Mercedes is also launching the new W 206 C-Class generation as a plug-in hybrid. This allows the diesel and gasoline engine to drive 100 kilometers on pure electric power. Here you can find out everything you need to know about the PHEVs.
You’ve probably read dozens of times that a plug-in hybrid can drive up to 50 kilometers on electric power. With the PHEV models of the new C-Class (W 206), Mercedes wants to double this range figure. To achieve this, the Stuttgart-based company is garnishing its mid-range model with a 95 kW (129 hp) electric motor and a 25.4 kWh battery.
Neither the C 300 e nor the C 300 de will have a specially designed combustion engine. The new four-cylinder M 254 (gasoline) and OM 654 M (diesel) engines will be used, both with a displacement of two liters and 204 hp (gasoline) and 200 hp (diesel) respectively. The gasoline hybrid is to be available in a further power stage at a later date. All engines can be configured with all-wheel drive and as station wagon versions on request.
The hybrid version of the C-Class is available on a diesel or gasoline basis, as an estate and sedan, and with rear- or all-wheel drive.
Mercedes describes the design of the hybrid powertrain as compact. To live up to this claim, the manufacturer integrates the power electronics and stator into the transmission housing, thereby reducing the required installation space. At the same time, increasing the system voltage is said to improve drive performance without requiring larger cable cross sections. The permanently excited internal-rotor synchronous machine provides support in driving mode with a maximum of 440 Newton meters and takes over in solo mode up to a maximum speed of 140.
Mercedes does not purchase the high-voltage battery, but produces it in-house. It consists of 96 pouch cells and has internal cooling. This allows the operating temperature to be adjusted more precisely without fear of performance losses in hot or cold weather. In addition, thermal management enables fast charging via direct current at up to 55 kW. At this charging power, the PHEV C-Class needs around 30 minutes for a full charge. Three-phase charging at the home AC wallbox is ensured by the standard 11 kW on-board charger. Together with the battery, however, this costs cargo space in the rear compartment.
