Does anyone know if the 3.5 Eco in the 2017 Explorer is a 1st gen or 2nd gen engine?

The 2017 still has the first gen stuff. When they release the 2018 aluminum bodied Expy later this year it will have the 2nd gen 3.5 with 10 speed.

Interestingly, there are very very little differences other than valve train, fueling and other obvious things. The bottom end is extremely similar.
