Where is the rear panel located on a car?

The rear panel of a sedan is the rear barrier of the trunk. Below is relevant knowledge about the rear panel: Composition of the rear panel: The rear panel is composed of several pieces combined together, not a single unit. Vehicle depreciation loss refers to the loss formed when a vehicle is damaged in a traffic accident and, although its performance is restored after repair, its service life, safety performance, handling performance, etc., are difficult to return to their previous state, inevitably reducing its actual value—that is, the loss caused by the accident leading to a decrease in the vehicle's value. Precautions: Deformation of the rear panel has very little effect on the car; aspects like the vehicle's handling performance are basically unaffected. If the rear panel is damaged, it should be repaired with sheet metal as much as possible, and cutting should be avoided to the greatest extent. Once cut, the vehicle is considered an accident car.
The rear panel is actually the steel plate at the very back of the trunk! When you lift the trunk mat, the metal plate closest to the rear end of the car is it. This component connects the rear bumper reinforcement and the left and right rear longitudinal beams, acting like a solid wall protecting the trunk. In sedans, it stands behind the spare tire well; in SUV hatchbacks, it sits right next to the tailgate frame. Some cars have holes in the rear panel for mounting rear parking sensor probes. During a rear-end collision, this panel deforms to absorb energy, preventing items in the trunk from being thrown into the cabin. You usually don't see it, but if it's missing, the trunk capacity becomes noticeably smaller.
My friend always mentions this panel when repairing cars. It's located in the area between the rear wheels and the trunk, the vertical section at the frontmost part of the rear frame. It's the rearmost metal wall you touch when opening the trunk. This area hides several critical welding points connecting the floor rails and side rails. In terms of body repair, the design considers front and rear crumple zones—the rear panel serves as the second line of defense against impacts (the bumper being the first buffer), deforming only under severe collisions. In cases where a truck rear-ends a sedan, the bending of the rear panel creates space to protect the passenger compartment structure.
You mean that metal panel under the trunk mat? The rear wall right behind the latch position! Many cars have double-layer stamped rear panels with rust-proof wax sandwiched in between, and some even have sound insulation foam attached. If the car gets rear-ended, repair shops need to check its deformation level - if it exceeds the safety threshold, it needs replacement. Once when I helped a colleague inspect a used car, I could tell it was in an accident just by looking at the rear panel weld spots from inside the trunk - factory welds should be fish-scale pattern, while repair shops usually do projection welding.
The rear panel is the most expensive part to repair after a rear-end collision because it's located at the very end of the vehicle's frame structure, essentially serving as the inner back wall of the trunk. It plays a crucial role in connecting the rear bumper frame to the vehicle's body frame, requiring high-strength steel for manufacturing. In some MPVs, the rear panel even extends to the lower part of the chassis to protect the fuel tank from being damaged by road debris. Lightweight vehicle models may have weight-reduction holes in the rear panel, but structural strength must be maintained. Be cautious not to use high-pressure water jets directly on the weld seams during car washes, as this can easily wash away the rust-proof wax.
