If we told you the average fuel economy and emissions output for all vehicles sold in the U.S. was at an all-time best, that might be no surprise, but the University of Michigan has put specific numbers on these assertions.
According to the University of Michigan Transportation Research Institute (UMTRI), the average new vehicle window sticker mileage was 24.8 mpg. This figure ties those for March, April and May this year, and is up 0.1 mpg from June.
Again, this is for all cars and trucks, not just hybrids and other electrified vehicles and the research was overseen by Michael Sivak, Ph.D., director, Sustainable Worldwide Transportation, and Brandon Schoettle, project manager, Sustainable Worldwide Transportation.
Since Oct. 2007 when UMTRI began monitoring these stats, this average has inched up 4.7 mpg. The average fuel economy for 2013 vehicles sold thus far (October 2012 through July 2013) is 24.7 mpg – up 1.2 mpg from model year 2012 vehicles.
For more details on how calculations are made and the latest mpg values, you can visit UMTRI’s Web site.
As for emissions, the University of Michigan Eco-Driving Index (EDI) estimates the monthly individual U.S. driver’s emissions at 0.81 in April, a 19-percent improvement since Oct. 2007 (the lower the value the better).
Both the fuel used per distance driven and the amount of driving (the latter relying on data that are published with a two-month lag) are taken into account by the EDI.
For more info on the EDI, this too can be found on the researchers’ Web site.
