Seems like a pretty weak claim to be honest. I think it is pretty obvious that maximum range refers to maxium range under ideal conditions and that using more eletronics in the car reduces the range.
Porsche isn't lying about their max speed either, just because you can't reach it with 300kg of load and bad weather.
