I drive iv80 lounge, and had for 3200 miles / 3 months.
As per previous comments:
AC / heating drops range by 10-15% - I open windows to cool down / demist windows!
motorway driving I get 3-3.2kWh - driving like I used to in my BMW 5 (not quite typical BMW driver, but close
)
around town / city 4.0kWh
Driving at this time of year in sunny Yorkshire
