In a four-door vehicle, which pillars support the roof?

In a four-door vehicle, the roof is supported by the A, B, and C pillars, which are structurally crucial to maintaining the vehicle's integrity and providing safety for the occupants.

The A pillars are located at the front of the vehicle, holding the windshield in place and supporting the roof above the driver's and front passenger's seats. The B pillars are positioned in the middle of the vehicle, between the front and rear doors, and provide support for the roof and structural integrity, especially during a side collision. The C pillars are located at the rear of the vehicle, supporting the roof above the rear windows and contributing to the vehicle's overall stability.

This configuration of pillars enhances the vehicle's strength and safety by creating a rigid structure that can withstand various forces, ensuring that the occupants are protected in the event of a collision.
