Fuel economy will improve 3-8%. Multiple articles and tests in that. It doesn't make any sense to let an engine run idle when it is at temperature when the car is at a stop.
The system has been improved over the last years. It doesn't wear your car faster the way it is designed. It is also more intuitive and less intrusive. It never bothered my inlay last cars once I got used to it.
I wouldnt call it dum and useless.
The idea behind the shutters is good. The engine should be at working temp faster when cutting cold airflow. If the shutters are prone to disfunction it is not good off course. I have had this I'm my last 4 BMW and never saw a problem. If you had a bad experience a can understand your opinion.

I am personally way more concerned about wear and tear due to the constant stopping and starting of the engine. It's going to cause more problems and reduce the life of the engine and other components. |
Apparently that is not true.
The components are made stronger and coated for less resistance.
ASS only functions when the engine is at working temperature. Wear is worse with temperature difference between the components of the engine.
I think the ICE suffers more in a PHEV than the starter liter does in a car with ASS.
