I have just realized that there doesn't seem to be any basis for the information given by Ford in Norway for estimated driving range. E.g. The First Edition is supposed to have a driving range of up to 540 km, and the RWD ER up to 600 km. Ford in the US says 270 miles/300 miles respectively, which amonut to 432/480 kilometres. Does anynone have a clue as to the rather large difference in estimates betwen the US and Norway?

Likely due to the difference between EPA and the WLTP cycles, which tend to give higher ranges.

OK, that I can understand. But what can we expect when it comes to range - the EPA or the WLTP figure? The difference amounts to more than 100 kilometres ....!

I think that depends on how/where you drive. The EPA testing method I think is more tilted towards highway driving. WLTP method puts more emphasis towards stop and go city driving than highway. So if you drive more high speed and less start/stopping... maybe look more towards the EPA estimates (or less). If you do more city driving, stop and go, then lean towards the WTLP estimates.

EPA is usually considered more accurate, but it really just depends on your driving patterns. If your driving tends to include more high speed and longer distances (which tends to be the case in the US, Canada, Australia, etc), then EPA should be closer. But if you tend to do mostly lower speed city driving and mid-speed country road driving, WLTP may be closer.

A lot has been written on which is more accurate. It largely depends on your driving.
EPA gives more weight to highway cruising and the WLTP cycle gives more weight to short distance driving, which tends to be more "European".

Edit: It looks like we have a consensus from everyone posting at the same time. Clearly we're not lawyers or three of us would've given different answers to the same question.

It is very unclear, on some cars the difference is less than 10% on others it is more than 20%, the manufacturer can choose to use a lower EPA value...personally i prefer EPA (i calculate EPA minus 5% or WLTP minus 15%)

Cold weather also takes a pretty big hit on range. So for Norway, I'd pretty much ignore the more generous WLTP completely and target the more conservative EPA numbers.

Here's another way to look at it... Out of the wide range of BEV efficiencies that vary so much with driving conditions, think of the WLTP as the upper range (i.e. under ideal BEV conditions), EPA as the midpoint (average conditions), and then subtract another 30% off EPA for poor BEV driving conditions (cold weather, high speeds, heavy use of climate control, etc).

In Norway the maximum speed is lower on most routes...
Speed limits seem to be mere suggestions here in the US.

I only do 5 over the speed limit, except in Detroit where the limit is 55 and everyone does 75, there I'll do 65 so I don't get completely run over. Everyone but the semi trucks passes me.

Nor are you scientists as three of you would have given at least four different answers. ?

Ah so you're the guy I keep passing!
