Re: what I want to KNOW ... Dear FLincMoCo
I just don't see Ford green-lighting a LincStang, despite the S550 existing for only one model (sorta ignores the One Ford/economy-of-scale/platform-sharing ethos).
I don't see why a RWD platform for a Lincoln/Ford SUV is such a crazy idea. Of course, if you accept that Ford is not in the habit of developing platforms in general (see Jaguar, Mazda & Volvo & Ford of Europe), perhaps it is crazy. Doesn't the current Explorer/Navigator sit on a RWD truck chassis? Newer SUVs are designed more like unibody crossovers than body-on-frame vehicles so I think it can be done. If that platform is scalable, it can also be the base for large RWD sedans.
This makes me wonder what the D6 is really going to be. Ford hasn't shown much ground-breaking creativity in platform development in the past. If the D6 is strictly another FWD-based platform only, I would be very disappointed. The D6 is probably the last (first?) chance to show the world that it has first-class engineering chops (I'm not doubting the engineers here; I'm doubting management).
