Drive system Thanks to systematic electrification and intelligent downsizing, the new E-Class sets new standards in efficiency. Half of all the models will be fourth-generation plug-in hybrids. The model range already achieves this high proportion at market launch. Three of the six E-Class versions combine the advantages of a vehicle with combustion engine with those of an electric car. The combustion engines are four and six-cylinder units from the current modular Mercedes-Benz engine family FAME (Family of Modular Engines). Accordingly, the engine range plays a major role in the flexibility of the international production network, with needs-based electrification. In addition to turbocharging, both the diesel and petrol engines feature intelligent support from an integrated starter-generator (ISG). They are therefore mild hybrids. Thanks to a new battery, the power of the electric motor has been increased from 15 to 17 kW and the boost torque to 205 Nm. The ISG uses a 48 volt on-
