| 2021 (Facelift) | Introduction of the M256 inline-6 engine with mild hybrid technology, significant interior and exterior styling updates, advanced MBUX infotainment system. | New engine and electrical system could present unforeseen issues, potential for increased repair costs compared to older models. |
| 2022 | Refinement of the M256 inline-6 engine, improved MBUX performance, updated driver assistance systems. | Continued potential for electrical gremlins associated with the new engine and hybrid system, ongoing supply chain issues. |
| 2023 | Minor updates and refinements, continued reliance on the M256 inline-6, expanded customization options. | Potential for continued supply chain issues, long-term reliability of the mild hybrid system still unknown. |
| 2024 | Latest model year with incremental improvements, available with updated technology and safety features. | Potential for higher initial cost, long-term reliability still to be fully determined. |
Detailed Explanations
2019: As the inaugural year for the E450, the 2019 model offers a blend of performance and luxury. It features the smooth and responsive M276 3.0L V6 biturbo engine, producing 362 horsepower, paired with a 9-speed automatic transmission. Styling updates from the E-Class refresh are present, and standard safety features provide peace of mind. However, being a first-year model, it might have minor quirks ironed out in subsequent years. The COMAND infotainment system, while functional, is less advanced than the MBUX system found in later models.
2020: The 2020 E450 benefits from continued refinement of the M276 engine and features improved driver assistance technologies. Mercedes-Benz addressed some initial production concerns from the 2019 model year, leading to potentially enhanced reliability. Expanded options packages allowed buyers to further customize their vehicles. However, the infotainment system remains the older COMAND interface, and potential for carry-over issues from the previous year still exists.
2021 (Pre-Facelift): The final year for the M276 V6 engine. The 2021 pre-facelift model represents the peak refinement of this engine in the E450. It was available in a variety of body styles, including sedan, coupe, cabriolet, and wagon. While the engine is proven and reliable, the infotainment system is nearing the end of its life cycle, and potential supply chain issues may affect availability.
2021 (Facelift): A pivotal year, the 2021 facelifted E450 introduces the M256 3.0L inline-6 engine with mild hybrid technology, replacing the V6. This engine boasts improved efficiency and performance, generating 362 horsepower (plus an additional 21 hp from the electric assist). Significant interior and exterior styling updates modernize the car, and the advanced MBUX infotainment system provides a more intuitive and connected experience. However, being a completely new engine and electrical system, potential unforeseen issues could arise, and repair costs might be higher compared to older models.
2022: The 2022 E450 builds upon the foundation laid by the 2021 facelift, further refining the M256 inline-6 engine and improving MBUX performance. Updated driver assistance systems enhance safety and convenience. While the M256 engine is becoming more established, the potential for electrical gremlins associated with the new engine and hybrid system remains a consideration. Ongoing supply chain issues might also affect parts availability and repair times.
2023: The 2023 E450 features minor updates and refinements, continuing to rely on the M256 inline-6 engine. Expanded customization options allow buyers to personalize their vehicles to a greater extent. While the engine is becoming increasingly reliable, the long-term reliability of the mild hybrid system is still being assessed. Potential for continued supply chain issues remains a factor.
2024: As the latest model year, the 2024 E450 boasts incremental improvements and potentially updated technology and safety features. However, being the newest model, its long-term reliability is yet to be fully determined, and the initial cost will likely be higher.
Frequently Asked Questions
Which E450 model year offers the best balance of reliability and features? The 2021 facelifted model offers a great balance, with the new M256 engine and MBUX system, though it's newer so potential issues are less well-known than earlier models.
Are there any specific problems to look out for in the 2019 E450? Some early 2019 models experienced minor electrical glitches and infotainment system quirks, but these were often addressed under warranty.
Is the M256 inline-6 engine more reliable than the M276 V6? The M276 V6 is a well-established engine with a proven track record. The M256 is newer and incorporates a mild hybrid system, so long-term reliability is still being assessed, but it's generally considered a robust engine.
