Getting detailed information out of Ford has not been to successful to date. I am still working on it and hope to have color coded body structure diagrams soon. The first information on the 2010 Ford Taurus post on this is site was short. New information is now available.
The Ford Taurus has dual-phase steel in the vehicle structure, including the inner A-pillar reinforcements, outer B-pillar reinforcements, roof rail and outer A-pillar assembly. The Volvo XC60 integrates safety into the body structure by utilizing ultra high-strength steels (1500 MPa) in the A-posts, B-posts, and floor sill reinforcements.
Just look at that UHSS strength number, 1500 Mpa. Now look at the chart below. That is almost the strong UHSS used today. Good luck out there! Just remember to have a Plan A,B,C etc!
