Saving gas: Less driving, better fuel economy

Monday, November 18, 2013

ANN ARBOR—Fuel consumption by American drivers of light-duty vehicles is down 11 percent since 2004, says a University of Michigan researcher.

In a follow-up to two reports released earlier this year, Michael Sivak of the U-M Transportation Research Institute examined recent trends in fuel consumption by cars, pickup trucks, SUVs and vans in the U.S. fleet from 1984 to 2011.

His findings show that 123.9 billion gallons of gasoline were consumed in 2011, compared with a peak of 138.8 billion gallons in 2004. During the five-year period of 2002-06, U.S. drivers used an average of 135.5 billion gallons of gas annually, but from 2007 to 2011, the average dropped to 123 billion gallons.

"The decline of 11 percent since 2004 reflects the decline in distance driven and the improvement in vehicle fuel economy," said Sivak, a research professor at UMTRI and director of the Sustainable Worldwide Transportation research consortium.

In addition to total fuel consumption, Sivak examined fuel-consumption rates per person, per licensed driver, per household and per registered vehicle. He found that all four rates were 13-to-17 percent lower in 2011 than in the peak year of 2004.

Annual fuel-consumption rates for 2011 were 398 gallons per person, 585 gallons per licensed driver, 1,033 gallons per household and 530 gallons per registered vehicle....
