It does say that they averaged 4.2kw though, which backs up what they’re saying.
Where? what’s shown is a prediction, before the vehicle is driven, that will change once the vehicle is driven
actual range can only be measured from a full battery to zero and mileage driven at the end, not the start.
Im afraid this is the trap most EV users fail to see. It is only an estimate based on the past, not what you will get going forward.
