I found this one late but it was of enough interest I read the whole thing. Our weather just returned to winter mode yesterday so I get to see the LE's AWD send torque to the rear wheels as needed. Today I did something I never do in any car - I idled the engine to get some heat pumping into the cabin. While Idling I brought up the mpg screen and watched the mpg slowly drop from 7 to 4 mpg at which point I got everyone loaded and hit the road. Truly a waste of fuel. I reset the meter and still got 35 mpg by the end of the 60 mile drive.
