Did 100 mile roundtrip mostly highway, 22" wheels. 344 wh/mi. There was some bad freeway traffic in spots so that helped.
Previous non Raven on 22's always hovered 450+.
Going to throw our spare set of 20's on for a 700 mile roundtrip in a few weeks. Hoping for sub 300 like other's reported. Like @Tjhappel reported, our 3 on 20" wheels gets 270 wh/mi. Pretty amazing considering the weight of the X relative to the 3.
