# MASERATI QUATTROPORTE – COMPLETE PROTECTION & ADAS GUIDE
The Maserati Quattroporte is more than just a luxury sedan; it is the original Italian four-door sports car. As a CBU (Completely Built Unit) import, it requires a protection strategy that respects its advanced sensor suite and unique engineering. At **Protint**, we provide bespoke, ADAS-aware solutions to preserve this masterpiece.
> **⚠️ Critical Sensor Advisory**: The Quattroporte is equipped with an extensive Level 2 ADAS suite, including **Highway Assist, Lane Keeping Assist, Active Blind Spot Assist, and Rear Cross Path** . These systems rely on a **front camera behind the windscreen**, a **front radar in the grille**, and **BSA/RPC radar sensors in the rear bumper corners** . **DO NOT TINT THE FRONT WINDSHIELD**—this will blind the camera and disable these safety features.

## ⚖️ 1. SUN FILM LEGALITY – What Quattroporte Owners Must Know (2026)
The legal position regarding sun films is nuanced. While the Supreme Court has banned aftermarket films , there is a parliamentary push to amend the law to permit them with VLT restrictions . However, **as of 2026, no amendment has been passed** .
### The Supreme Court's Ruling
The Hon’ble Supreme Court in 2012 held that affixation of solar films is illegal, being a violation of CMVRs . The Court ruled that the manufacturer may tint the glass, but **no black film or any other material can be affixed on the wind screen or side glasses of the vehicle** .
### Legal Requirements (Rule 100(2) of CMVR, 1989)
| Window | Minimum VLT Required |
| :--- | :--- |
| **Front & Rear Windscreen** | **70%** |
| **Side Windows** | **50%** |
### Your Legal Sun Protection Options
| Solution | Legality | Use Case | Recommendation |
| :--- | :--- | :--- | :--- |
| **Factory Maserati Glass** | ✅ 100% Legal | Driving | As equipped – DO NOT remove |
| **Magnetic/Clip-on Sun Shades** | ✅ 100% Legal (Parked Only) | Parked UV protection | **HIGHLY RECOMMENDED** – remove while driving |
| **Aftermarket Tinted Films** | ❌ Illegal | Not permitted | **NOT RECOMMENDED** – Challan risk + ADAS interference |
**Enforcement**: Police actively enforce the ban using tint meters and can issue challans on the spot .

## 2. ⚠️⚠️⚠️ CRITICAL: QUATTROPORTE ADAS SENSOR SUITE
The Quattroporte (2017+) is packed with advanced driver assistance systems that rely on a network of sensors . **These sensors must remain unobstructed** for your safety systems to function correctly .
### The Quattroporte ADAS Features & Sensor Map
| Feature | Function | Sensors Used | Protection Rule |
| :--- | :--- | :--- | :--- |
| **Highway Assist (HAS)** | Semi-autonomous driving up to 145 km/h | Front camera + front radar + EPS | **🚫 NO FILM ON WINDSHIELD** |
| **Lane Keeping Assist (LKA)** | Corrective steering torque to keep in lane | Front camera + front radar | **🚫 NO FILM ON WINDSHIELD** |
| **Active Blind Spot Assist (ABSA)** | Monitors blind spots; applies steering torque | **BSA/RPC sensors** in rear bumper corners | **✂️ Precision cutouts required** |
| **Rear Cross Path (RCP)** | Alerts when reversing with approaching vehicles | **BSA/RPC sensors** in rear bumper corners | **✂️ Precision cutouts required** |
| **Forward Collision Warning (FCW Plus)** | Alerts of potential front collisions | Front radar + front camera | **✂️ Precision cutout required** |
| **Surround View Camera** | 360° view for parking | 4 cameras (front grille, side mirrors, rear) | **🚫 NO PPF ON LENSES** |
| **Rear View Camera** | Reversing guidance | Rear camera | **🚫 NO PPF ON LENS** |
### BSA/RPC Sensor Location – CRITICAL
The Quattroporte uses **radar-based sensors located inside the rear bumper** for the Active Blind Spot Assist and Rear Cross Path systems . The part number for this sensor is **670101840** .
**⚠️ If you have PPF applied to the rear bumper, the installer must make precision cutouts for these BSA/RPC sensors. DO NOT COVER them.**
### ⚠️ CRITICAL INSTALLATION RULES
1. **DO NOT TINT THE FRONT WINDSHIELD**: The camera and radar behind the windscreen power Highway Assist, Lane Keeping Assist, and Traffic Sign Recognition . Tinting will disable these features.
2. **PRECISION CUTOUT FOR FRONT RADAR**: When applying PPF to the front bumper, the installer must make a precision cutout for the radar sensor .
3. **PRECISION CUTOUTS FOR BSA/RPC SENSORS**: The rear bumper has BSA/RPC radar sensors . PPF must have precision cutouts here.
4. **NO PPF ON CAMERA LENSES**: The Surround View Camera system uses multiple lenses . All must remain unobstructed.
5. **USE NON-METALLIC FILMS**: Metallic films can interfere with radar signals.
**If Your Quattroporte Has Been in an Accident**: Sensors may become misaligned. Have an authorised Maserati dealer verify sensor alignment.

