The Ford Police Interceptor SUV has a larger ballistic panel inside the doors to stop common rounds that police would come in contact with. The panel provides NIJ level III ballistic protection.

Randy Freiburger, a Police Special Vehicle Engineer for Ford Motor Company, talks about the Interceptor’s bullet proof doors.

The doors were tested against an array of calibers.

9mm

.45 acp

5.56 M855 and M193

7.62×39 and .308

I am curious how much weight those ballistic panels add to the vehicle?

Update Note: I got a new email today about this and Ford says these doors will stop armour piercing rounds.
