Mercedes CLS 450 Complete Engine – OEM Code 256.930 – Compatible with CLS 450 3.0 Hybrid

Firstly, this Mercedes CLS 450 complete engine brings a genuine, essentially new powertrain replacement to CLS 450 hybrid owners needing a full engine swap. Additionally, this listing includes an authentic 3.0-liter mild-hybrid inline-six engine carrying original code 256.930 and only 5 km of recorded use. Furthermore, buyers secure a brand-new genuine engine in one purchase instead of risking a rebuilt unit with unknown internal wear. Moreover, this engine suits independent Mercedes specialists, restoration shops, and CLS 450 owners replacing a damaged or failed engine without sourcing a full donor vehicle.

Mercedes CLS 450 Complete Engine Components Included in This Listing

• Complete 3.0-liter mild-hybrid inline-six engine block and internals
• Original turbocharger and electric auxiliary compressor assembly
• Integrated starter-generator hybrid module mounted to the block
• Factory wiring harness and engine control connector points
• Original oil cooling lines and coolant hose routing intact
• Mercedes factory identification tag confirming engine code 256.930

Why Buyers Choose This Genuine Mercedes CLS 450 Engine

Because this is an authentic OEM unit with essentially no use rather than a rebuilt or remanufactured replacement, internal tolerances, turbo matching, and hybrid module calibration match Mercedes’ original specification exactly. Meanwhile, rebuilt hybrid inline-six engines from unknown sources often carry hidden wear on turbo bearings or starter-generator components that surface after installation. As a result, this genuine near-new engine eliminates the risk of premature failure compared to units with unverified rebuild history. Similarly, the confirmed 5 km reading gives buyers essentially a brand-new engine before purchase.

Engine Characteristics and Practical Uses

• Genuine Mercedes factory inline-six engine, not a rebuilt or generic unit
• Essentially new condition confirmed at only 5 km
• Mild-hybrid configuration delivers factory-rated CLS 450 performance output
• Matches engine code 256.930 for direct compatibility without recalibration risk
• Ideal for collision repair, engine failure, or full powertrain replacement
• Sold as a complete assembly, avoiding mismatched component sourcing

Vehicle Fitment and Model Compatibility

Notably, this complete engine fits Mercedes-Benz CLS 450 models equipped with the factory 3.0-liter hybrid engine and code 256.930. Otherwise, buyers should confirm their vehicle’s original engine code matches 256.930 before ordering, since Mercedes hybrid engine calibration can vary across production runs and regional specifications. Also, engine mounting points and hybrid module coupling carry over directly onto compatible CLS chassis without additional fabrication.

Installation Notes and Engine Condition Details

Given the complexity of a hybrid inline-six engine, installation should only be performed by technicians experienced with Mercedes mild-hybrid powertrains, since starter-generator wiring and high-voltage integration require precise reconnection. Typically, engine block, turbocharger, and connectors are inspected before listing to confirm no fluid leaks or component damage. Above all, buyers should have the engine control module verified or recalibrated by a qualified Mercedes technician after installation.

Shipping Standards and Purchase Assurance

Given the weight and value of a complete engine, this unit ships on a secured pallet with reinforced crating and protective packaging around the turbocharger and wiring. Typically, buyers receive tracking confirmation promptly once the order ships. Ultimately, this engine is verified against genuine Mercedes CLS 450 specifications, giving buyers confidence in mileage and authenticity before installation begins.
