Survey Says Auto Suppliers Back Tougher Fuel-Economy Standards

The U.S. is reviewing fuel-economy requirements that call for automakers to average 50.8 mpg (4.6 L/100 km) in 2025, but automotive suppliers have their fingers crossed regulators won’t change a thing.

In a survey of 25 mostly Tier 1 suppliers commissioned by CALSTART, a national nonprofit organization dedicated to expanding clean-transportation technology, 84% say the 2025 standards encourage job growth in their companies, a 25% increase from a similar survey conducted in 2016.

The CAFE standards are undergoing a midterm review due to conclude April 1, and a rollback in the target is possible under the Trump Admin., which has been moving toward less government oversight overall.

“Automotive suppliers have benefited from strong fuel-economy standards,” says CALSTART President and CEO John Boesel. “The growth these companies are enjoying is at risk if the 2025 standards are rolled back. If there’s one thing these companies need to thrive, it’s consistent, long-term targets.”

Some 80% of the respondents want the current 2021-2025 CAFE targets to remain in place or be strengthened, CALSTART says. In addition, 87.5% say it is important for regulators to begin working now to establish new standards for post-2025.

The survey also found 83% agreed or strongly agreed “companies that are leaders in vehicle-efficiency technology will be more successful over the next 10-15 years.”

Asked to identify the three most important technologies for 2026-2032, suppliers pointed to battery-electric vehicles, plug-in hybrid vehicles and 48V mild and full hybrids.
