The big breakthrough was the plug-in hybrid in the often so-called golf class previously denied. Next year, some manufacturers, including Volkswagen and Renault, will make a fresh start. Before that comes Mercedes, who now reveal details about their plug-in hybrid in A- and B-Class.
The powertrain consists of an electric motor with 75 kW and 300 Nm and from the A 200 (test) known 1.3-liter petrol engine with 118 kW (160 hp) and 250 Nm together. The electric motor is integrated in the dual-clutch gearbox and is integrated via a wet clutch. Stator and rotor of the electric motor are also cooled. To make room for the battery, the exhaust ends in the middle of the car. The boot should, Mercedes promises, hardly be smaller than in the conventionally powered machines. Saved Mercedes has a separate starter – the burner starts here the electric motor.
The 150-kilogram battery has a gross capacity of 15.6 kWh. Unfortunately, Daimler does not reveal how much can be used. The range in WLTP Mercedes states as follows:
- A 250 e 60 to 67 km
- A 250 e sedan 61 to 69 km
- B 250 e 56 to 67 km
On a wallbox with 7.4 kW charging should last from 10 to 100 percent 1 h 45 min, with DC Mercedes gives the charge of 10 to 80 percent with 25 minutes. Information about charging times at a 230-volt outlet makes Mercedes currently not yet.
The fuel consumption in the no longer valid NEDC is 1.4 to 1.6 liters, the power consumption is given in this cycle with 14.7 to 15.4 kWh. Why Mercedes does not specify all values in the WLTP is understandable in view of the higher values from the point of view of the manufacturer – but it is not user-friendly. Especially since the NEDC is actually since the emission standard Euro 6c, which is mandatory since September 2018 for all first-time registered cars, history. Like the competition, Mercedes uses the inertia of legislators and obfuscates the current cycle values.
Since the switch to the new WLTP cycle, recalculation of fuel consumption without prior battery charging has become even more complicated. In the NEDC, the underlying formula was relatively easy to change. In the WLTP not only the consumption values of plug-in hybrids are even harder to understand – above all, they are no longer comparable with each other.
