Volatile gasoline prices have caused some regulators and carmakers alike to question the cost and effectiveness of current fuel economy standards, with some arguing they are too stringent and others saying they should be even stronger. Fuel economy standards are simply designed to increase vehicle efficiency above consumers’ base preferences.
