The New EQB: Family-Size Electric Mobility

Whether it’s for a large nuclear family or a small extended family: as a seven-seater, the new EQB offers space for many family configurations and a wide variety of transport needs. This gives it an exceptional position among compact electric cars. The two seats in the third row can be used by people up to 1.65 meters tall, and child seats can also be fitted there. The new EQB will launch in Europe and China at the end of the year, followed by the US market launch in 2022. After the EQA, it is already the second all-electric compact car from Mercedes-EQ. The powerful and efficient electric drive, clever recuperation, and predictive Navigation with Electric Intelligence are just some of the features that link it to the EQA.

The electric initiative from Mercedes-Benz Cars is accelerating as fast as the Mercedes-EQ models themselves: with the EQA, EQB, the electric business saloon EQE and the luxury saloon EQS, a total of four new models from Mercedes-EQ are being introduced in 2021, plus the Concept EQT as a harbinger of a new high level of quality in the small van segment. The Mercedes-Benz plug-in hybrid family, currently consisting of more than 20 model variants, is being renewed with electrified derivatives of the C-Class and the S-Class. For 2021, Mercedes-Benz Cars expects to increase the xEV share, i.e. of plug-in hybrids and fully electric vehicles, to around 13 percent. In addition, mild hybrids with a starter-generator and 48-volt system are conquering the product range, especially of the Group’s luxury vehicles.

“With the new EQB, we have designed an iconic electric SUV which incorporates the square forms of our off-roaders and projects them into the future. Its significant silhouette is combined with futuristic elements such as the black panel front to create the extraordinary look of this vehicle”, says Gorden Wagener, Chief Design Officer of the Daimler Group.

In Europe, the all-electric compact SUV will be launched as the EQB 300 4MATIC (combined electrical consumption NEDC: 16.2 kWh/100 km; combined CO₂ emissions: 0 g/km)^[1] with 168 kW and as the EQB 350 4MATIC with 215 kW (combined electrical consumption NEDC: 16.2 kWh/100 km; combined CO₂ emissions: 0 g/km)1. The ranges according to WLTP are 419 kilometers in each case. Further variants to meet specific customer requirements will follow, including a particularly long-range version.

Generous space and variable, level boot

The EQB enriches the successful Mercedes compact car family and is closely related to two models in particular: to the EQA, whose advanced drive technology it shares, and to the GLB compact SUV. This is where the long-wheelbase (2829 millimeters), the spacious and variable interior, and the optional third row of seats with two additional individual seats come from.

The dimensions of the five-seater: 4684/1834/1667 millimetres (length/width^[2]/height). Space is generous. The headroom in the first row of seats is 1035 millimeters, in the second it is 979 millimeters for the five-seater. At 87 millimeters, the knee space in the rear of the five-seater reaches a comfortable level. The boot is level and spacious: the load volume of 495 to 1710 or 465 to 1620 liters (figures for five- and seven-seaters respectively) has the qualities of a Mid-range station wagon. The backrests of the seats in the second row can be adjusted in several stages as standard, and this row features fore/aft adjustment of 140 millimeters as an option. This enables the boot to be enlarged by up to 190 liters and put to versatile use.

As an option, the EQB has a third row of seats comprising two extra individual seats. The seats offer people up to a height of 1.65 meters a comfortable amount of space. Extensive safety features include retractable head restraints, seat belts with belt tensioners and force limiters on all outer seats, and a side window bag that also covers passengers in the third row. A total of up to four child seats can be fitted in rows two and three, plus one more in the front passenger seat. To increase luggage space, the third-row seats can be lowered flush into the load floor.

Electro design aesthetics brimming with character

The EQB interprets Mercedes–EQ’s Progressive Luxury in an edgy and particularly characterful way. It features the characteristic Mercedes-EQ black panel grille with a central star. A further distinctive design feature of the all-electric world of Mercedes-EQ vehicles is the continuous light strip at the front and rear. A horizontal fiber-optic strip connects the daytime running lights of the full-LED headlamps, ensuring a high level of recognisability both in daylight and at night. The inside of the headlamps is finished to a high level of quality, detail, and precision. Blue color highlights within the headlamp reinforce the signature Mercedes-EQ appearance.

The function-oriented greenhouse with an upright windscreen makes the comfortable interior possible. Circumferential and protective cladding elements structure the overall proportion. The muscular and sensuously modeled vehicle shoulder dominates the side view, which is further enhanced by the rise of the beltline. Outwardly positioned wheels give the EQB a powerful character and confident stance on the road. Exclusive to this model are light-alloy wheels in a bi- or tri-color design, up to 20 inches in size, in some cases with rosé gold-colored or blue decorative trim.

The LED taillights merge seamlessly into the tapering LED light strip. This underlines the horizontal sense of width of the EQB in the rearview. In addition, the number plate is placed on the bumper, which allows for a beautifully sculpted tailgate. The studded roof rails underline the high utility value of the new EQB.

