Which pillar extends up sides of windshield from the main body to the roof and provides mounting posts for the windshield, cowl, and front corners of the roof?

• A. C-Pillar
• B. D-Pillar
• C. A/Hinge Pillar
• D. B/Center Pillar

Answer: (C)

The pillar described is the A-pillar, also known as the hinge pillar. It sits at the outer edge of the windshield and extends from the main body up to the roof, forming the frame around the windshield. It provides the mounting posts for the windshield, the cowl, and the front corners of the roof, helping to transfer loads from the roof into the body and contributing to overall crash safety. The hinge pillar gets its name from the door hinges often mounting to it, and it’s the frontmost pillar you see at the sides of the windshield.
