The federal government requires automakers to include information on a vehicle’s energy consumption, along with pricing and other information, on the so-called “Monroney” sticker that’s posted on every new light-duty vehicle sold in the U.S. It’s named for Almer Stillwell “Mike” Monroney, a U.S. Senator from Oklahoma who sponsored the Automobile Disclosure Act of 1958, which mandated the use of price stickers.
