I've been following the discussions around the launch of the Tahoe for several months and there has been a fair amount of hype over increased fuel economy (better aerodynamics, DOD, etc). Must say I feel duped over a measly 1 mpg increase in the combined rating.

First off, we don't know yet if the General's combined number was "adjusted" which means it is a real world calculation rather then just simply adding the two and dividing by two.
With DOD, I would imagine that it works at many points in "in-town" situations, BUT NOT when accelerating which is the focus of the EPA city test.
Lets see how this turns out before we jump the gun one way or the other. A 20MPG combined rating is possible depending on real world conditions.
