I just bought a 2015 Titanium LWB as the new family hauler for my wife. We only have 2200 miles on the thing. Today we had a 4hour road trip where we took my siblings along. 5 adults, 2 in carseats, so we were pretty well loaded.
I ended up getting 24.5mpg at 75. I haven't verified the trip with a fillups, but id imagine thats close to actual. I also noticed milage start climbing as I hit construction and dropped the cruise to 55.
My big question is, where is the turning point in the milage? 65? With the speed limits all going up to 70, I cant stand the idea of not doing the speed limit on long trips just to get better milage.
