    So with two whiffs on two car shows. Anyone want to guess which car show is now most likely to see specs released?

    I'd heard that, guess you're right, but it does boggle the mind: fhe fox guarding the hen house? I wonder why? I mean, government crash tests the cars, right? You'd think it would be easy to run independent fuel economy tests on those vehicles first.

    Also, just editorial: "mileage" should read "mpg" or "fuel consumption"?

    I assume that it's the outcome of funding and politics.

    did EPA made any money by busting Hyundai, Kia and Ford?

    The EPA will spot check about 10% of the models of a given year. New models, and high outliers are likely to be picked, so expect the new Prius to be EPA tested. The limit on how many they test has been funds. Their testing facility went years with out a 4WD dyno.

    I believe fines go into the general fund.

    Toyota also said 18% in European spec... of course under European rules... which is perfectly believable since current Auris and Yaris got better MPG than 2009 Prius, so it is around 8-9% better than latest Yaris Hybrid with Prius c powertrain.

    why isn't 18% there the same as 18% here?

    May very well be. But it has been said that the Euro spec is weighed more towards city driving.

    So possible to get 18% city increase with EPA and less on highway. Hoping we will see combined ~18% increase here.

    because test is completely different and can not be compared.

    The NEDC gives results higher than the old EPA.

    For the same reason C has higher rating on non-EPA as Gen3 and opposite on EPA.

    Yes:

    Going from Gen 1 to 2 to 3 combined EPA mpg were 41, 46, and 50, respectively:

    Prius C has the same rating as Gen 3 on EPA. (4% better in town and 4% worse on highway offset)
    Comparing the same car on the City vs Highway tests. The Prius C varies approx. 14% and the Gen 3 varies approx. 6%

    Yes
    Prius C: 7 mpg difference between the two tests = 14% of 50 mpg
    Gen 3: 3 mpg difference between the two tests = 6% of 50 mpg
