WOW!! Super technical question.  That's a toughy.
 
I searched and could not find any specific information indicating that the 3 has boron steel used in it's substructure.  However, articles that I did find indicate that there are likely varying percentages of boron steel (BS?? ) in many modern cars, Volvo being among them.  In fact one article from 2004 stated, "Volvo probably uses boron steel the most." and also that, "For now, boron steel is found primarily on European vehicles." The S40 and V50 had door reinforcement beams made of the stuff beginning in 2004 & 2005 respectively.
 
May I ask, are you having your car fixed after being t-boned or side-swiped?
