The way you drive, even on flat, no wind, and no turns can drastically effect your wh / miles. I have P85D. 300 wh / mile is what I need to get to get the EPA rated mileage. In 70 degrees, flat, no wind, and no turns, I get 285 wh / mile at 70 MPH. At 75 MPH, it's 300 wh / mile. My wife, on the other hand, on the exact same stretches of commute under the same conditions gets closer to 350 wh / mile driving the same speeds? Why? Because she varies here speed by a few mph constantly. If you watch her on the app, the car constantly accelerates and then decelerates. She's not good at keep her speed the same. Even worse, she's not good at keeping her throttle constant and then NOT below zero when she needs to slow down. If I happen to edge up in speed slightly, I ease off the throttle just enough to coast back down to a MPH or so slower rather than more which will result in regen breaking. So what you see on the app if I drive is a nearly constant orange kw dicharge. Whe you see when she drives is orange to green to orange to green. It's only a few MPH variance but it makes a HUGE difference in the efficiency.
