There are a few interesting bits of information in that article: from the footnotes, they state NEDC efficiency of 16.9-16.2 kWh/km for the ID.4, 16.2 kWh/km for the 1st edition, and 15.4 - 14.5 kWh/km for the ID.3 . I know not to trust NEDC ratings, but given the similarity in the drivetrain between the ID.3 and ID.4, I think the ratio between the two cars' efficiencies might be the same in the real world. That would put the ID.4 1st edition about 11% less efficient than the ID.3, which is a pretty efficient car. Also, given the range they listed I would guess that it's the AWD variant with 16.9kWh/km NEDC, which is about 4.5% less efficient than the RWD version.

Bjorn Nyland's efficiency test of the ID.3 gave 135 Wh/km or 4.61 miles/kWh at 90 km/h (56 mph), and 205 Wh/km or 3.03 miles/kWh at 120 km/h (75 mph). Scaling by 14.5/16.2 that suggests 4.13 miles/kWh at 56 mph and 2.71 miles/kWh at 75 mph. That would be about 318 or 209 miles at 56 or 75 mph, respectively.

I have arrived at similar numbers as you, based on WLTP ranges for both cars and Bjorn's and others tests.

Thanks for sharing, but this seems specific to the European-spec (since it’s referencing the Max, which isn’t a trim in N. America).

If that is true, then I will be very disappointed. Do they think Americans are not sophisticated enough to appreciate that refinement?

I am looking at both the VW and Nissan Ariya which has e4orce. The Nissan seems to have a similar approach to their four wheel driving dynamics and chassis stabilization as that described by VW, although I don’t remember Nissan mentioning damper modulation. It will be interesting if Nissan puts e4orce in models for the US.

I would love to see head to head reviews of the two systems.

Yes, it's referring to the Max 1st edition, but the powertrain is identical to the 1st edition we will get in N. America. If anything, I would expect the lower trim that we get to be slightly more efficient, since it probably weighs less and has fewer features.

It isn’t a matter of efficiency, but rather the car’s handling dynamics.
