From Nasdaq:

The U.S. Energy Department will soften rules slashing electric vehicles’ mileage ratings to meet fuel economy requirements, after backlash from automakers and unions. The initial proposal could have led to $10.5 billion in fines for U.S. automakers through 2032.

The final rule will gradually reduce the petroleum equivalent EV fuel economy rating, giving automakers more time to adjust. General Motors could have faced $6.5 billion in fines under the initial proposal, but the new rules will ease the burden on automakers.

The Biden administration considered concerns from automakers and the UAW in crafting the final rule to revise EV mileage ratings. Environmental groups also supported the revision to ensure more meaningful improvements in real-world fuel economy.

The EPA will unveil revised vehicle greenhouse gas emissions requirements to ease yearly requirements through 2030. Automakers may produce significantly fewer EVs in 2030 under the new rules, and the final rule will ramp up stringency requirements through 2032.

The EPA is also expected to scale back its proposal to reduce particulate matter from gas-powered vehicles, addressing industry concerns. Automakers objected to the plan to eliminate enrichment, a strategy to boost performance, which is expected to be curtailed or dropped from the final plan.
