Coming from an i4M50 to the new i5M60 I am surprised that despite its size and weight increase as well as a little bit more power and torque the i5 is actually easier on fuel and so far it’s returning an impressive 2.9-3.0Miles per KW or approximately 13% better than my i4.
Even on a long journey at a steady 70-75mph it returned 2.9m/KW.
What exactly have BMW changed?
