What is the emblem on the Audi fender?

Vehicle body panels often have stamped numbers. If it's a stamped number, it's usually the part number - each automotive component has a unique part number. If the number consists of 17 digits, then it's the vehicle identification number (VIN). Additional information: Audi: Audi is a renowned automobile developer and manufacturer, with its logo featuring four interlinked rings. Currently a subsidiary of Volkswagen Group, its headquarters is located in Ingolstadt, Germany. Main models include Audi A1, A3, A4, A5, A6, A7, A8, Q1, Q2, Q3, Q5, Q7, Q8, TT, R8, as well as the S and RS performance series.

As an enthusiast who frequently studies automotive design, I particularly enjoy observing such details. That small square badge on the Audi fender is actually a visual code for Audi's performance hierarchy—the one with "quattro" lettering represents the all-wheel-drive system, while the S-line emblem serves as the identity medal for the sport package version. It first appeared on the 1980 quattro rally car, and now even the electric e-tron models continue this design tradition. More conspicuous in placement than BMW's M badge, yet more minimalist than Mercedes' AMG emblem. A tip when car shopping: run your fingers along the badge edges—OEM parts have precise chamfering, while aftermarket ones often feel rough. This detail also serves as a trick to distinguish imported models from domestic versions, as some locally produced variants may omit the side badges.

Having touched over a hundred Audi fender badges at 4S dealerships, I discovered three hidden secrets in this emblem. The diamond-shaped metal base is actually hollow, featuring a specially designed aerodynamic airflow structure. The gap between the badge and body panel is strictly controlled within 0.5mm - even high-pressure car wash jets can't dislodge it. The most easily overlooked detail is the vibration-damping rubber pad on the reverse side, which prevents rattling noises. I've witnessed cases where owners of older A6L models installed illuminated side badges, only to have their BCM modules burn out. My personal recommendation is to maintain the factory original condition, as this represents a critical wind noise control point that Audi engineers repeatedly tested.

During a visit to the Audi factory in Germany years ago, I discovered that the fender emblem undergoes three special processes. First, laser etching is applied to the stainless steel base plate, followed by the injection of dual-color resin, and finally vacuum chrome plating. The most time-consuming part is the waterproof test—each emblem must endure thermal cycles from -30° to 80°C, simulating five years of exposure to extreme sun and rain. Now, the emblem on the 2023 new A8 also features a self-cleaning nano-coating, making it less prone to mud accumulation during rainy drives. Interestingly, this spot was once home to the Audi four-ring logo, which was later replaced with the current exclusive emblem for better recognition of performance models.
