In my experience it's more like 4-6 MPG difference.sixtn39 said:And, if the mpg for the Ody is a couple of mpg less I still find it remarkable, if comparing that to the SLK.
I can't say I am a fuel economy expert - but getting 709 miles out of my 12.4 gallon tank Civic is quite an accomplishment. That's irrelevant here though I guess...
My observed difference in FE between the SLK and Odyssey range an average of 15-18MPG overall vs 21-24 overall. IMHO, that's a huge real world difference. Our 2006 Ody had an EPA rating of 20/28 - actually higher than the SLK.
I guess the bottom line is that the Odyssey driveline is EXTREMELY optimized to the EPA testing procedure which, in my experience, does not acutally translate into real world FE. The updated 2008 ratings reflect these differences even less - 17/24 for the Ody and 18/24 for the SLK. The Ody consumes at least 25% more fuel driven in a similar manner and though I would CERTAINLY expect it to. I am just stating that the EPA #s are not nearly reflective of real world #s; unknowing consumers would (should?) expect the Ody's EPA #'s to be closer to reality.
I think I can manage a 500+ mile tank when our family drives down to Disney later this year, and after I accomplish that I will post that update in this thread...
