The Hemi’s have cylinder deactivation. I was driving a brand new 300C Rental Car and the “eco” light came on when it was running on four cylinders. As I recall, it got pretty good MPG and it hauled a$$.
The C7 Corvette I’m getting has the same feature and it’s Direct Injection as well. 460 HP and 30 MPG Highway.
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!!!
