The average fuel economy number for new, light duty vehicles sold in the US reached an all-time high of 24.1 miles per gallon in October, up from 23.8 mpg the previous month, according to a report released by the University of Michigan's Transportation Research Institute.

That equals a 4.0-mpg increase, or 20 percent, since October 2007, when researchers Michael Sivak and Brandon Schoettle began collecting the data. The number comes from sales-weighted fuel economy calculated from monthly sales of individual models and city-highway fuel economy ratings from the EPA Fuel Economy Guide. It corresponds to a 17-percent reduction in fuel consumption per distance driven, Sivak said in a statement.

The report also updated its national Eco-Driving Index, which estimates monthly greenhouse gas emissions per individual driver in the US. In August, the index reached .81, unchanged from July, but down 19 percent from October 2007. The number is based on vehicle fuel economy and distance driven and has a two-month lag from available published data. You can view the fuel economy graphs and data and the Eco-Driving Index.

US corporate average fuel economy is supposed to reach 35.5 mg by model year 2015 and 54.5 mpg by model year 2025, according to federal standards. The fuel economy numbers are increasing each month, but need to increase proportionally for the mandates to be reached.

      I think 54.5mpg in 2025 is long to go. It will be better to use eco friendly car pollution will be less and environment will also less get hurt. And between the long time we have to use light weight car for less pollution and fuel. It have to be keep in mind less fuel means less pollution and less harm to nature. The big branded care manufacturing company are trying to make more fuel economy car. Toyota, Ford etc these company are trying to build more fuel economy car, it's a good effort.

      I rented a 2013 Ford Mustang (with the V6, being an eco-minded ABG reader) and flogged it through the mountains of East Tennessee and Western North Carolina for the past week. I was exceedingly happy to get an average of 25 mpg over the course of the week, which included a 4 hour drive on the Interstate to and from said mountains at speeds averaging in excess of 80mph. The only way it could have been better was if the Blue Ridge Parkway wasn't closed due to a freak Sandy-induced blizzard, and if I'd been driving a Fisker Karma (which would have gotten the same mpg, but gone the first 40 miles each day on pure battery, meaning that antiquing trip into Elizabethton and the drive up Roan Mtn. would have been purely on electrons). Also, I'll complain bitterly about the 6-speed auto. 300hp and 280ft/lbs of torque really don't need to be constantly searching for the right ratio, Ford. http://i555.photobucket.com/albums/jj456/letstakeawalk42/autos/Mustang_DxO.jpg

        @ Letstakeawalk I recently traveled to Margret River in Western Australia, partly on business, and partly to see my youngest son and his wife. A muddle at the rental agency prevented me from renting my usual Hybrid Lexus 4WD, but a mining engineer friend of my son, knowing my passion for Eco-vehicles, challenged me to borrow his brand new Chrysler 300 SRT8 with ( 8-speed transmission). Like a relapsing alcoholic, I found guilty pleasure in the Chrysler's exciting driving experience. The vast, empty highways of this remote part of the world, revived a teenage passion for the type of motoring the Chrysler once represented. For a rapidly disappearing type of vehicle, I was grateful to once again experience, and dinosaur it maybe, the Chrysler is still a very enjoyable vehicle. For such a powerful car, the fuel economy for 900 mile trip, was surprisingly good. ( Ironically, the Chrysler's owner is an expert in automated Lithium and Rare Earth mining. )

      I think we have EPA / window sticker numbers here: "The average fuel economy number for new, light duty vehicles sold in the US reached an all-time high of 24.1 miles per gallon in October, up from 23.8 mpg the previous month" And CAFE numbers here. "US corporate average fuel economy is supposed to reach 35.5 mg by model year 2015 and 54.5 mpg by model year 2025, according to federal standards." I believe 35.5 mpg CAFE is about 26 mpg on the window sticker and 54.5 mpg CAFE is about 39 mpg on the window sticker.

        So we need to get from 24 mpg this year (2013 model year) to 39 mpg in 2025. Thats a 15 mpg improvement in 13 years or 1.15 mpg better each year.

          More importantly most auto makers have a few vehicles that currently get 39mpg. They already have the hybrid/electric tech to make this happen they just need to put these efficient drive-trains in more of the vehicles they sell.

          It isn't so much they need to add the tech to other cars--it's that the other cars are too big & heavy to get there with current tech.

        It is incredible that 2 auto rags do not distinguish between these two figures.

        Really good point, Dave. This article needs a correction.

      If the majority of car buyers stick for low price gasoline engine without hybrid and batteries then i doubt that it will reach this high an average mpg. This law will just drive the cost upward for the poor car manufacturers. You can't make a miracle with just laws, it take a breakthru and the breakthru is hybrid, bev and hydrogen but the majority will just buy good old farted gasoline because it's still the cheapest.

      one way to get better mpg in the usa is people lost the extra weight they have on them selfs.
