Where is Advanced High Strength Steel located on a vehicle?

• A. Bumper only
• B. Major load bearing areas
• C. Doors only
• D. Underbody panels

Answer: (B)

Advanced High Strength Steel is used where the structure must carry crash loads and keep the occupant safety cage intact. That means it’s placed in the vehicle’s major load bearing areas—the structural elements that form the frame and pillars, rails, and other components that transfer impact forces during a crash. These areas need high strength to resist deformation and protect occupants, so AHSS is used there. Bumpers are primarily for energy absorption and protecting the car from low- to moderate-speed impacts, not for carrying the main crash loads, so they don’t rely on AHSS as much. Doors are reinforced for side impact protection, but the key load paths are the pillars and frame members, not the doors themselves. Underbody panels protect the underside and aren’t the main load-bearing structure either. So the best answer is major load bearing areas.
