This is from allpar, not new but just read it today and thought I'd share:
Chrysler announced on June 21, 2007: “For 2009, Chrysler Group [sic] will deliver a significantly upgraded version of its renowned 5.7-liter HEMI V-8, resulting in notable gains in fuel efficiency, refinement, power and torque.” They also announced that the Phoenix V6 would get MDS. The gains are expected to come via variable cam timing, according to always-accurate oh20.
Redriderbob had correctly predicted in May 2007: Chrysler will be debut a revamped Multi Displacement System (MDS) on most of its V6 and V8 lineup by the year 2010. They have been working on a new updated MDS system that will debut on the 2009 Dodge Ram 1500 models. After its debut, it will be featured on the full V8 lineup (except SRT). Most of the V6 engines in Chrysler’s arsenal will also feature MDS.
oh20 also said we can expect three 5.7 Hemis in 2009; the variable-cam edition should be around 380 hp. At the same time, a 6.4 liter Hemi is expected to get nearly 500 hp (we have heard a range from 450-480). He also said that the 6.1 Hemi (SRT version) might get MDS in 2009 or 2010.
