The car door panel is commonly called the interior door panel. In the UK and some regions, it's also known as the door card.
Beyond naming, the interior door panel is the decorative, upholstered panel inside the door that houses controls such as the window switches, door handle, and armrest, and provides a finished appearance while hiding the inner mechanisms. The exact terminology can vary by region and by whether the car is old or new, but the essential function remains the same: it provides access to controls and forms the interior aesthetic of the door.
