Hi Matt,Yep, I've experienced that. Not too many times though, since most of my trips don't involve freeways. Most of my trips are on roads that max out at 60, maybe 65. I'm lucky that way, I can sit and cruise at 60 and get great mileage. That's how I can regularly get above EPA ratings.
I wish more people understood the "highway" EPA rating isn't meant to be achieved at 80mph on the freeway. Be a lot less complaining about not meeting EPA ratings and saying they're "fraudulent" then I think.
EPA rating are done under standard test conditions. They are really for being a compairitor to other vehicles that run under the same conditions. It is remotly likely that you will achieve the EPA ratings. Believe me EPA is aware of this but hard pressed to fix this. They make the rules...then hope for the best...likely a back lash.
How aobut VW, Audi and Porsche that figured out how to determine when a vehicle was under test and provide emission and fuel economy that was not achievable under real world conditions.
Ford was not in the clear, back in 1974...we had a thermal switch in the door jamb of the driver's door that enabled emissions controls only when the switch determined the car was in standard test conditions. Otherwise the emissions devices were disabled. Not against the law until the EPA promulgated the the Defeat Device clauses to the Clean Air Act. Not a sophisticated approach like VW took.
