Hey everyone, new here. I am test driving a 2006 Commander over the weekend. It is an 06 limited with the 5.7. I was wondering if all the 5.7 Hemi engines are multi displacement. This one doesnt have a manual with it and I have seen 2 different things online. One website said it was an option on the 5.7 one said all 5.7s had it. Also is the 4x4 sytem with the 5.7 a true full time, or does it automatically turn off and on??? I appreciate any help you can give me.
