Proposed mandates for automakers to meet stricter fuel-economy and safety standards in the U.S. would depress sales to consumers and employment in the industry by increasing the cost of vehicles, a research group said today.

The average vehicle cost would rise by more than 22 percent if the U.S. implements its most stringent emissions proposals for 2025, according to the Ann Arbor, Michigan-based Center for Automotive Research. The group’s cost-increase estimates, which account for consumers’ fuel savings from improved efficiency, shrink to 10 percent if gas prices double in that span, reported Bloomberg.

Automakers in the U.S. may be required to almost double vehicle fuel economy to more than 60 mpg by 2025, the Obama administration said in October. Auto-safety regulators proposed requiring backup cameras earlier this month and may also mandate additional air bags and technologies that alert drivers before potential crashes, according to the study.

“These mandates are considered by us to be a considerable challenge,” Sean McAlinden, chief economist for the group, said today in a presentation in Ypsilanti, Michigan. “We recommend a more serious consideration of likely future costs of these new technologies and moderation in the formulation of mandates to reach certain policy objectives.”

The study assumes automakers will use a combination of cheaper methods to improve fuel efficiency such as weight reduction, smaller engines and turbochargers, and more expensive technologies such as hybrid and electric powertrains.

Older Fleet

The more expensive technologies are also the most effective in helping automakers achieve fuel-economy targets, adding costs for manufacturers, the group’s researchers found.

More expensive autos would lead consumers to defer purchases and hold onto their older vehicles longer, which could lead to higher emissions than if mandates were less stringent, McAlinden said.

Consumers replacing older vehicles with new ones at a slower rate would reduce manufacturing jobs while benefiting aftermarket and auto-repair companies, he said.
