FIRST ON FOX: A group of 26 Republican attorneys general have notified the Biden administration they will challenge the latest fuel emissions restrictions, calling a new federal rule "the latest attempt to drive gas-powered cars off the road." 

Attorneys General Russell Coleman of Kentucky and Patrick Morrisey of West Virginia on Wednesday filed a notice in the 6th Circuit that they will file suit against the National Highway Traffic Safety Administration's rule titled "Corporate Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027 and Beyond and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030 and Beyond." 

That rule, which was enacted on Monday, requires car manufacturers to dramatically increase the average fuel economy of passenger cars and light trucks in less than a decade. 

The new regulation imposes "unworkable standards that leverage the weight of the federal government to require auto manufacturers to produce more EVs," the AGs say.

"The forced transition to EVs would bypass the free market while increasing costs on families and undermining the reliability of the electric grid," they said.

"Once again, President Biden’s election-year politics value their nonsensical green agenda over helping Kentuckians put food on the table," Coleman told Fox News Digital

"It’s time for the Biden Administration to hit the brakes on its unaffordable EV mandates, let the free market work and get back to protecting our families."

According to Coleman, EVs account for less than 1% of vehicles registered in Kentucky.

"Congress did not give the NHTSA such power to reshape an industry that would ultimately affect the pocketbooks of consumers — this rule is legally flawed and unrealistic," Morrisey said. "This will undoubtedly cause the United States to be dependent on other nations like China for our energy needs and will undermine American energy security by increasing demand and strain power grids."