## 🛡️ 3. HYPER-LUXURY PAINT PROTECTION (PPF)
A full-body PPF for a luxury sedan like the Quattroporte is a significant investment. The cost is justified by the value of the vehicle and the cost of repainting. An experienced installer is crucial, as the Quattroporte's complex body panels demand precision.
### PPF Cost Context (2026)
PPF prices vary based on vehicle size, film quality, and installer. For a full-size luxury sedan like the Quattroporte:
| Coverage Type | Estimated Price Range (₹) | Best For |
| :--- | :--- | :--- |
| **Full Body PPF (SUV/Luxury Sedan)** | ₹1, 20, 000 – ₹2, 00, 000+ | Ultimate preservation; maximum protection |
| **Full Front PPF (Bumper, Full Bonnet)** | ₹25, 000 – ₹50, 000 | Most owners – stops 80% of stone chips |
### High-Impact PPF Coverage Areas
| Priority | Area | Why It Matters | Sensor Consideration |
| :--- | :--- | :--- | :--- |
| **CRITICAL** | **Front Camera Area** | Behind windshield – powers ADAS | **🚫 NO FILM ON WINDSHIELD** |
| **CRITICAL** | **Front Radar Area** | Behind front grille – powers ADAS | **✂️ Precision cutout required** |
| **CRITICAL** | **BSA/RPC Sensors** | Inside rear bumper corners | **✂️ Precision cutouts required** |
| **Highest** | Full front bumper | Stone chip ground zero | Contains front radar + sensors |
| **High** | Full bonnet / hood | Long, sculpted surface vulnerable to chips | No sensors |
| **High** | Door edges & door cups | Daily use wear | No sensors |
| **High** | Side mirrors | Contain surround view cameras | **🚫 NO PPF ON LENSES** |
| **Medium** | Rear bumper area | Contains BSA/RPC sensors + camera | **✂️ Precision cutouts for all** |
| **Optional** | Full vehicle | Maximum protection | All sensors precision-cut |
### 🧪 Ceramic Coating
Ceramic coating is applied over the paint (or over the PPF) to lock in the gloss and add a hydrophobic layer. A professional-grade ceramic coating provides long-lasting protection, enhanced gloss, and excellent water beading properties.
### Ceramic Coating Benefits
- **Hydrophobic Effect**: Water, mud, and road grime bead up and slide off – easier cleaning
- **UV Protection**: Blocks up to 99% of UV rays, preventing paint fading
- **Chemical Resistance**: Protects against bird droppings, tree sap, and acid rain
- **Enhanced Gloss**: Adds deep, mirror-like shine
- **Durability**: Professional coating lasts 3-7 years

## 🎯 PRO TIP FOR QUATTROPORTE OWNERS
**The 'Dealer to Detailer' Delivery**
The best time to protect your Quattroporte is *before* it hits the road. Arrange for delivery directly to our studio.
**Your Delivery Day Checklist**:
1. **Dealer Wash**: Instruct the dealership **NOT** to wash the car before delivery.
2. **Sensor Awareness**: Know your Quattroporte's sensors: front camera behind windshield, front radar behind grille, and BSA/RPC sensors in rear bumper corners . Ensure any PPF installer makes precision cutouts here.
3. **Immediate PPF**: Book Full Front PPF before the car hits the road. The Quattroporte's prominent grille is a magnet for stone chips.
4. **Legal Sun Protection**: Buy a set of **magnetic sun shades** for parked use. **DO NOT install aftermarket tint**.
5. **Ceramic Coating**: Apply a premium coating over the PPF to lock in the gloss.
6. **Documentation**: Keep records of PPF and coating for resale value.
