I understand that you lose efficiency every time you engage the friction brake; however, according to Nissan, e-pedal will (supposedly) only engage the friction brake near the end to bring you to a complete stop. When driving, I do my best to regulate the accelerator that I coast whenever possible.
I much prefer the convenience and experience of e-pedal; however, last night I decided to try driving without it, in D mode after reading other people's reported efficiencies of around 4mi/kwh or more. I've always struggled to consistently reach 4, and typically get 3.5 or below. Last night though, a short trip resulted in an average of 4.7! I was shocked! Outside temp was about 55F, and I didn't run any climate control. Similar conditions with e-pedal usually result in at least an entire mile less per kwh, which seems insane.
Maybe I'm just not as good at coasting as I thought?
