For the Third Generation Bentley Continental GT and GTC (2018–2024), part number 3SD823155 (often seen with suffix A) refers to the Engine Bonnet (Hood).

Unlike the previous generations, the 3S chassis bonnet is a highly complex aluminum panel designed with sharp “superformed” lines that are notoriously difficult to repair if dented, making complete replacements common in the salvage market.

1. Technical Specifications

• Material: Lightweight Superformed Aluminum.

• Model Code: 3S / 3SD (This will not fit the older 2003–2017 models).

• Weight: Despite its massive size, the aluminum construction keeps the panel light enough for two gas struts to operate easily.

• Safety: Features integrated mounting points for active pedestrian protection pyrotechnic actuators (hinges that pop up in an impact).

2. Part Number Variations

While 3SD823155 is the stamping number often found on the underside of the panel, the official ordering part numbers usually vary based on minor revisions:

• 3SD823031D: Often listed as the official replacement part number for the primed hood shell.

• 3SD823155A: Common identifier found on recycled or “take-off” units from 2020+ models.

3. Key Components for Installation

If you are purchasing a used or new bonnet, you will likely need to transfer or buy the following:

• Bonnet Sound Absorber (Insulation): 3SD863825 (The black felt-like pad on the underside).

• “B” Winged Emblem: 3SD853601 (Note that this differs from the Mulsanne’s retractable “Flying B”).

• Active Hinges: These are often one-time-use if the car was in a front-end collision; they must be replaced to clear dashboard airbag/pedestrian faults.
