I'm curious to know how you come to this conclusion? I don't know much about aerodynamics other than at, as a first order approximation, drag is proportional to the SQUARE of the velocity. Driving 887.5 km at an average speed of 66.9 km/h is, afaict, much more impressive than driving 975 km at 40 km/h.
