I am interested in the new Jeep Wrangler Unlimited 2.8CRD automatic in Sahara equipment. I have already bought various off-road magazines and obtained brochures, unfortunately I lack important information about the four-wheel drive there. That the Wrangler has “only” switchable AWD is clear, but how does it behave when driving on dry road? Does it cause tension in the drive train or can one always drive without worry in the four-wheel mode (which would surprise me)? Is the 2.8CRD a Mercedes Aggregate or VM or similar? Are there any experiences with this engine (possibly from Cherokee or others)? Other tips and experiences are always welcome!
