I started up the FK to make a short run, I was on 42 EV miles (I keep the battery at 80% full unless I need more) and the ICE fired up on it's own. That's not unusual as I hardly ever use the ICE, so it turns on every now and again. So I head out on my journey and when I reach my destination, 3 miles down the road with AC on, I didn't use any EV miles!
You can't save EV miles over 27 in Sport, but it looks like the car can save EV miles when it internally turns the ICE on. Has anyone else seen this?
