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

Abstract

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.
