Original Mercedes C190 GTR GT R Front Bumper AMG Panamericana
The “Green Hell Magno” Aesthetic | Panamericana Grille | Active Aerodynamics
The AMG GT R (C190) front bumper is one of the most aggressive and functional designs in Mercedes-Benz history. Unlike the standard GT or GT S, the GT R bumper is significantly wider, more aerodynamic, and houses the sophisticated AIRPANEL active air management system.
Whether you are performing a conversion or a factory repair, this bumper defines the “Predator” look of the AMG flagship. Original Mercedes C190 GTR GT R Front Bumper AMG Panamericana
1. Key Design Features
-
Panamericana Grille: The signature vertical-slat grille inspired by the 1952 300 SL racer. This bumper is molded specifically to hold the large-format version of this grille.
-
Wider Profile: The GT R bumper is wider than the standard AMG GT to accommodate the flared carbon fiber fenders and wider front track.
-
Jet-Wing Design: The lower “A-wing” and large outer cooling ducts are optimized to feed air to the additional wheel-arch radiators.
-
Carbon Fiber Accents: Most GT R bumpers feature a front splitter and air-intake “flick” inserts finished in high-gloss carbon fiber.
2. Technical Components & Aerodynamics
The GT R bumper is more than just a plastic shell; it is an aerodynamic tool:
| Component | Function |
| AIRPANEL (Code 20U) | Vertical louvers behind the grille that open/close in ~1 second to reduce drag or increase cooling. |
| Active Underbody | A carbon fiber element in the underbody that moves downward by 40mm at speeds over 80km/h in RACE mode to create a Venturi effect. |
| Brake Cooling Ducts | Integrated channels that direct high-pressure air directly onto the 390mm/402mm front rotors. |
3. Part Number Guidance
Because of the various sensor and camera options, the primary bumper skin part number varies. However, a common core part number for the GT R skin is:
A1908851400 (Base Skin – Primed)
Required Assembly Parts:
-
Grille: A1908880300 (Panamericana)
-
Lower Splitter: A1908851301 (Standard) or A1908851401 (Carbon Fiber)
-
Outer Grilles: Left (A1908851500) / Right (A1908851600)
4. Retrofit Warning: GT to GT R Conversion
If you are planning to install a GT R bumper on a standard AMG GT / GT S, please note the following challenges:
-
Width Mismatch: The GT R bumper is designed for wider fenders. If you use standard fenders, the bumper will “poke out” at the wheel arches by several centimeters. You must replace the front fenders with GT R versions.
-
Active Aero Sensors: Standard GT models lack the software/wiring for the AIRPANEL louvers. You will need to mount the louvers in a “permanently open” position or use an emulator to prevent dash errors.
-
Parking Sensors: If your car has Parktronic (Code 235), ensure the new bumper has the correct pre-drilled holes, as the GT R often comes without front sensors in track-focused configurations.
5. Why Choose Genuine OEM?
At speeds of 318 km/h (198 mph), the front bumper is under immense pressure. Aftermarket “GT R style” bumpers are often made of fiberglass or thin ABS which can deform or shatter at high speeds. Genuine Mercedes-AMG bumpers are wind-tunnel tested and made of reinforced polypropylene to ensure the downforce generated by the splitter doesn’t rip the bumper off the mounts.
