Mercedes M254 engines with capacities of 1.5 and 2.0 liters were introduced for the first time in 2020 and are characterized by plasma-sprayed iron with a Nanoslide coating and an integrated starter-generator (ISG). Currently, these power units are only installed in the fifth generation of the popular C-Class model. R4 series: M166, M260, M264, M266, M270, M271, M274, and M282.

The weight of the M254 engine according to the catalog is 135 kg. The engine number M254 is located at the junction of the block and the gearbox. This turbocharged engine has just appeared and naturally there is no statistics of its breakdowns. All units of the modular series are afraid of detonation, so do not use gasoline below AI-98. As before, the weak point of the design of this series of engines is considered to be the Camtronic system. Here, direct fuel injection and valves will surely quickly become clogged with carbon deposits. This is exactly the type of engine that was planned to be installed in the new E-Class, but for some reason they refused.
