The University of Michigan Transportation Research Institute’s monthly United States new-car fuel economy report is out, and it’s a doozy: August 2014 saw an all-time high of 25.8 mpg.

Automotive News reports the figure is the highest recorded since UMTRI began calculating averages in October of 2007, when the average then was 20.1 mpg. The most recent peak came in May, when the average was 25.7 mpg before dropping to 25.5 mpg the following month.

As for greenhouse emissions, the institute’s Eco-Driving Index fell to 0.78 in June, tying the record low first calculated in November 2013. The metric posits the lower the number — beginning at 1 in October 2007 — the lower the emissions.

    I do think the mpg should be removed from the graph and a number as a measure or value of new cars sold with the CAFE number given. I have read that owners' of pickups, like the Pentastar Ram are returning a real life FE average of between 16-17mpg. The same goes for the Eco Boost F-150s with around the same or a little less. I have also made this comment before and the fanboi's always manage to maintain the manufacturers' FE. But yet they describe how fast their trucks accelerate...Hmmmmm??? I see a lot of debating using the manufacturers figures during debates on FE. But these figures are far from accurate. I have read that diesel FE figures are the most reliable and much closer to the what the CAFE or EPA figures are.

    I'm quite sure 25.8mpg has been regarded as a 'gas guzzling dinosaur' in most of Europe for at least 25 years by now. Seriously, people wonder how I can afford to run my CR-V, and it averages roughly 24mpg. On the other hand, most people do buy underpowered boring diesel wagons over here. Again, people wonder why I need that huge 150 hp 2 liter engine... A V6 Accord would be considered a (very cheaply assembled) luxury racecar over here (and would be taxed as one too).

      @highdesertcat Why are you running everything on 91 octane?

  • Probert A few mega packs would probably have served as decent backup.
  • Lou_BC Lead sleds. Now-a-days GM would just use Bondo.
  • Jrhurren This is a great series. Thanks Corey
  • Tane94 Not as stylish as the Soul which it is replacing but a practical shape and bonus points for EV only.
  • Ronin What is the magical white swan event in the foreseeable future that will suddenly reverse the trend?Success tends to follow success, and likewise failure. The perception, other than among true believers, is that e-cars are a lost cause. Neither government fiat, nor government bribery, nor even the promise of superior virtue among one's peers have been enough to push past the early adapter curve. Either the bust-out is right now for e-cars, or it doesn't happen. Marketing 101.Even subtle language-manipulation, such as deeming those possessing common sense as suffering from some sort of vague anxiety (eg, "range anxiety") has not been enough to induce people to care.Twenty years from now funny AI-generated comedians will make fun of the '20s, and their obsession with theose silly half-forgotten EVs. They will point out that, yes, EVs actually ran on electricity generated by such organic fuels as coal and natural gas after all, and then they will perform synthesized laughter at us.
