The fuel tank capacity was also the same across the entire F10 line (2009) (523i / 528i / 535i / 550i / 520d / 525d / 530d): approx. 70 liter (see
here).
One exception: BMW M fitted inside the F10 M5 (2012) a bigger fuel tank: approx. 80 liter (source:
here) (even 83 liter according to
some).
So it seems that BMW M did not walk this route for the F90 M5.

Point taken that fuel consumption test results differ if different standards have been applied:
- F10 M5 - 2012 standards: 14.0l/100km urban - 7.6l/100km extra urban - 9.9l/100km combined;
- F90 M5 - 2017 standards: 14.2l/100km urban - 8.2l/100km extra urban - 10.5l/100km combined.
But are you suggesting that the fuel consumption of the F90 M5 is that much improved that you can clock more miles with it compared to the F10 M5, despite having approx. 12 to 15 liter less fuel on board (approx. 68 liter instead of approx. 80 to 83 liter), when driven in exactly the same circumstances ? In other words: has the F90 M5 a better fuel range than the F10 M5 ? If affirmative, then definitely kudos to BMW M.

So that pic is actual level by coincidence including estimated range calculated from the previous hours of quite fast operation. |
Locked or unlocked, spirited driving or max eco-style driving: the point made was that the fuel range figure would be
indisputably higher if the F90 M5 would have gotten a fuel tank with a similar size to the one of the F10 M5, instead of one with the fuel capacity found inside the G30, the F10 5er (non F10 M5) or the E60 M5.
