Just as a quick note. I borrowed a HCH from my company motor pool and drove to Southern Pines (near Pinehurst) NC from Chattanooga, TN. I went through Knoxville, Asheville, Winston-Salem on the way. For starters, this is a most Hybrid unfriendly route, next I had my boss and he is used to a Jeep that gets considerably less gas mileage.
On the way over my boss drove 1/3 to 1/2 the way. When he took over the display read 46.1, when we filled up it was around 43. On the way back I drove the entire time and when we filled up the display and calculation was 46.1. I realize this is not good mileage, but considering it was traveling 60-80 (at least on my part) with the air conditioning on the entire time, it was not too bad.
If felt great to get home and jump into a HCH that displayed 55 though
