I think expanding the cd6 platform to include a new Nautilus based on the Mustang cuv could work. Replacing the Aviator, though, would be a major mistake imo. 

I like the new grill treatment, but it being in Piano black gives me concerns about durability to holding up against bugs and rocks long term and still looking good. 

I wouldn't hold my breath on that one.    The current Explorer is supposed to stay in production till 2032 I want to say, so we are still 6-7 years out and who knows what is going to change between now and then. If a significantly updated Explorer was supposed to come out in 2030 or so, I'd say a Mustang CUV might be possible, but IMO I don't think it is. If anything I can see another Ford badged C2 Utility with the Nautilus coming about instead, esp if it winds up in Mexico   

I don't mind it. The grill is a bit large but overall it's still a pretty vehicle. A shame not much has changed with the interior (minus themes and colors). A bigger central screen would've been great. Still nice though. 

Here's another option.  With cd6 spawning a mustang CUV - move Nautilus to that platform and build it in Chicago.  Maybe even replace Aviator.

I really like it but I maybe the BL model shouldn't have the black pieces around the grille. It looks more premium without it  

Correct.  That's what I'm thinking will happen.   Mach-E goes away. Make it a C2 plant - move Nautilus and Corsair there.  Add Bronco Sport (whether primary or overflow) to give additional volume for the plant.   Simultaneously, continue with the plan to add a "Corsair EV" (placeholder name) on CE1 at LAP to start that customer transition Add Bronco sibling   That allows Lincoln to maintain and add to the lineup:   Corsair "Corsair EV" Nautilus Bronco sibling Aviator Navigator / L

You are probably right, but I guess the need to find a solution then because as you say I also don't think that the Lincoln Bronco would appeal to the Nautilus buyers, and it is the best selling model and with a 65% rate of customers coming from another brand, you cannot loose it 

Yeah, our biggest local department, Fort Lauderdale, uses a lot of Tahoes.

They could still move Nautius and Corsair to Cuautitlan.  It would be a mistake to walk away from those 2 in favor of EVs.
