There seems to be an almost direct correlation between fuel prices and fuel economy, at least in terms of the mileage of the vehicle the average American motorist has been purchasing this year. And with fuel prices once again starting to rise after unexpectedly tumbling for several months that means fuel economy is heading up, as well.
After a three-month drop, fuel economy of all new vehicles sold in the United States leveled off in July, according researchers at the University of Michigan Transportation Research Institute. Mileage hit an all-time record in April as U.S. fuel prices started racing towards record levels, as well.
For July, unadjusted Corporate Average Fuel Economy, or CAFE, performance was 29 mpg, the same as in June and an increase of 17%, or 4.3 miles per gallon, since October 2007.
