TrueCar Presents Sales-Weighted (EPA) Fleet Fuel Economy

Hyundai may have taken the unprecedented step of publicizing its sales-weighted Corporate Average Fuel Economy (CAFE) number, but as the Korean automaker itself has pointed out, CAFE numbers are based on unadjusted (non-EPA) numbers that do not reflect window sticker ratings. Into that gap step the auto data-philes at TrueCar, who have created the first index of sales-weighted EPA fleet fuel economy for the US market. According to TrueCar’s release

TrueCar is seeking to provide transparency and truth in average fuel economy, providing an alternative view to Corporate Average Fuel Economy (CAFE) ratings that can be confusing and misleading. TrueCar’s monthly average fuel economy helps keep in perspective what each manufacturer’s average miles per gallon per car sold using EPA’s window sticker.

Unsurprisingly, Hyundai takes the top average efficiency rating, at 26.6 MPG, while Chrysler trails the pack at 19.5 MPG. More surprisingly: Toyota’s car fleet became 1.6% less efficient in the last year but still held onto its lead at 28.7 MPG. Also, GM’s truck fleet actually became less efficient over the last year, even as Ford and Chrysler’s trucks improved 1.1 and .6 percent respectively. For more fleet average breakdowns by segment, just hit the jump.

    Another note... Isn't this what the new regulations will be based on, sales dependent corporate average of the entire fleet, but using CAFE numbers? Looks like sales trends with gas prices are going to weigh in heavily. Toyota took a hit probably because it sold less Prii. GM probably took a hit because sold more large trucks than it did previously. Obviously Toyota and GM both are making more fuel efficient vehicles, but sales trends have a huge impact on this for all auto makers.

    Wow, not much difference between the small and midsize industry averages.

      Yup and spent 600+ miles behind the wheel of a 2007 Chevrolet Equinox 3400 AWD with 40,000 miles on it. Plenty enough seat time for a "Time Capsule Review" if anyone is interested.

    Yet again, Ford is behind GM.
