The University of Michigan Transportation Research Institute has been tracking the average overall fuel economy of vehicles sold in the U.S. since October 2007, and while the general curve has been towards more fuel efficient vehicles being sold, the opposite happened this past June.
With gas prices falling for this first time in months, consumers are obviously feeling more comfortable buying a less fuel efficient vehicle. The average in June was 23.6 mpg, down 0.1 mpg from May and down 0.5 mpg from the peak in March. Not a substantial amount, but enough to show that fuel economy is a large factor when it comes to buying a new car.
Even the amount of travel Americans are doing is increasing, going up by 0.9 percent in the first four months of 2012 compared to the first four months of 2011.
