Mercedes-Benz is attracting a wide customer base with an increasing number of plug-in-hybrid models in its offer. This trend makes an important contribution on the road to CO2-neutral mobility to which Mercedes-Benz is committed as part of its decarbonisation strategy …
Plug-in hybrid vehicles offer the possibility of working only on electricity and therefore without local emissions, especially in urban areas. EQ Power models are parallel hybrids that can be charged from external power grids (plug-in). The powertrain consists of an electric drive and an internal combustion engine that work in tandem and that can drive the vehicle individually or together. Plug-in hybrids offer quick and easy entry into electric mobility – regardless of charging infrastructure. Mercedes-Benz is systematically expanding its plug-in hybrid line and by the end of the year will offer more than 20 model variants – from A-Class to S-Class, from GLA to GLE.
“Plug-in hybrids combine the best of both worlds. In the city, they work only on electricity; while at greater distances they have the advantages of the range of internal combustion engines, ”explains Dr. Torsten Eder, Chief Engineer of Mercedes-Benz Powertrains. “The vehicle as a whole is more efficient. The different characteristics of the drive complement each other. The electric motor works most efficiently when driving at low speeds, while the internal combustion engine works most efficiently at higher speeds and loads. “
Six different compact models with more than 70 kilometers of electric range
In the compact segment, Mercedes-Benz already offers a plug-in hybrid variant in all models – A-Class, A-Class Sedan, B-Class, CLA, CLA Shooting Brake and GLA. Together, the 1.33-liter four-cylinder petrol engine of 118 kW (160 hp) and the electric motor of 75 kW produce a system power of 160 kW and a total maximum torque of 450 Nm. A key feature of the electric motor, instantaneous torque, makes compact plug-in hybrids extremely flexible, as shown by performance data. For example, the A 250 e (fuel consumption combined 1.6–1.4 l / 100 km, CO2 emissions 36–32 g / km, energy consumption 15.3–14.8 kWh / 100 km) completes the classic 0 sprint up to 100 km / h in just 6.6 seconds. Even on electricity alone, it can reach a top speed of up to 140 km / h – more than enough to drive on the highway within the speed limits of most countries without the use of internal combustion engines.
The range for eclectic propulsion alone is more than 70 kilometers (NEDC). The lithium-ion battery, with a total capacity of 15.6 kWh, can be charged externally with either alternating current (AC) or direct current (DC). With a 7.4 kW (AC) Wallbox, it takes about 1 hour and 45 minutes to charge from 10 to 100% SoC (battery charge level). Using one-way fast charging with a maximum charging power of 24 kW, it takes about 25 minutes to charge the battery from 10 to 80 percent SoC. To ensure minimal restrictions in the luggage compartment compared to non-hybrid models, the exhaust system is located in the middle below the floor of the vehicle, and the rear exhaust is located in the central tunnel. Integrating the fuel tank into the axle space creates additional space under the rear bench, necessary for a high-voltage battery.
A diverse range of EQ power from medium to luxury segment with up to 100 kilometers of electric range
The EQ Power models, ranging from the C-Class to the S-Class and from the GLC to the GLE, are now third-generation hybrids. Maximum power of 90 kW and torque off-grid of 440 Nm provide enviable performance in all driving modes, including electric mode, while the top speed is 130 km / h. In the case of the GLE 350 de 4MATIC (combined fuel consumption 1.3–1.1 l / 100 km; CO₂ emissions 34–29 g / km; energy consumption 28.7–25.4 kWh / 100 km) the power is as high as 100 kW with a maximum speed of up to 160 km / h. In the new E-Class line, Mercedes-Benz offers seven different Plug-in hybrids in the sedan and station wagon versions, with petrol or diesel engine, rear-wheel drive or all-wheel drive. The electric range of the C-, E- and S-Class is about 50 kilometers (NEDC), while the GLE offers more than 100 kilometers (NEDC). Crucial to the increase in electrical range is an increased capacity of 13.5 kWh. The battery in the GLE can store as much as 31.2 kWh.
In an AC wallbox, a discharged battery can be fully charged at home in approximately 1.5 hours (GLE: 3 hours 15 minutes). Even if you use a regular home power outlet, it takes about five hours to fully charge. GLE is equipped with a COMBO charging socket with alternating or direct current. At a DC charging station, it is possible to charge the battery from 10 to 80 percent SoC in about 20 minutes and 10 to 100% SoC in 30 minutes.
Intelligent steering is at the service of the driver
To ensure that the time between charging is as long as possible and the charging time is as short as possible, the vehicle electronics system in the EQ Power models helps the driver to drive efficiently with smart charging and driving planning according to a given route. Identifies and recommends the parts of the route that are most suitable for the driving mode and take into account factors such as navigation data, topography, speed limits and traffic conditions for the entire planned route. The ECO Assist system supports the driver as a kind of trene and helps save electricity and fuel. Drivers who consistently follow his advice can reduce consumption by up to five percent compared to a normal driving profile.
Mercedes Charge simplifies the charging process
Drivers of the Mercedes-Benz EQC or plug-in hybrid model with the MBUX (Mercedes-Benz User Experience) system have optional access to one of the world’s largest charging networks with more than 300 different public charging station operators in Europe (cities, car parks, motorways, shopping malls, etc.). Convenient access to the chargers is via the Mercedes me Charge card, the Mercedes me app or via the vehicle’s own media display. There is no need for a series of different contracts – as well as direct authentication, customers benefit from the integrated payment function by simple billing after entering a single payment method. Payment is then made automatically each time the vehicle is charged. Individual charging sessions are sorted in the monthly overview. The MBUX system understands ordinary speech, which makes it easy to find charging stations near or along the selected route. All of this makes finding, charging, and paying easier than ever.
The EQ Ready application determines the individual benefits of the EQ Power model
The free EK Ready application analyzes individual user driving data and compares it with a range of parameters from electric and hybrid vehicles. It then determines whether it would make sense for the user to switch to an electric or hybrid model. The results are based on an individual usage profile, and the overall presentation is derived from an analysis of not just one individual trip, but an everyday driving profile. Self-determination is key here: personalized data is extracted only with the express prior consent of the customer.
A new version of the app is now available at the app store and can be used with any vehicle brand. The EQ Ready app not only checks if the user’s destination can also be reached by electric drive, but also provides daily information on power needs and available charging infrastructure along the route. Moreover, the user can compare his current vehicle with an alternative Mercedes-Benz engine.
