What makes you think that? Some grade school physics:

Not if "all other things are equal", like the center of mass.

They were crashed into a cement wall at THE SAME SPEED, presumably.
But if they were crashed into each other, the effective speed would be
lower for F150.

effective speed == speed relative to the center of mass of two
vehicles
