Ive only ever calculated local and distance journeys, as two seperate entities and always fill the tank before a long journey. If necessary, I can combine for a running average.
On distance journey’s, I always try to ensure Auto mode is selected, as mine no longer defaults to Auto mode on startup, instead EV mode.
Once the battery is depleted, does yours still recharge the battery back to 100%? Mine has never done that regardless whether onbard Nav ior the cars drive assist is used or not, rather it only charges to 25% before doing a short few miles in electric again.
My last journey netted around 48mpg over 180 miles, at a circa 10mph higher speed than you. I understand my calculated overall average mpg will be higher, due to my local mileage but, considering, I fill up before a journey, which resets the cars computer we should be getting similar on longer distance journeys. I just don’t get it mate!
