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.
