The proof of the pudding is in the eating. F10 M5 owners who will own the forthcoming F90 M5 will likely share their fuel range experiences over here.

We both know that this is a car enthusiasts forum. No science board. There is some data around and some questions are asked. Logical fallacies, ill-founded reasoning/conjectures, wrong conclusions, etc.: it's perfectly okay to point this out. However, even if you feel offended, appalled or provoked, there is no proper reason to get ad hominem. We're here to discuss topics in a constructive way, rather than in a destructive way.
