69kg for a turbocharged 2.0 engine is unrealistic.

base engine + aggregates and other components intake/outtake and so on. 2 cylinders more needs larger and heavier components.
As I said, I drive a 220i and M240i convertible side by side and measured weight is around 80kg more (M240i has sport brakes).
Just checked it:
220i convertible, 2019, M exterieur: 1681 kg
M240i convertible, 2021: 1754 kg, further extras: comfort access, foldable mirrors, Harman Kardon, that's it
From a driving perspective, the car feels far heavier than only this difference, especially in the front, without any doubt. Handling is not comparable.
While accelerating, this truth is the other way around;-)
