Rolling resistance (not tires)
Hope this is the right forum to post this question. If not, mods please move. Also I searched but couldn't find any answers.
This is my first Mercedes-Benz (2012 C250) - although my family has had several Benz cars in the past. What I've noticed is that all of Mercedes require a deliberate push of the accelerator to get rolling. Similarly they don't coast much without needing the accelerator unless I'm going down a pretty steep incline.
But most other automatic transmission cars I've driven start rolling right upon brake lift-off. And even a gentle grade can be coasted down without using the accelerator at all.
What is it about M-B cars that need more accelerator usage? I'm not talking about tire resistance - as this happens even with properly inflated tires. Would they be more efficient if they rolled more easily on their own? Or would that require a higher idle or something else that would make it less efficient?
