Consumer group cries foul on Hyundai's 40-mpg claim As reference, do see http://priuschat.com/forums/other-c...uth-about-epa-city-highway-mpg-estimates.html about the EPA tests and the last page of http://www.consumersunion.org/Oct_CR_Fuel_Economy.pdf about CR's tests (and the old EPA tests). From what I've seen, CR's city test is pretty harsh usually most cars are well under the EPA city estimate. However, CR's highway result is usually higher than the EPA highway estimate. That's not the case for the Elantra w/the EPA highway rating being 40 mpg while CR got 39. For more numbers available w/o a CR online subscription, see Most fuel-efficient cars, Best & worst cars review, fuel-efficient vehicles and and Consumer Reports - Fuel economy vs. performance (only has overall numbers)..
