550km would be real strech may be around 480km, seen few of Bjorn videos where he is done 90km and 120km test on RWD with 404km/289Km (weather was quite cold like -3) similar test on M3LR yeilded 563km/422Km but weather was good not cold. Still I think RWD is a great valueABRP suggests a RWD TM3 will get somewhere like 550 km which is what I would think seeing the LR could get 640km. But who is really going to do 60kmh on such a long drive. Would go crazy. I reckon Bjorn is wasting his time doing these tests, better to keep it real world.
