Rolls Royce Cullinan Black Badge Rear Bumper
For the Rolls-Royce Cullinan Black Badge, the rear bumper is a primary identifier of the Black Badge aesthetic. For the 2024–2026 Series II (facelift) models, the bumper has been further redesigned to look more integrated and aggressive compared to the Series I.
1. Key Differences: Standard vs. Black Badge
While the bumper shape is shared across the platform, the Black Badge variant is defined by its darkened trim:
-
Exhaust Finishers: Standard Cullinans have bright chrome tips. The Black Badge features mirror-black chrome exhausts, achieved through a specific electrolyte plating process only one micrometer thick.
-
Valance & Diffuser: The lower valance (the “apron”) on the Black Badge is typically finished in a high-gloss black, giving the SUV a lower, more planted visual stance.
-
Boot Trim: The horizontal trim piece above the license plate is also darkened to match the “Black Badge” theme.
2. Component Details & Part Numbers
If you are sourcing a replacement for a 2024+ Series II or an original Series I, the parts are usually ordered as a “bare” skin and then built with the specific Black Badge trim.

3. Series II (2025–2026) Specifics
The Cullinan Series II introduced in 2024 features a rear bumper with a more pronounced high-gloss black finish.

-
PDC Sensors: The Park Distance Control (PDC) sensors are now more color-matched and flush to the “monolithic” surface.
