What’s handy with the m/KWh figure is if you go for a test drive, zero the display and drive like you normally do for a nice long hour test drive, it really annoys the salesman (we did this with the i3 from Exeter we ended up touring around Torbay before going back to the dealer, he kept saying “if you turn right here, it’ll take us back” 🤣) and at the end of the drive you have a good representation of what you will get, then it’s easy to find the range YOU will get from the battery.
