Der neue Vierzylinder-Dieselmotor OM 640 für die Mercedes-Benz A-Klasse

Fur die A-Klasse der zweiten Generation bestand die Aufgabe, einen Dieselmotor in drei Leistungsstufen mit verbesserten Komforteigenschaften in schrag liegender Einbauform zu entwickeln. Mit dem neuen Common-Rail-Motor OM 640 bietet Mercedes-Benz nun eine attraktive Motorisierung an, die Komfort, Agilitat und Fahrleistung mit guten Verbrauchswerten vereinigt.

The new four-cylinder OM 640 diesel engine for the Mercedes-Benz A-class

The second-generation A-Class presented the task of developing a diesel engine in three power versions with improved comfort properties and an inclined installation position. With the new OM 640 common rail engine, Mercedes-Benz now offers an attractive engine that combines comfort, agility and performance with impressive fuel consumption figures.

PLUG-IN Hybrid from Mercedes-Benz – The next generation PLUG-IN Hybrid with 4-cylinder gasoline engine

The modularly structured hybrid system from Mercedes-Benz has been available in combination with gasoline and diesel engines since 2012. Previous experiences in the hybrid series production development have shown that although batteries of higher capacity enhance the electric driving experience, there are no further benefits in terms of efficiency and package. For this reason, Mercedes-Benz made a decision on the combination of increased electrical capacity with the option of external recharging. To this end, the S500 plug-in hybrid was initially launched in 2014. For the first time a variant with 4-cylinder gasoline engine has subsequently emanated from the modular hybrid system. In combination with an electrical range of 31 km, this downsizing allows previously unknown certification of 48 g CO2/km in this class. Furthermore, agility values on the 6-cylinder level could be implemented with very direct driving characteristics due to the increased capacity of the battery, the selected powertrain topology and the direct response of the electrical machine.
