Mercedes GLC 300 and 4MATIC, the third generation plug-in hybrid

Mercedes continues its electrification of its range, which will come to have ten plug-in hybrid models by the end of 2019, presenting the new Mercedes GLC 300  and 4MATIC , which also brings the third generation of Stuttgart’s hybrid powertrain to its debut in Frankfurt , in this specific case in a plug-in hybrid configuration.

The 2-liter turbo petrol engine with 211 hp and 350 Nm of torque is supported by an electric unit of 90 kW and 400 Nm. Together they configure a system power of 320 hp and a torque of 700 Nm, enough to accelerate from 0 to 100 km / h in 5.7 seconds – thanks also to all-wheel drive – and exceed 230 km / h. In full electric mode, on the other hand, it reaches 130 km / h and the range is around 40 km – WLTP approval is still in progress – thanks to a 13.5 kWh battery. At the level of consumption and emissions we are at 2.5-2.2 l / 100 km and 57-51 g / km of CO2, obviously measured with the plus of the full battery.

A little bit of mechanics

The heart of this powetrain is an electric motor inserted inside the 9G-Tronic gearbox and is designed as an internal rotor, according to the principle of the permanent excitation synchronous machine. Compared to the previous version, one of the major innovations consists in the adoption of a torque converter with exclusion clutch , as a starting element, and an additional separation clutch between the combustion engine and the electric unit, for driving in exclusively electric mode .

The stator of the electric unit is integrated in the casing of the transmission head; the rotor, in the kinematic chain composed of separation clutch and gearbox input. The cooling of the stator and rotor according to need allows to easily exploit the peak and continuous power of the electric unit.
