I know Ford invested heavily in Rivian, specifically in their "skateboard" EV architecture and was going to build a model using that tech, but is this it?
Seems too early, but it does seem cool and possible.
I don't think the Mustang Mach-E is using a Rivian platform due to the face that it's smaller than their R1T and R1S, but maybe Ford is using their software. I do remember reading that Rivian is Helping Ford with a new EV but it could be for a different SUV/Truck.
