ORIGINAL Lamborghini Urus S PERFORMANTE CARBON BONNET

the Original Lamborghini Urus Performante Carbon Fiber Bonnet (Hood) remains the ultimate upgrade for the Urus platform. While it comes standard on the Performante, it is a highly sought-after retrofit for the Urus S and the base models due to its aggressive air vents and significant weight reduction.

1. Official Part Identification

There are two primary versions of the original factory bonnet, depending on the desired finish:

• Part Number: 4ML823031 (Base prefix)

• Visible Carbon Fiber Version: This version features a high-gloss clear coat intended to show the carbon weave. It often has a specific suffix (like G or H) to denote the exposed finish.

• Paintable Version: Made of the same carbon fiber but intended to be painted in the vehicle’s body color.

• The Vents: The “Performante” look is defined by the two deep, functional longitudinal air extractors.

2. 2026 Market Pricing (Genuine Original)

Prices for genuine Lamborghini carbon fiber are exceptionally high because they are produced using autoclave technology to ensure structural integrity at high speeds ($300\text{ km/h}+$).

3. Compatibility: Retrofitting to Urus S

• Direct Bolt-On: The bonnet is a 100% direct mechanical fit for the Urus S and the original Urus (2018–2022).

• Hardware: It uses the same hinges and primary latch, but it is recommended to use the Performante-specific gas struts (hood shocks) because the carbon hood is significantly lighter than the standard aluminum hood; standard struts may be too “stiff” and pop the lighter hood up too aggressively.

• Airflow: The vents are functional and assist in lowering the under-hood temperature of the $4.0\text{L}$ Twin-Turbo V8.

4. How to Verify an “Original” Bonnet

In 2026, the market is saturated with high-quality replicas (e.g., from Mansory, Novitec, or unbranded factories). To ensure yours is Original Lamborghini:

• The Underside: Original hoods have a specific “raw” carbon finish on the underside with a molded-in Lamborghini Part Number and “Made in Italy” stamp.

• The Weave: Factory Lamborghini carbon uses a specific $2\times2$ twill weave that is perfectly symmetrical. Replicas often show “distortions” or “pulls” in the weave around the vent curves.

• Weight: An original carbon bonnet weighs roughly $10\text{–}12\text{ kg}$ ($22\text{–}26\text{ lbs}$), which is nearly $50\%$ lighter than the $20\text{ kg}+$ aluminum standard hood.

5. Maintenance Note

• UV Protection: Even original carbon can “yellow” or “cloud” over several years of high heat. In 2026, it is standard practice to apply a Paint Protection Film (PPF) and a Ceramic Coating immediately after installation to protect the resin from the sun and engine heat.
