Eco, Comfort. Regen. What's the setting to maximize range?

In theory, ECO. However, your driving habits will have far greater effect on range. Setting Eco won’t matter if you set the cruise control to 85mph and constantly accelerate/stop like a madman.

FWIW, we just leave in in Comfort and the estimates on the dash are fairly consistent. This past winter we experienced greater changes in range due to temperature than anything else.
