This is an old discussion so let me just share a few facts.
We took two demo vehicles with more or less same mileage to the km track.Before going we filled both vehicles with fuel and reset the OBC's of both.
Vehicle 1 the F30 320d auto 8speed
Vehicle 2 the F30 3201 auto 8speed
At the track we decided on best of three runs just in case there was a bit of driver error.
Run 1
Pullaway up to 100km/h the 320i is half a car ahead.From 100 to 160 the 320d actually passes and opens up a 2 car lead that it holds to the end of the km.
Run 2
The 320d gets away better and at 100km/h there is no difference.Same again from there 320d forges ahead and ends the km 2car lenghts ahead.
Run 3
The 320d ahead to 100km/h and opens up 3 car lenghts at the km end.
Data reveals that the 320d has done the km runs with exits of 185/185/184.
The 320i exit runs show 183/182/180.
The petrol car seems to have heat soaked more than the diesel car.
We head back to the office and on return the average fuel consumption on the F30 320d reads 5.9 litres per 100km and the F30 320i reads 10.6 litres per 100km.
The facts speak for themselves but at the end of the day you are either a petrol or a diesel person.
