Trump cancels rule that incentivizes EV production to meet fuel efficiency requirements

The Trump administration announced Wednesday that it is rescinding the rule which?incentivized carmakers to make electric vehicles?to meet fuel economy requirements?by overstating energy savings.

Environmentalists have long criticised the Energy Department's rules for assigning unreasonably high fuel economy values to electric cars, which then are used to calculate fleetwide medians under Federal Corporate average Fuel Economy rules.

After an appeals court ruling in September, the Energy Department announced that it would remove the provision known as fuel content factor and propose further revisions.

Fuel Content Factor

The DOE said that it concluded the fuel content factor to be "illegal" and issued a rule to remove it immediately from fuel economy calculations.

Biden's administration originally proposed eliminating the fuel content from the calculations in 2027. This would have lowered the compliance value for electric vehicles by approximately 70%.

The 'Energy Department' decided to phase it out in 2030, under pressure from the automakers. The automakers had noted that the fuel content factor resulted in an estimated fuel economy approximately seven times higher than what would have been calculated using only the Energy Department’s gasoline-equivalent electricity energy content.

Fuel Economy Values

Environmental groups in the Biden administration argued that the EV mileage calculation should be revised. They argued "that excessively high imputed values for EVs mean that a relatively few EVs can mathematically ensure compliance without meaningful improvement in the average fuel efficiency of automakers fleets."

The Trump administration, in December, proposed to slash fuel economy standards set by Biden?in 2020, as part of a push to encourage automakers to offer gasoline-powered vehicles.

National Highway Traffic Safety Administration has proposed a significant reduction in fuel economy requirements from model years 2022-2031. The National Highway Traffic Safety Administration proposes a 34.5 mile per gallon?average by 2031. This is down from the current 50.4 miles per galon (21.4 km/liter).

Trump signed a law last year that eliminated fuel economy penalties for automakers. The NHTSA confirmed they faced no fines going back to the 2022 model year. Automakers worry that a future administration may reinstate these penalties.

Trump has taken a number of steps that disincentivize EV production and purchases, and make it easier for gas-powered vehicles to be produced. (Reporting and editing by David Shepardson)
