New York (CNN) — With the Trump administration effectively dismantling automotive emissions regulations, cars on dealership lots could see some changes. Your next car could be bigger, with fewer fully electric options – but it also might be a hybrid.
The repeal of the Environmental Protection Agency’s 2009 endangerment finding effectively terminates the greenhouse gas standards that governed automakers for more than a decade and a half.
The repeal followed Congress’s zeroing out of penalties for violating Corporate Average Fuel Economy (CAFE) targets as part of the One Big Beautiful Bill Act.
The results of the drastic shift fall into two main categories: affecting the kinds of vehicles offered, as well as the technology inside them.
Changes on the dealer lot
“I definitely think the stop/start technology, stuff like that, will probably go away,” said Stephanie Valdez Streaty, director of industry insights at Cox Automotive, referring to technology that turns engines off when they’re idle in traffic and back on when it’s time to move.
Other technologies that could be phased out include waste heat recovery systems that pull heat from the car’s engine to the interior, solar reflective surface coating and high efficacy exterior lights.
But those technologies aren’t going away instantly.
Technologies like start-stop systems “will continue to vary by vehicle and market as the company evaluates consumer preferences, regulatory requirements, and vehicle design,” Ann Marie Fortunate, a spokesperson for Stellantis, told CNN.
Americans could see a priority shift on dealership lots, too. Automakers could churn out the vehicles that aren’t just in demand, but those with the highest profit margins, such as big SUVs.
“(Deregulation) gives the manufacturer some breathing room to really produce more of those more profitable vehicles.” Valdez Streaty said in reference to higher-margin combustion engine and hybrid options, as well as bigger trucks and SUVs that are historically favored by Americans. “I think we’ll start to see more of those on the dealer lots.”
According to Cox Automotive data, full-size trucks are up 14% year over year, full-size SUVs are up 23.9%, and midsize trucks are up 21.2%.
Even before the repeal, many automakers were scaling back their hybrid and EV ambitions over the last few years. Stellantis cancelled its line of Jeep plug-in hybrids earlier this year, and companies including Nissan and Tesla have halted or ended some EV models entirely.
But the regulatory changes do not mean a wave of radically different vehicles will hit dealerships overnight.
The long-term impact is likely to show up gradually in the types of vehicles that will be produced, rather than a complete abandonment of voluntary emissions standards, complete with redesigns.
“The reality is that politics can move much faster than the auto industry. Policy changes tend to influence vehicle production gradually, over multiple model years, rather than triggering sudden price resets,” Valdez Streaty said.
And when policy changes happen, car companies need time to figure out their plans for future products.
“Ford is still evaluating the impacts of (repealing the EPA’s endangerment finding) on our business,” Benjamin Khoshbin, a spokesperson for Ford told CNN.
Electric cars aren’t going away entirely
Automakers have also become wary of diving headfirst into major product line shifts, after electric car sales proved disappointing once the Trump administration eliminated federal tax credits for zero-emissions vehicles.
