### **I. C-Class Retrofit: From W205 to W206 Aesthetics**
*(Applicable to 2015–2021 W205 models)*
1. Front-End Revolution**
- Headlight Conversion: Replace halogen/LED units with W206-style multibeam LED headlights featuring three-point DRL signatures. Requires custom wiring harnesses and SAM module reprogramming.
-Grille & Bumper: Install AMG Line Panamericana grille (compatible with W205 hood) paired with a 2023-style front bumper incorporating larger air intakes and aerodynamic splitter.
- Hood Modification: Optional raised power dome hood for aggressive W206 proportions (requires structural reinforcement).
2. Rear Modernization
- Taillight Upgrade: Retrofit horizontal two-piece LED taillights with animated turn signals using OEM-style housings from brands like Vland.
- Diffuser Integration: Add W206-inspired rear diffuser with integrated quad exhaust cutouts, compatible with existing exhaust layouts.
3. Cockpit Digitalization
- MBUX Conversion: Replace COMAND system with 10.25-inch MBUX dual-screen setup (requires CAN bus emulator and HVAC control relocation).
- Steering Wheel Swap: Install 2023 AMG steering wheel with capacitive touch controls and revised paddle shifters.
- Ambient Lighting: Retrofit 64-color LED ambient lighting with turbine-style air vents.

II. E-Class Transformation: Bridging W213 to W214
(Targeting 2017–2023 W213 models)
1. Exterior Reincarnation
- Digital Light Integration: Upgrade to W214’s projector-free DIGITAL LIGHT system with 2.3 million pixel resolution (requires custom firmware and front sensor calibration).
- Body Line Optimization: Install flared wheel arches and concealed door handles for streamlined W214 proportions.
- Trunklid Reshaping: Modify trunklid to accommodate new star-pattern LED taillights with 3D holographic effects.
2. Hybrid-Ready Powertrain Updates
- Mild-Hybrid Retrofit: Add 48V BSG (Belt-Starter Generator) system to M264 engines using OEM parts from newer E300 models.
- Transmission Reflash: Reprogram 9G-Tronic transmission for W214’s smoother shift logic and ECO Glide functionality.
3. Chassis Enhancements
- Rear-Axle Steering: Retrofit optional 10-degree rear-wheel steering system (requires subframe modification).
- Adaptive Suspension Update: Install W214’s AIRMATIC air suspension with road-scan preview function using dual-camera input.

III. S-Class Grand Evolution: W222 to W223 Conversion
(For 2014–2020 W222 models)
1. Flagship Styling Overhaul
- Vertical Grille Conversion: Replace horizontal grille with W223’s vertical-slat design (custom radiator support required).
- 3D Taillight Transplant: Install W223’s tri-sphere OLED taillights with laser-etched star motifs (modified trunk structure).
- Door Handle Revolution: Retrofit flush-mounted electric door handles with proximity sensors.
2. Autonomous Driving Tech
- DRIVE PILOT Retrofit: Integrate L3 autonomous hardware including LiDAR roof module and upgraded radar array.
- 3D Instrument Cluster: Replace analog gauges with W223’s 12.8-inch OLED 3D dash display (requires ZGW gateway replacement).
3. Executive Interior Upgrades
- MBUX Hyperscreen Installation: Custom-fit 56-inch curved glass panel housing three OLED displays (modified dashboard framework).
- Energizing Comfort Control: Add fragrance system, advanced seat kinetics, and 4D Burmester audio synchronization.
---IV. Technical Considerations**
1. Compatibility: Laser scanning for precise body panel alignment during widebody conversions.
2. Lighting Certification: Ensure all LED/OLED upgrades comply with regional photometric regulations.
3. OEM+ Electronics: Use STAR Diagnostic systems for module coding to prevent system conflicts.
4. Value Preservation: Maintain original VIN-critical components to avoid depreciation penalties.
