rulemaking (NOPR) , in which DOE proposed regulations regarding procedures for calculating a value 
for the petroleum equivalent fuel economy of electric vehicles (EVs) for use in the Corporate Average 
Fuel Economy (CAFE)  program administered by the Department of Transportation (DOT). In their 
comments to DOE's NOPR, the Alliance for Automotive Innovation (Auto Innovators) rais ed the issue 
of the ability of manufacturers to comply with the proposed PEF in 2027 due to vehicle design cycles.
