Lordstown Motors is entering their truck using 4 Elaphe L1500 motors in a 250 mile offroad race this weekend. https://lordstownmotors.com/blogs/news/score-san-felipe-250-race-truck-a-first-look
This should be an extreme test of the Elaphe in-wheel motor reliability with about double the weight per wheel of the Aptera.
Lordstown had estimated a 3x worse energy usage in off-road racing vs normal street use, but they experienced higher usage especially in deep sand. I would also expect regen to be of limited help off-road with the sand slowing you down for the corners.
