UMTRI: US new vehicle average fuel economy hits record 24.5 mpg in January

The average fuel-economy (window-sticker) value of new vehicles sold in the US in January reached a record of 24.5 mpg (6.47 l/100km), according to the monthly tally by Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI).

The figure represents an increase of 0.4 mpg from the revised December value and is up 4.4 mpg (or 22%) from the value in October 2007 (the first month of monitoring). The recent improvements reflect the improved fuel economy of the 2013 model year vehicles.

The University of Michigan Eco-Driving Index (EDI)—an index that estimates the average monthly emissions of greenhouse gases generated by an individual U.S. driver—stood at 0.82 in November. This value indicates an improvement of 18% since October 2007. The EDI takes into account 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).

Average fuel economy of new vehicles in the US rose again in November; UMTRI Eco-Driving Index at 0.87, highest since April

Average fuel economy of all new vehicles sold in the United States is up for the second straight month, according to researchers at the University of Michigan Transportation Research Institute (UMTRI). In addition to average fuel economy, Sivak and UMTRI colleague Brandon Schoettle issued their monthly update of their new national Eco-Driving Index, which estimates the average monthly environmental impact of an individual US driver. The EDI takes into account both vehicle fuel economy and distance driven—the latter relying on data that are published with a two-month lag.

During September, the EDI stood at 0.87, the highest level since April. The index currently shows that emissions of greenhouse gases per driver of newly purchased vehicles are down 13% since late 2007.

Average fuel economy of cars, light trucks, minivans and SUVs purchased in November was 22.7 mpg, up from 22.6 mpg in October and up from 22.1 mpg in both August and September.

According to Michael Sivak, research professor and head of UMTRI’s Human Factors Group, average fuel economy of all new vehicles bought last month is at its highest level since May when it was also at 22.7 mpg.

The all-time high of 23 mpg occurred in March of this year. Average fuel economy for new vehicles sold is now 2.3 mpg better than four years ago.
