EQ Power for the first time in the A-Class and B-Class
Plug-in hybrids are an important milestone on the road to zero-emissions driving. Mercedes‑Benz Cars is pushing ahead with the development of its plug-in hybrids under the EQ Power label. With the A 250 e, A 250 e Saloon and B 250 e models from the compact-car family with the third-generation hybrid drive are now celebrating their premiere. The A 250 e and A 250 e Saloon can be ordered now. Sale of the B 250 e starts a few weeks later. Market launch of the models will take place this year. The EQ Power for the A-Class and B-Class underscores Mercedes-Benz’s plug-in initiative: the company aims to extend its offering to more than 20 model variants by 2020.
For the new compact vehicles with EQ Power, (electric) driving pleasure and suitability for everyday use are to the fore. This is illustrated by the models highlights:
- Electric operating ranges of 70-75 km (NEDC)
- Electric output 75 kW
- System output 160 kW
- System torque 450 Nm
- Top speed 87mph (electric) 146mph (total)
- Acceleration 0-100 km/h in 6.6 seconds
- Hardly any restrictions on the load compartment.
The electric machine achieves 75 kW. Together with the 1.33-litre four-cylinder engine this adds up to a system output of 218 hp and a system torque of 450 Nm. Thanks to the EQ Power of the electric machine the A 250 e and B 250 e react immediately to a step on the accelerator, and the performance is impressive: the A 250 e, for example, requires 6.6 seconds for the sprint from 0 to 62mph.
A lithium-ion high-voltage battery with a total capacity of approx. 15.6 kWh is used as an electric energy storage unit. It can be charged at an external electric energy source. The A 250 e and B 250 e can be charged with alternating or direct current. A corresponding vehicle socket is located in the right-hand side wall of the vehicles. This means that the compact plug-in hybrids can be charged at a 7.4 kW Wallbox with alternating current (AC) within 1 h 45 min from 10-100 percent SoC (Status of Charge). For direct-current charging (DC) the battery can be charged from 10 – 80 percent SoC in around 25 minutes.
Ingenious packaging
An innovative exhaust system enables ingenious packaging: rather than extending to the end of the vehicle, the exhaust ends in a centrally positioned outlet under the vehicle floor, with the rear silencer housed in the transmission tunnel. Integrating the fuel tank into the axle installation space creates room beneath the rear seats for the high-voltage battery. This results in only minimal reduction in boot capacity for the A 250 e and B 250 e compared to the sister models without hybrid engines.
Because the compact vehicles use third-generation plug-in technology, all of their functions are also available. These include in particular the intelligent, route-based operating strategy, taking factors such as navigation data, speed regulations and route into account. The operating strategy takes into account the entire planned route and prioritises the electric driving mode for the most sensible route sections in each case.
Tailored EQ MBUX
With the launch of MBUX (Mercedes-Benz User Experience) the previous plug-in operating modes of all EQ Power models have been converted to drive programs. That means that in every Mercedes-Benz plug-in hybrid the new drive programs “Electric” and “Battery Level” are available. This is the case from the outset for the compact models. Maximum e-performance can be experienced in “Electric”. The combustion engine is only engaged if the driver uses kickdown on the accelerator pedal. In the “Electric” program the recuperation strength can also be selected via paddles behind the steering wheel. The paddles on the steering wheel enable the selection of five different recuperation levels (DAUTO, D+, D, D– and D—).
Comfort, ECO and Sport modes are also available. According to the given requirements, the driver is thus able to give priority to electric driving, place the emphasis on driving dynamics in combined drive mode or give preference to combustion mode in order to save electric range, for example.
A key comfort feature is pre-entry climate control before the vehicle is started, because the A 250 e and B 250 e have an electric refrigerant compressor. The pre-entry climate control can also be activated conveniently by smartphone. The trailer load of the compact hybrids is impressive at 1600 kg (braked).
Mercedes me Charge helps with charging en route
As well as using the domestic power supply, e.g. at a Mercedes-Benz Wallbox, convenient and uncomplicated charging is possible during the journey, too. That’s because the MBUX infotainment system (Mercedes-Benz User Experience) assists the driver in finding charging stations. The MBUX system understands natural speech, allowing the driver to start a search simply by saying “Hey Mercedes, find charging stations nearby”.
Via Mercedes me Charge, drivers of a plug-in hybrid model can optionally obtain access to one of the world’s largest charging networks, with over 300 different operators in Europe alone (municipalities, car parks, motorways, shopping centres, etc.). Thanks to navigation, Mercedes-Benz customers can find these stations easily and can gain convenient access to the charging stations via the Mercedes me Charge card, the Mercedes me App or directly from the car. No separate contracts are necessary for this: apart from simple authentication, customers benefit from an integrated payment function with simple billing after they have registered their payment method once. Each charging procedure is booked automatically. The individual charging processes are clearly listed in a monthly invoice.
