Vehicle fuel efficiency nearing goal for 2016
DETROIT— Automakers are making slow but steady progress improving fuel efficiency, as the industry hit a high for the average miles per gallon of new vehicles sold in August in the United States.
A study released by the University of Michigan on Tuesday said that the average fuel economy on the window stickers of cars and trucks sold last month was 24.9 miles per gallon.
That was nearly 5 miles per gallon better than the 20.1 mpg recorded in October 2007, when the university’s Transportation Research Institute began tracking the data.
The improvements reflect broad changes across the industry in the size, weight and engines in new models, as well as an increase in the number of hybrid and electric vehicles on the market.
“Consumers are interested in fuel-efficient vehicles and automakers can make them,” said Don Anair, a green- car expert with the Union of Concerned Scientists.
The car companies are under pressure to increase fuel efficiency to meet strict federal standards for corporate average fuel economy, or CAFE.
But the latest data indicates that automakers are apparently on track to at least meet interim goals agreed to last year in negotiations with the Obama administration.
The CAFE performance of a vehicle is several miles per gallon better than the fuel economy numbers on window stickers of new vehicles.
Last month, the university’s research showed that for CAFE purposes, new vehicles achieved 30.1 miles per gallon, not including credits and adjustments that manufacturers are allowed under the federal rules. Under the new government standards, automakers have agreed to a fleetwide CAFE mandate of 35.5mpg by 2016, and 54.5 mpg by 2025.
Anair said that 35.5 mpg under the CAFE formula was equivalent to about 27 mpg listed on a window sticker. That would make the 2016 goal achievable at the current rate of improvement.
The overall gains in fuel economy since 2007 have accelerated since the U.S. automakers have recovered from the recession.
General Motors and Chrysler both went bankrupt four years ago and needed government bailouts to stay in business. Since then, they have brought out some of their most fuel-efficient models, with GM introducing a seriesofsmall carsthatachieved markedly better gas mileage than its older vehicles.
Ford Motor Co., which was the only Detroit car company to avoid bankruptcy, has also made rapid improvement in the fuel economy of its cars and pickup trucks.
And Toyota, the largest Japanese manufacturer, has continued to expand its lineup of Prius and other hybrid vehicles, which run alternately on gasoline and battery power and are among the most fuelefficient on the road.
One of the University of Michigan researchers, Michael Sivak, said the mileage improvements since 2007 reflected sustained gains across the industry.
“The 4.8 mpg improvement in the source of the past six years is significant both by itself and in comparison to the change in vehicle fuel economy over the past 90 years,” he said.
“For a long time there’s been this notion that a truck is a big brute of a thing and that if it’s fuel-efficient, it can’t do the job,” said Philip G. Gott, an analyst at the research firm IHS Automotive.
“The market is finally beginning to realize that’s not the case.”
