The quarter panel is the section of a car's body that surrounds the rear wheel well. On most sedans, coupes, and hatchbacks, it's the panel between the rear door and the trunk lid (or hatch), extending from the base of the C-pillar (the rear roof support) down to the bumper and around the wheel arch. On vehicles without a rear door, like two-door coupes, the quarter panel starts immediately behind the front door. The front section surrounding the front wheel is typically called the fender, not the quarter panel.
Understanding its location is crucial because the quarter panel is often a costly repair. Unlike a fender, which can be unbolted, the rear quarter panel is usually welded directly to the car's unibody structure. This makes replacement a complex and labor-intensive process involving cutting and welding. Damage here, even from a minor sideswipe, can quickly escalate into a major insurance claim.
For identification, look at the side of your car. The quarter panel is the large, stamped metal section that encompasses the rear wheel. It's a critical part of the vehicle's structural integrity and aesthetic lines. Because it's integral, repairs often require specialized body shop equipment to ensure the vehicle's safety and alignment are preserved.
| Characteristic | Front Section (Fender) | Rear Section (Quarter Panel) |
|---|---|---|
| Location | Surrounds the front wheel | Surrounds the rear wheel |
| Typical Attachment | Often bolted on for easy replacement | Usually welded to the unibody structure |
| Repair Complexity | Generally lower cost and faster | Higher cost, more labor-intensive |
| Common on | All vehicle types | Sedans, Coupes, Hatchbacks, SUVs |
