Auto Start Stop.

Recommended Posts

I have found from the day I took delivery of my 2.0 Nautilus that the auto start stop often seems to be somewhat jarring. Last week when I was in Arizona on vacation for two weeks I had a 19 Equinox with a 2.0 liter engine and start stop, the transition was almost seamless. Trying to get a sense of if my car is representative of Ford stop start, or if I have an issue to be addressed.   Thx

I've heard the 2.0L is rougher than the larger engines.   The 3.5LeB in my F150 is super smooth.   Only way to really tell is to test drive another one at the dealership and compare.

The smoothness of a 4 cylinder stop-start engine re-start may depend on whether the engine is always programmed to shut down & restart with one of the 4 cylinders at/near TDC (top dead center) charged with compressed fuel, i.e. ready to fire off instantly when the re-start ignition is initiated. Perhaps the Equinox and Nautilus engines are programmed differently re: stop-start sequencing. Also, the more the engine cylinders, e.g. 4 cylinder vs 6 cylinder, the smoother the re-start of a 6 cylinder due to better inherent engine balance features...6 cyl engines are inherently better balanced.
