Yes, exactly. Yesterday on a very flat stretch, with a warmed-up vehicle, running for 10+ km, 350 m elevation, tires aired up over 40 psi, no traffic, no notable weather/wind, #2 petrodiesel, empty vehicle, half tank of fuel, cruise control set to 104 kph, I was seeing 9 to 10+ L/100km (call it 23 to 26 mpg). The EVIC display never once dropped to 8 L/100km over that stretch.
Now, maybe it was doing a regen, but that's fairly par for the course in my experience. In terms of having it checked out, my experience with dealers is that if there is no MIL lit they just tell you it's operating normally, and I have nothing to point to as overtly malfunctioning. It seems like the extra energy would show up someplace if this were the case, friction losses causing abnormally high heat readings, mechanical sounds, something.
The only way I got higher values on the rest of the run was using ACC (set to 1 bar following distance) to draft tractor trailers the entire time. So, not a real comparison, but a nice hypermiling application for ACC nonetheless. The adage about the view never changing if you aren't the lead dog definitely applies, though.
