You will get far less EV range on the highway than city driving...especially given the Jeep’s aerodynamic ms. The EV mode energy usage on your 4xe is 3 times the usage rate of my Model 3 Tesla. I bet it actually does good in EV mode while off-roading.Best I got out of the battery is 19.5 miles, and that was 70% highway. I haven’t don’t only surface street driving to find out. And I honestly don’t know for hybrid mpg. I filled up for the first time and this tank of gas will be my test.
