Important factors for the lifecycle assessment of a plug-in hybrid vehicle include the resources consumed in production and the charging processes of the high voltage battery during vehicle operation. In production, the additional drivetrain components of the new Mercedes-Benz C-Class C 300 e plug-in hybrid sedan require a greater use of material and energy resources.
However, an overall picture only emerges when the entire life cycle is considered: This is because during its operating phase, the C 300 e benefits from the high efficiency of the electrified powertrain.
Data, facts and figures: The lifecycle performance of the C 300e plug-in hybrid at a glance
Mercedes-Benz based its analysis of the charging of the high-voltage battery on two different energy sources: One scenario is based on power from renewable sources (electricity from hydropower), and the other on the European power mix2. Both scenarios are based on a mileage of 200,000 km. The result: If renewable power (hydroelectric power) is used to charge the C 300 e, lifecycle CO2 emissions can be almost halved.
With the increased electric range (WLTP) brought about by the C 300 e battery and its usable energy capacity of approximately 25 kWh and an electric output of 95 kW, the car can cover distances of up to 116 km in all-electric mode without using the combustion engine.
210 components with a total weight of 90.4 kg can be made in part with materials that result in lower consumption of resources (recycled plastics and renewable raw materials).
Mercedes-Benz is building a battery recycling plant in Kuppenheim in southern Germany with a process that will achieve a recovery rate of over 96%. All company-owned Mercedes-Benz car and van plants worldwide have operated on a net carbon-neutral basis since 2022.
Since 2021, Mercedes-Benz has ensured a subsequent offset with green electricity when customers use Mercedes me Charge public charging stations in Europe, the USA and Canada. Certificates of origin ensure that corresponding amounts of green electricity are fed into the grid for charged energy quantities after the charging process.
