Fuel economy continues to be important to most Americans, and a majority support regulations that push automakers to deliver new vehicles that have fewer emissions and cost less to fuel. 96% of American drivers say fuel economy is at least somewhat important to them when considering what vehicle to purchase or lease, and two-thirds (66%) say it is very important or extremely important. Fuel economy is the most common attribute drivers say has the most room for improvement on their vehicle. This result has been consistent across eight nationally representative surveys conducted over nine years. Strong majorities of both Republicans and Democrats agree that automakers should continue to improve fuel economy across vehicle types; that they expect new generations of vehicles to be more fuel-efficient; and that automakers have a responsibility to consumers to improve gas mileage. Almost two-thirds of Americans (64%) agree that the U.S. government should continue to increase fuel-economy standards. Just 27% of Americans agree that automakers care about lowering fuel costs for their customers.
