I just finished another 300+ mile trip and got 29.3 mpg averaging just under 70 mph. I think this is a tad better than my old 2011 35d. Regarding torque, yes the diesel had more torque but that was really only felt when towing my 3500 pound boat&trailer. The 35i is SWIFT! There is plenty of torque and it is just SO MUCH more pleasurable to drive, quieter, better sound, and feels much quicker. I think the X5 diesel is not worth the trouble. I have been a diesel enthusiast for many years. But with the recent advancements of gasoline engines I would say that the advantage is in favor of gasoline (petrol) engines at this time for the E70.
