The Alliance for Automotive Innovation said the National Highway Traffic Safety Administration’s (NHTSA) Corporate Average Fuel Economy (CAFE) proposal was unreasonable and requested significant revisions.

The industry group argued the plan would boost average vehicle prices by $3,000 by 2032 because of penalties automakers would face for not being in compliance, adding the figure “exceeds reason and will increase costs to the American consumer with absolutely no environmental or fuel savings benefits.”
