What drive mode did you have it set on ? i.e. Dynamic, Auto, Efficiency, Comfort ? I have been mostly doing short trips up till now and its hard to see much diff between them in terms of mileage.155 mile trip from Leeds to Norwich during the day.
3.3m/kwh
Outside temp 6 to 8c
AC on all the way at 21c
All Motorway or A roads and kept to speed limits other than a few overtakes.
Still recording 100 miles range left.
Return trip will be on an evening so be interesting to see what I get on the way back.
