With automakers focusing on the bigger, more powerful vehicles, the Environmental Protection Agency found that average gasoline mileage for 2000 model year passenger vehicles was 24 miles per gallon, the same as last year and the lowest since 1980. The figure had climbed to 25.9 mpg in 1987 and 1988. Those now account for 46 percent of all U.S. passenger vehicle sales.
Light trucks tend to weigh more than cars and get fewer miles to the gallon.
The average 2000 car gets 28.1 mpg, while light trucks get 20.5 mpg. We sell cars that get 40 miles per gallon, but fewer than 2 percent of consumers buy them. But Dan Becker, director of the Sierra Club's global warming program, said Tuesday that automakers spend much of their huge advertising budgets pushing lower-mileage SUVs because they are so profitable. Better gas mileage would reduce oil consumption, lower fuel costs and lower carbon dioxide emissions, he said. Passenger vehicles discharge about 20 percent of the carbon dioxide emissions in the United States.
