September 30, 2019 - Plug-in hybrids represent a key technology on the road to a locally emission-free future for the motor vehicle. They offer customers the benefits of two worlds: in town, they run in all-electric mode, while on long journeys they profit from the range of the combustion engine.
Plug-in hybrids make the vehicle more efficient overall, because they can firstly recover energy during braking and secondly allow the combustion engine to run in favourable operating ranges. The intelligent, route-based operating strategy takes into account e.g. navigation data, topography, speed limits and the traffic conditions for the entire planned route.
This applies to the petrol engine as well as to the diesel, which today is highly valued by many customers, especially for long distances. The Mercedes-Benz diesel plug-in hybrids of the C-, E-Class and the new GLE represent a highlight in terms of technology and efficiency. For the first time, Mercedes‑Benz has paired its state-of-the-art diesel engine with an externally chargeable hybrid system. The combination of the new OM 654 four-cylinder diesel engine with the latest-generation 9G-TRONIC 9-speed hybrid transmission promises to enhance the experience of locally emission-free mobility while at the same time offering emotively appealing driving pleasure.
The considerably longer range – with about 100 km - of the GLE 350 de 4MATIC (weighted fuel consumption 1.1 l/100 km, weighted CO2 emissions 29 g/km, weighted power consumption 25.4 kWh/100 km), which will be launched this year, points the way to an even more rewarding e-driving experience.
A special rear end design and a modified rear axle create space for the large battery. There is no step in the luggage compartment, the capacity of which is still generous at up to 1915 litres. The proportion of electric driving is not only increased by the long range, but also by rapid recharging en route. To this end the SUV has a combined charging socket for AC and DC charging. It is located in the left side wall, symmetrical with the fuel flap on the right side of the vehicle. At corresponding DC charging stations, the battery can be charged in approx. 20 minutes (10-80 percent state of charge (SoC)) or in approx. 30 minutes (10-100 percent SoC).
As the largest member of the EQ Power family, it particularly benefits from cutting-edge technology. This also includes the high potential made possible by recuperation at all four wheels, with a maximum recuperation torque of 1800 Nm. In this mode, most driving situations can be controlled merely by accelerator action. The towing capacity of up to 3500 kg is the best in this segment. Trailer Manoeuvring Assist makes manoeuvring with a trailer easy even for the inexperienced. It controls the steering angle of the towing vehicle automatically.

By the end of 2019 Mercedes-Benz will have more than ten plug-in hybrids in its range – an attractive portfolio from compact models to the flagship Mercedes-Benz S-Class. The aim is to be able to offer customers well over 20 model variants in 2020.
