On a unibody car, the lock pillar is also known as the?

The lock pillar on a unibody car is known as the C pillar. Understanding the context of vehicle structure is essential, particularly with unibody designs where the frame and body are integrated into a single unit. The C pillar is positioned towards the rear of the car and supports the roof structure, helping to define the space between the rear window and the rear side windows. This structural element plays a crucial role in vehicle stability and passenger safety, particularly in the event of a rollover accident.

The other designations refer to different parts of the vehicle's structure. The A pillar is located at the front of the vehicle, supporting the windshield, while the B pillar is situated between the front and rear doors, providing structural integrity for the passenger compartment. The quarter pillar typically relates to styling and reinforcement immediately adjacent to the rear segment of the vehicle but does not hold the same functional definition as the C pillar. Thus, recognizing the definitions and locations of these components is key in understanding vehicle structure and safety assessments.
