Bjørn Nyland did some testing and posted a video, comparing the Wh/(k)m at various speeds for the S, X and I-Pace. He then did more testing to find the optimal driving speed to minimize time driving and charging. I took his data and made a couple of graphs, extending the trend lines a bit in either direction to fill in a bit more data. I used a 2nd order polynomial fit.
Anyway, I thought the data was interesting, although probably not too useful. Have a look.
