The Trump administration shook the automotive industry on Wednesday with its announcement to lower fuel economy standards for cars and light trucks in the United States. President Donald Trump, flanked by CEOs from Ford and Stellantis, proposed a significant rollback in fleet-wide fuel economy to 34.5 miles per gallon for 2031 model-year cars. This decision starkly contrasts with the previous administration’s mandate of achieving 50.4 mpg by 2031.
Under the Corporate Average Fuel Economy (CAFE) Standards, the National Highway Traffic Safety Administration oversees fuel economy regulations, which dictate how far vehicles must travel on a gallon of fuel. In 2024, automakers surpassed the requirement of averaging 30.1 mpg across their fleets, achieving an impressive 35.4 mpg, as per CAFE calculations.
In a surprising move, President Trump also mentioned authorizing the Department of Transportation to permit automakers to manufacture “really small cars,” reminiscent of those found in Japan and South Korea. The administration justified this decision by claiming that existing regulations would have led to a $1,000 increase in automotive prices per vehicle. However, data shows that since the previous rollback of fuel economy standards, the average price of a new vehicle has soared above $50,000, as automakers shifted their focus towards SUVs and discontinued low-end models.
Despite the administration’s assertion that lower fuel economy standards align with consumer preferences, recent trends indicate a growing demand for hybrid vehicles. Hybrid sales have seen a significant uptick this year, with a 6% increase in October alone, showcasing a continued momentum for cleaner and more efficient vehicles.
Experts remain skeptical that lowering fuel economy standards will have a substantial impact on new vehicle prices, as many vehicles are designed with global efficiency standards in mind. Gina McCarthy, former EPA administrator, criticized the administration’s decision, warning that it could hinder the country’s competitiveness in the global car market and technological innovation, potentially ceding ground to countries like China.
Since the passage of the One Big Beautiful Bill Act, which removed penalties for automakers failing to meet fuel economy targets, the standards have been rendered toothless. It is speculated that the administration’s move to lower fuel economy standards may serve as a barrier for future administrations looking to reinstate stricter regulations.
While some automakers have embraced the shift towards gas-guzzling vehicles, others like Hyundai remain steadfast in their commitment to electric vehicles. Hyundai’s sibling company, Kia, has even offered significant discounts on its EVs, signaling a continued dedication to the electrification of vehicles in the face of changing regulatory landscapes.
