That all depends on the driver and the route. This test was pretty steady state speed so ECO mode would not be expected to matter.DougWantsALeaf said:Correct, I believe it is not much more then petal remapping. Lower more drawn out draws during acceleration do wonders for range. Same with coasting and trying to time intersection lights (when not holding up other traffic).
I thought it was an excellent (and predictable) test for the un-involved driver who sets the cruise speed and goes. In that situation the heavier car has quite a fuel economy penalty on a mountain route because regen is only ~ 50% efficient.
