“Coming Monday”: Trump To Roll Back Costly ‘Green’ Rules To Drive Down Car Prices

All this “green” technology embedded in vehicles over the last two decades, such as automatic stop-start, cylinder deactivation, turbocharging, advanced transmissions, hybrid systems, and other forms of electric assistance designed to reduce fuel consumption and improve miles per gallon, has made the upfront cost of purchasing a new vehicle unaffordable. 

The average price of a new car has exploded to $50,000, making it unaffordable for many working-class folks. Automakers have to abide by Obama-era and Biden-era “green” climate rules because these climate alarmists supposedly sought to heavily regulate the industry under the guise of saving the planet. In fact, overregulation has driven the cost of driving and maintaining these complex machines to unaffordable levels.

The DEF systems for diesel engines pushed during the Obama era have also added repair costs, maintenance requirements, and costly downtime. Many diesel owners have been infuriated by overregulation of these engines. Talk to any Ford Powerstroke or Dodge Cummins owners; they are no fans of DEF. 

To fix the mess of overregulation and what can only be described as an increase in the upfront cost of new vehicle ownership, as well as thousands of dollars in maintenance bills and headaches, President Trump announced on Saturday that his administration plans to release new fuel-efficiency mandates that roll back costly green mandates.

Trump wrote on Truth Social:

BIG DAY FOR AMERICAN AUTO WORKERS AND CAR BUYERS! I have just approved new Fuel Economy Standards that TERMINATE Sleepy Joe Biden and Pete Boot-EDGE-EDGE’s ridiculous EV Mandate. The Dumocrats cost our Great Auto Manufacturers $Billions, forced Americans into cars they never wanted, and wasted Billions on Chargers that were never built.

These new Standards will take the waste out of building cars in America. That means LOWER PRICES, saving families thousands on a new, beautiful, and safe car — Far better than the Environmental Monsters that we were building heretofore. Every Manufacturer, from General Motors to Ford to Stellantis, has called me wanting to build here, and now they can!

Under my Administration, over $ 100 billion is being invested in American Autos, and that’s just the beginning.

Transportation Secretary Sean Duffy quoted Trump’s Truth Social post on X and responded, “A major victory for America’s auto workers is COMING MONDAY.”

Bloomberg noted, “If the final rule follows December’s proposal, the projected fleetwide fuel-economy average for 2031 would fall to 34.5 miles per gallon from approximately 50.4 mpg under the Biden standards. The final requirements have yet to be released.”

An NHTSA report from last December estimated that the proposed rule could lower upfront vehicle costs by $930, assuming manufacturers pass along the savings.
