This is an extract from the Autocar test of the revised Polestar 2 which has switched from FWD to RWD
But on our 70mph motorway touring efficiency test, the improvement was 26%. That’s partly because, as EV makers have learned, a car is always more efficient at a steady cruise when being driven on from the rear axle (where the majority of its mass is carried, with more of the drive torque being translated into forward motion) than it is if pulled from the front.
I am not saying it's not true but I wonder why as CV joints are still needed.
BTW I can see the re -run of the " fuel economy lies debate " coming soon.
