Yes it does. Chrysler and Ford are more "stealthful" about the situation than GM AFM and GM DOD. On my GM I could watch the dash display and see V8-V4-V8-V4 going on back and forth adnuseaum. I guess not likely on any Chrysler or Ford product because of the nasty reputation of cylinder deactivation in general and the law suits.
