None of those things should matter as long as you're doing constant steady speed on the same incline with the exception of the A/C which I don't think is actually controlled by the driving mode. The same wind resistance and gravitational force is in effect in both modes therefore the energy consumed should be identical. This is why my question revolved around how is the OP measuring the consumption to see a significant difference between these two modes.It changes the aircon settings too I think this is the main difference plus it limits the pace so the available power is less. Also it will stop you going over 85mph by default.
I would imagine the 10-15% difference is calculated on this basis.
Sure! But the OP asked between comfort mode and dynamic mode.100% it changes the AC in efficency it goes into eco mode. You notice it on a hot day if you flip to efficiency mode.
OP here. I used the short term memory consumption meter measuring KWh/100 km. I was using cruise control going 125 km/hr. Nothing changed other than flipping between Comfort and Dynamic. Gear ratio should not be a factor. I was surprised to see any difference hence the question.Are you looking at the instant consumption meter bar? What speed? At low speeds in comfort most of the times the car will start in 2nd gear while in dynamic it will start and stay in 1st gear for as long as it can. That would explain low speed difference between comfort and dynamic. At highway speeds there should be no difference, the rear only gets decoupled in economy mode as far as I know.
How flat was the road? A small grade can have significant effect. I can see my instant consumption move around during regular cruse without changing driving mode at all.OP here.

Very flat. I repeated it several times.How flat was the road? A small grade can have significant effect. I can see my instant consumption move around during regular cruse without changing driving mode at all.
Now I'm compelled to try it myselfVery flat. I repeated it several times.
It does not. Comfort and Dynamic uses identical ride height strategy throughout the entire speed range.Is it possible that changing from Comfort to Dynamic alters the suspension height which impacts efficiency?
