What is the term used to refer to the inside of a car door?

The term that refers to the inside of a car door is the door panel. This component covers the interior part of the door, providing both functionality and aesthetics. It typically includes features such as the armrest, the speaker mounts, and controls for windows and locks. The door panel serves as a protective barrier and contributes to the overall comfort and design of the vehicle's interior.

In comparison to other terms, the door frame refers to the structural elements that support the door but do not constitute the interior surface. The door shell refers to the outer structure of the door, which houses the window and the locking mechanisms. The door skin is the outermost layer of the door that is visible from the outside, serving primarily as a protective layer and exterior finish. Each of these terms describes different components or layers associated with a car door, but the door panel specifically denotes the interior portion that occupants typically interact with.
