Just a little something I noticed...
Hey everyone,
I just noticed that in most Mercedes-Benz's, when you let go of the accelerator, the car seems to engine brake slightly, and the car slows down. However, in all other cars I've driven/been in, if you let go of the accelerator, the car seems to just coast and the speed will follow the slope of the road. I find this more interesting than a nuisance.
Can someone explain to me what causes this and how the whole setup works? Thanks!

Means the transmission doesn't go to "neutral" when power isn't being applied.
Plus, of course, fuel injection shuts completely off when doing this, so there is plenty of engine braking.
Old cars with carburetors continued to deliver fuel on the overrun.

Thanks for your reply,
I've noticed that even modern Fords and Chevys and the like go into neutral when you let off on the accelerator. Do brands like BMW and Audi feature the same setup as MB, so that the transmission does NOT go into neutral when you let go of the accelerator, causing the car to engine brake?
Thanks!
