“Something seemed odd so I rolled down my window to listen...it was this damn feature stopping the other vehicles DIESEL engine (it was a MBz). I thought how ridiculosis it is to start-stop a diesel engine with glow-plugs an a 22:1 compression ratio.”
Agree, insane. You can idle a diesel all day and burn something like one gallon of fuel.
Plus the alternator has an increased load on the engine because it has to top off the battery again because of the juice used to start it. So the on/off system isn’t actually saving much of anything at all in the long run.
My wife’s mercedes has this feature, she likes it, but it comes with a switch that can disable the feature, which I do.
