March Sales-Weighted Fleet MPG

Compared to March 2010, Ford enjoyed the greatest improvement in sales-weighted fleet MPG in the US market on an adjusted (EPA) basis. But the new king of efficiency, Hyundai, also saw its fleetwide efficiency improve, rising to 26 MPG, some 1.9 MPG better than the next closest competitor, Honda. No wonder the Koreans are the first (and only) automaker to disclose its CAFE fuel economy (as well as the first automaker to publicize the difference between CAFE ratings and the adjusted numbers you see here). For the first quarter of this year, Hyundai’s CAFE rating (as calculated by the automaker) stands at 35.8 MPG, with some 22 percent of its sales mix coming from vehicles rated at 40 MPG on the highway (28% for March).

    With gasoline prices trending upward, an ever increasing number of US consumers will opt for cars with that on are dealer lots that come with 4 cylinder versus a V6.

    Anyone care to speculate why Toyota's numbers trended downward in March -- both car and trucks with cars dipping slightly more? With the latest Prius having a higher EPA rating than the previous generation and, (presumably) selling well, one would expect them to be in line with the rest of the industry.

      The 2010 Prius was out in March. So that wouldn't have any effect on the numbers. My guess is that they sold less Prius and Corolla this month.

    Is it true that the 'TrueMPG' is calculated based on EPA figures as shown on window sticker? (At least that's my understanding.) Unfortunately the so called 35 MPG mandated for 2016 is NOT based on EPA window sticker figures.
