Reliability score : 7.8/10

The Mercedes-Benz S-Class (W223 generation) represents the pinnacle of luxury and technology within the brand with the star. Launched at the end of 2020, it is based on the MRA2 platform and marks a major technological breakthrough with the introduction of the MBUX 2.0 system, an augmented reality head-up display, and an almost entirely tactile interface. While the demand for this sheet focuses on gasoline engines, it is crucial to note that all pure combustion versions (S 450, S 500, S 580) are now equipped with 48V mild hybridization (EQ Boost) with an integrated starter-generator (ISG).

🎯 Verdict

The Mercedes S-Class W223 is a masterpiece of comfort and technology, but it pays the price for its avant-gardism with temperamental electronic reliability, especially on 2020-2022 models. Mechanically, the gasoline engines (S 450 and S 500 with the L6 M256) are excellent choices: they offer driving pleasure worthy of the badge while controlling their consumption thanks to 48V hybridization. The purchase of a recent used W223 must imperatively be accompanied by an extended manufacturer warranty (such as Mercedes-Benz Certified) to protect against the exorbitant costs associated with failures of ECUs, screens, or the air suspension. Avoid the very first production models.
