Yep - though in the RAM, there are two “stages” to the cylinder deactivation/ECO mode. The ECO graphic comes on - though not in deactivation mode (it simply means you are driving “economically” - Then there is a marked difference in the sound of the exhaust - was rather odd the first time I heard it! It is really obvious when the engine switches over... though it is all seamless and really - instantaneous. Punch it - and you are GONE!!!
Of course, IT’S A HEMI!
