerated the timeline—leading to more spending on renewables, cleaner EVs, and a "historic turning point," the authority anticipates.

While New York, Washington, Oregon, Massachusetts and others have signed on, Minnesota is a maybe and Virginia's governor is reportedly calling the policy "ludicrous."

The EPA recently announced the levying of millions of dollars in fines against companies for selling equipment designed to circumvent pollution controls, illegal under the Clean Air Act.

California sets more aggressive emissions standards and electric vehicle targets, and it's joined in doing so by a growing group of states.

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.

Texas and 15 other states, along with ethanol groups, have challenged the EPA's emissions rules under the Biden administration

Gas prices are fueling a run on high-mpg models, and to some degree on EVs—and it's exaggerating the supply issues already present this year.

Producers argue that the new rules exceed the EPA's authority because they effectively force automakers to produce electric cars

Environmental groups claim the EPA's proposed standards should do more to encourage deployment of electric trucks.

Here are the widely available cars only fueled by gasoline that achieve 50 mpg combined or more based on EPA ratings. They all start under $30,000.

It stopped buying state vehicles from GM in 2019, when the automaker sided with the Trump administration in a challenge to the state's right to set its own emissions rules.
