I have AWD SE and I've been mainly driving around town in sport mode with iPedal. I was getting 3.6mi/kwh. I wondered if it would be better with L1 and surprisingly got 4.6 mi/kwh on the same route. I didn't realize that the brake pedal also activates regen as well and you can coast more without iPedal and regen to a stop when you gently step on the brakes. Give it a try and see if you get better efficiency with L1 or L2.