The large body of the dashboard has a cut-out in the driver and passenger area. The driver faces a Widescreen Cockpit, with control and display via MBUX (Mercedes-Benz User Experience). The robust character of the interior is underlined by tubular elements in an aluminum look. They sit as handles in the doors, in the center console, and in the instrument panel on the passenger side.

Depending on the design and equipment line, a spectacular backlit trim piece and rosé gold-colored decorative elements on the air vents, seats, and vehicle key provide clues to the electric character in the interior of the EQB. The instruments, with their electric car-specific displays, pick up on the same color scheme with rosé gold-colored and blue highlights.

The EQB achieves a very good Cd value from 0.28. The frontal area A totals 2.53 m². Among the most important aerodynamic measures are the completely closed cooling air control system in the upper section, the aerodynamically efficient front and rear aprons, a very smooth, almost completely enclosed underbody, specially optimized Aero wheels, and specifically adapted front and rear wheel spoilers.

Efficient driving pleasure and Navigation with Electric Intelligence

ECO Assist offers a recuperation process optimized for a particular situation. It incorporates navigation data, traffic sign recognition, and information from the vehicle sensors into its efficiency strategy. Anticipatory driving saves power, thereby extending the range.

The standard Navigation with Electric Intelligence also contributes to the effortless handling of the EQB in everyday life. This calculates the fastest route to the given destination. On the basis of continual range simulations, the system makes allowance for any necessary charging stops as well as for numerous other factors, such as the topography and the weather. It is also able to react dynamically to changes, for instance in the traffic situation or personal driving style. In addition, the Navigation with Electric Intelligence ensures that the high-voltage battery is brought to an optimal charging temperature before a planned charging stop if required.

Sophisticated charging technology, large network, and compensation through green electricity

At home or at public charging stations, the EQB can be conveniently charged at up to 11 kW with alternating current (AC) using the onboard charger. The charging time required for a full charge depends on the available infrastructure and the country-specific vehicle equipment. Charging at a Mercedes-Benz Wallbox is considerably faster than at a domestic power socket.

And it is of course even faster at direct current (DC) fast-charging stations. Depending on the SoC (State of Charge) and the temperature of the high-voltage battery, the EQB charges at a corresponding charging station with a maximum power of up to 100 kW. The charging time is then just over 30 minutes from 10-80 percent SoC. And after just 15 minutes, electricity is recharged for up to another 150 kilometers (WLTP)^[3]. For AC and DC charging, the EQB is equipped as standard in Europe and the USA with a CCS (Combined Charging Systems) connector in the right-hand side panel.

Via Mercedes me Charge, EQB drivers will be able to use one of the most extensive charging networks in the world: this currently comprises more than 600,000 AC and DC charging stations across 31 countries. Mercedes me Charge allows Mercedes-EQ customers convenient use of the charging stations of various providers, while they also benefit from an integrated payment function with simple billing processes. With the EQB, one year of Mercedes me Charge is included.

In Europe, Mercedes-Benz guarantees by means of high-quality certificates of origin that electricity from renewable energies is fed into the grid for charging volumes that flow via Mercedes me Charge. With Mercedes me Charge, customers can charge at more than 250,000 public charging stations across Europe, where Mercedes-Benz ensures subsequent compensation through green electricity.

Cooperative support for the driver and a high level of crash safety

The EQB features intelligent driving assistance systems with cooperative support for the driver. Active Lane Keeping Assist and Active Brake Assist are fitted as standard. In many critical situations, the latter has the ability to prevent a collision or reduce its severity with autonomous braking. The system is also able to brake for stationary vehicles and crossing pedestrians at typical city speeds. The enhanced functions of the Driving Assistance Package include, for example, the turning manoeuvre function, the emergency corridor function, the exit warning function alerting the driver to approaching cyclists or vehicles, and a warning when pedestrians are detected near zebra crossings.

The EQB is also a true Mercedes when it comes to passive safety. Building on the robust bodyshell structure of the GLB, the body of the EQB was adapted to the special requirements of an electric car. The battery sits within a frame made out of extruded sections. This takes on a structural function which until now was maintained by the cross members in the underfloor. A battery guard in the front area of the battery is able to prevent the energy storage unit from being pierced by foreign objects.

Of course, the EQB had to pass the brand’s usual extensive crash test program. Stringent requirements for the battery and all components carrying electrical current also apply.

The EQB in the global production network

Production of the EQB will start in October 2021 at two locations within the Mercedes-Benz Cars global production network: at the Hungarian Mercedes-Benz plant in Kecskemét for the global market and at the German-Chinese joint venture BBAC in Beijing for the local market. Preparations, including staff qualification processes and reconstruction work, have already commenced at the plants. The EQB compact SUV will be the first all-electric production vehicle from Hungary and will complement the plug-in hybrid portfolio produced there.

Since it commenced production in 2012, the Hungarian Mercedes-Benz plant has continually increased in importance within the global production network of Mercedes-Benz Cars. In addition to digital networking, the strengths of the compact car production network include direct exchange with the lead plant for compact cars in Rastatt, Baden-Württemberg.
