DS mode vs Eco Pro/Comfort/Sport/Sport+
I've seen a couple of posts on this but none that have satisfactorily explained the differences.
So... what's the difference between putting the car in DS mode (shifter to the left) and putting it in Sport mode (button pushed up for sport). And what happens if you drive in both modes at the same time? Is there any further benefit or difference?
You can also shift into DS mode WHILE in any of the drive modes (EcoPro, Comfort, Sport, Sport+) What does DS mode in each of these modes?
