Number 1 I believe.Ok so great news guys. I just had my Expedition serviced and got on this topic with the Ford tech. He told me several things they were already "informed on the inside".
1. The 2018 Platinum will have 450 hp.
2. The 2019 Expeditions are going to offer 4 motor options. 3.5 ecoboost, 5.0 ecoboost, 6.2 Ltr na, and a diesel.
3. 2020 will bring back the Excursion on a 1 ton frame.
Take it as you will this is what he said with all sincerity.
Number 2 no way. They're making 650hp from the 3.5. Doesn't make sense to offer up 4 motor configurations when the 3.5 can be messaged to do whatever they need it to do.
Number 3 I don't believe either. For a whole host of reasons. To many to list here
But then again it's all speculation so who knows
