The U.S. Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) intend to expand the amount of fuel-economy information contained on the vehicle window sticker. Among other changes, the information will now include the amount of carbon dioxide emitted by the vehicle. SEMA submitted comments in favor of incorporating graphics, increasing type size and using other visual tools to help focus consumer attention, a position taken by the automakers.
SEMA opposed an alternative approach of using an A–D letter-grading system as too simplistic. SEMA noted that most new-car buyers will be comparison shopping within a specific vehicle segment. Using 25 versus 28 mpg as an example, under the grading system, both cars would receive the same grade (B). SEMA contends that the consumer can easily distinguish the data (25 versus 28 mpg) and that there would be a better chance of achieving the intended goal of making the vehicle’s mileage rating a factor when selecting a car.
