The University of Michigan Transportation Research Institute says the U.S. new car fuel economy average climbed 0.3 mpg to 25.4 mpg in March.
Automotive News reports the average is the highest recorded since the university began collecting data in October 2007, being 5.3 mpg higher than the first recorded average that month. The institute’s Eco-Driving Index held at 0.80 in January, a 20 percent improvement since the EDI was also established in October 2007.
As for fuel consumption, a separate study found consumption to be 11 percent lower in 2012 than in 2004, reflecting both a decline in driving distance, and an increase in fuel economy. In 2012, the average per vehicle was 529 gallons.
