I moved from a Nissan Altima Hybrid to the X3 and it is very noticable in the X3. In the Altima for the most part I never noticed the engine going on or off, with the X3 I sometimes notice the engine going off and almost always notice it turning back on. For now I plan to use it and find it works well with Auto Hold.
