No it would be impossible even with 2WD. The AWD Passport switch to 2WD at higher speeds anyway. I can see maybe 1-2MPG better at most with 2WD but you can’t change aerodynamics with just 2WD.Not buying it. Although my 200 mile round trip was in my sport trim with awd i did the first leg of the trip with the eco and stayed between 60-65 mph and was super easy on the pedal to see what i could get. Mostly flat land and only got 26mpg. The second leg of the trip(back home) was without the eco and driving the same speeds only got 28 mpg.
So are you saying the 2wd would get a lot better mpg then the awd? What would be the details of someone easily getting 40 mpg in a passport? Staying under 45 mph (who does this?) on super flat land?
So far i have only seen two people out of hundreds on this forum claiming 40 + mpg in a passport.
I definitely can but it’s not going to be on flat ground. It’s what it is. I don’t know why people think one’s MPG will apply to other’s. People live in different kind of traffic and terrains.Realistically, I could never reproduce 40.3 mpg again unless all the planets are aligned but I do make an 80 mile, all-interstate trip regularly and I very often get over 30 - 34 mpg in one direction. It has everything to do with the wind resistance. I still remember how hard it was to pedal a bike against the wind then coming home would almost require no effort.
