The 2025 Corporate Average Fuel Economy (CAFE) rules require a manufacturer's average fuel efficiency to be 54.5 mpg or above by 2025.
The rules do not apply to trucks, which will meet a different set of rules, and vehicles are expected to meet efficiency targets on a steady increase up to 2025.
As Wards Auto reports, NADA worries that the vehicles produced to meet the rules won't be of interest to buyers, who may be put off by the higher prices the extra technology will result in.
"It will create a jalopy effect," says NADA Chairman Bill Underinner, "where people hold onto their cars for longer because they don't like what's being sold.
"It's going to be very hard for the manufacturers to build cars the public wants to get 54.5 mpg."
NADA is supporting new legislation introduced last month by Congressman Mike Kelly (R-PA), demanding a safety and jobs analysis of the new gas mileage rules. Many worry the new rules will harm the market enough that job losses will result.
NADA is also concerned about increased prevalence of OEM-mandated upgrades to dealerships. Underinner says that not all dealerships can afford the property upgrades--while those that can, risk customers thinking they're being overcharged for their cars, if a dealer can afford millions in renovations.
In the end, it's up to the customers themselves. There are plenty of customer benefits to the 2025 rules--but will buyers see it that way?
