ANN ARBOR, Mich. – The average fuel economy of current model year vehicles is 14 percent higher than just four years ago, say researchers at the University of Michigan.
For all 2012 light-duty vehicles (cars, pickup trucks, minivans, vans and SUVs) offered for sale, average mpg is 21.5, compared to 18.9 mpg for model year 2008 vehicles. The averages were 21.2 for 2011, 20.7 for 2010 and 19 for 2009.
For new vehicles actually purchased, average fuel economy is typically one-to-two miles per gallon higher—22.5 mpg for model year 2011 (the last full year of sales), 22.1 for 2010, 21.3 for 2009 and 20.8 for 2008.
“This implies that consumers tend to choose vehicle models with better fuel economy than the average of all vehicles available,” said Brandon Schoettle of the U-M Transportation Research Institute. “The recent economic downturn, coupled with rising gas prices, has led to an increased interest in purchasing more fuel-efficient vehicles.”
Using data from the EPA, Schoettle and UMTRI colleague Michael Sivak also examined fuel economy changes by vehicle characteristics: cars vs. light trucks, vehicle class size, transmission type, number of engine cylinders, drive type, fuel type and hybrid vs. conventional vehicles.
