The 5.7L "Magnum" has a multi-displacement engine. At cruising speed, it
shuts off four cylinders to save fuel (and it does - 23-25mpg) - once you
step on the pedal, it turns them back on and you can't feel them coming on
either - but the power it definitely there. Very nice system and is
controlled via the PCM, Solenoids under the intake (for the lifters/valves),
and injectors are turned off (on for a few rotations and then back off
again).
Yeah, I totally agree with you on the 5.7L not fitting in a Dakota - makes
no sense.

Subject: DML: HEMI engine ?
Went to Dodge premier night tonight, and got my silver
eagle.
Also got an earfull of a sales pitch that the 4.7l hemi
has " variable displacement " and if you are cruiseing
level, not demanding much, some cyls shut down and save
fuel?
is that true, and if so, does the instrument cluster
display that ?
Oh , and the 5.7 hemi is too big to fit in a DAK ,
but fits ok in the sports car....
