I don't know precisely what Chrysler's abbreviation for their variable cam phasing system is, but all '09 and newer 5.7 HEMIs have it, period. The automatic-equipped cars also get MDS (part-time 4 cylinder mode), a worthy attempt to compensate somewhat for the mileage penalty you pay for a conventional automatic vs a 6-speed manual. The '09 and newer MDS is programmed more aggressively (it activates more often than it used to), so you'll see it activate at lower speeds and at greater throttle openings than was previously the case. Hope this helps...
