Are Cars More Fuel-Efficient? Yes and No. By Peter Whorisky, WashPost, 9/30/10. "As the U.S. seeks to reduce oil consumption, not all the news is bad: For years, automakers have been selling Americans cars with ever more efficient engines. In fact, a car purchased today is able to extract nearly twice as much power from a gallon of gas as its counterpart did 25 years ago. The trouble is that over the same period, cars have become bigger and more powerful. As a result, the average mileage of the cars and light trucks on the road in the United States has barely budged since 1985."
