A couple of other folks and I seem to have independently concluded that Eco vs. Normal mode doesn’t seem to make a lot of difference to EV range. I’ve more or less switched over to Normal mode since we all made that observation. However, I recently took a road trip — 200 miles each way, so ran out of battery pretty quickly. Soooo, had to do some bumper-to-bumper, stop-and-go traffic in HV mode. I concluded that, unlike in EV mode, Eco was considerably more economical than Normal in the usage! More specifically, I found that it was considerably quicker to fire up the ICE even on the relatively mild accelerations of stop&go traffic, and that it tended to keep the engine on for a considerably larger percentage of the time as a whole.
