Summary

The new 4-cylinder OM 654 diesel engine, which was introduced on the market in the spring of 2016 in combination with the NAG3 (9G-Tronic) automatic transmission, which came into the market in the fall of 2013, mark the start of a new modular powertrain with longitudinal installation at Mercedes-Benz that is fit for the future. With the model refinement of the S-Class, this first drive unit of the new Mercedes-Benz engine family is now being completed by the modular gasoline and diesel engines. In combination with the Mercedes-Benz transmission, which is also modular, the modular powertrain system is being extended from 12 V powertrains and 48 V systems all the way to high-voltage systems for plug-in powertrains and emission-free powertrains. The paper describes this modular powertrain concept from Mercedes-Benz Cars, the variants that can be derived from it, and possible potential for longitudinal powertrains that arises on the basis of the results. The powertrain concept thus constitutes the basis for enabling customer-specific, scalable technology packages and output levels on the one hand while securing the future by means of flexibility at the same time and ensuring economic efficiency of the powertrains in the face of an increased number of customer- and market-specific variants on the other hand.
