That's the Procon TEN system, it's designed to make sure the seatbelts 
are tight AND yank the steering wheel into the dash in a HARD frontal 
impact.  The tranny tunnel is also armored to help push the engine and 
transmission under the car. I've seen three cars come through the yard 
that I get parts at that all have been hit so hard the bumper was at the 
shock tower yet the interior was fine except for the steering wheel in 
the through the dash.......
