With only 250 miles on it and I've warmed it up a couple of times it is hovering at about 12.5 mostly city driving and The manual says to accelerate briskly some to help with break in. So the answer is I don't really know what it will end up being but I'm guessing 15 or so. Not nearly as good as the Durango but I can tell you this it doesn't take long to go from 40 to 70 in a 4 x 4.
