…Americans are buying more fuel-efficient cars. According to the Transportation Research Institute at the University of Michigan, the average combined window sticker fuel economy of cars sold in January is 24.5 mpg, up 22 percent from October 2007. Emissions of that average new car have improved 18 percent since that time.

“We have made relatively huge improvements in vehicle fuel economy over the past five years,” the university’s Michael Sivak told me.”This is especially the case in comparison to the small improvements over the previous 85 years.”
