You have probably read dozens of times that a plug-in hybrid can drive up to 50 kilometers electrically. With the PHEV models of the new C-Class (W 206), Mercedes wants to double this range. The Stuttgart-based company has garnished its mid-range model with a 95 kW (129 PS) electric motor and a 25.4 kWh battery.
Neither the C 300 e nor the C 300 de have a specially designed combustion engine. The new four-cylinder M 254 (petrol) and OM 654 M (diesel), both with two-liter displacement and 204 hp (petrol) and 200 hp (diesel), are used. The gasoline hybrids will later be available in a further performance level. All engines can be configured with all-wheel drive and as a combi version on request.
Mercedes describes the construction of the hybrid drive train as compact. In order to meet this claim, the manufacturer has integrated power electronics and stator into the gearbox housing, thereby reducing the installation space required. At the same time, an increase in the system voltage should improve the drive performance without requiring larger cable cross-sections. The permanently excited internal rotor synchronous machine provides support when driving with a maximum of 440 Newton meters and takes over a maximum of 140 km / h in solo operation.
Mercedes does not buy 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 loss of performance in hot or cold weather. In addition, the thermal management enables quick charging with direct current with up to 55 kW. With this charging capacity, the PHEV-C-Class needs around 30 minutes for a full charge. The standard 11 kW onboard charger ensures three-phase charging at the home AC wallbox. Together with the battery, however, this costs space in the rear compartment.
Less cargo space than in the combustion engine
While a T-model as a combustion engine takes 490 liters, the space available in the PHEV is reduced to 360 liters. That in turn is 45 liters more than the plug-in hybrid of the previous generation. The length of the load compartment floor increases by 63 millimeters to 1.04 meters and the height increases to 732 millimeters. With the seats folded down, you can stow up to 1,375 liters (1,510 liters in the combustion engine). Normally 455 liters fit under the hatchback of the sedan, with the part-time electrician it is 140 less with 315 liters. What benefits the loading comfort, however, is the elimination of a step. A level loading floor awaits the luggage in the hybrid rear, and the rear axle of the PHEV models is air-sprung and level-adjustable as standard.
The recuperation power can be set in the driving modes Electric, Hybrid and Battery Hold using the shift paddles from D + to D to D- (One Pedal Drive). Mercedes specifies the maximum recuperation power at 100 kW. If necessary, the system automatically selects the driving mode and recuperation level, taking into account navigation data, topography, traffic and speed limit. This works with active route guidance.
All other innovations in the W 206 series, such as the second generation MBUX, the Digital Light, the rear-axle steering or over-the-air updates, are of course also available in hybrid versions. You can find more details about the new C-Class HERE.
Yes, they are just part of it.
No, they are no longer up to date.
Mercedes no longer offers the C-Class of the W 206 series as a pure combustion engine. All drive variants are designed as at least mild hybrids. With the large configuration range of plug-in hybrid models, the Stuttgart-based company is underlining its claim to reduce emissions. This also fits in with the elimination of six- and eight-cylinder models.
