The Environmental Protection Agency and the Department of Transportation unveiled new fuel economy window stickers Wednesday. You will see them on all new vehicles beginning with the 2013 model year. Simply put, the sticker will, for the first time, estimate annual fuel costs and the vehicle's overall environmental impact.
Original designs included a letter grade from A to D comparing a vehicle's fuel economy and pollution impact to those of other cars, but the EPA and DOT rejected the letter system due largely to pressure from automakers. Instead the label will include a greenhouse gas rating and a smog rating. The sticker will also include an estimated annual fuel cost based on 15,000 miles traveled at a fuel price of $3.70 per gallon. It will also estimate how much fuel the vehicle should need to travel 100 miles.
