This is the EQC, the first Mercedes-Benz vehicle to be launched under the electric vehicle EQ brand.

Classed as a crossover SUV, the EQC features an 80kWh lithium-ion battery and all-new drive system with compact electric drivetrains at each axle.

The electric drivetrains are configured differently: the front electric motor is optimised for best possible efficiency in the low to medium load range, while the rear one determines dynamism.

Together, they generate an output of 300 kW and a maximum torque of 765 Nm. This delivers some pretty impressive performance with acceleration of 0-100km/h of 5.1 seconds and a top speed of 180km/h (governed). Range is equally impressive at more than 450km.

Power consumption and range of electric vehicles depend on the driving style so the EQC supports its driver with five driving programs, each with different characteristics: COMFORT, ECO, MAX RANGE, SPORT and an individually adaptable program. In the more economical driving modes, the haptic accelerator pedal that prompts the driver to conserve power plays an important role.

The driver is also able to influence the recuperation level using paddles behind the steering wheel.

The EQC is equipped with a water-cooled onboard charger (OBC) with a capacity of 7.4 kW, making it suitable for AC charging at home or at public charging stations.

Charging at a Mercedes-Benz Wallbox is up to three times faster than at a domestic power socket. It is faster still with DC charging.

Depending on the SoC (status of charge), the EQC can be charged with a maximum output of up to 110 kW at an appropriate charging station. In around 40 minutes, the battery can be charged from 10 – 80 percent SoC (provisional data).

The EQC features the MUBX – Mercedes-Benz User Experience – multimedia system, which has numerous EQ specific functions such as the display of range, charge status and energy flow. EQ optimised navigation, driving modes, charging current and departure time can also be controlled and set via MBUX.

The ECO Assist system gives the driver support when driving predictively: by prompting the driver when it is appropriate to come off the accelerator – for example because the vehicle is approaching a speed limit – and by functions such as coasting and specific control of recuperation. For this purpose, navigation data, traffic sign recognition and information from the intelligent safety assistants (radar and stereo camera) are linked and processed.

New services and functions of the EQC planned for market launch include Pre-entry climate control and EQ optimised navigation (that bases its calculation on the fastest route taking into account the shortest charging time).

The latest generation of Mercedes-Benz driving assistance systems are feature in the EQC. These include new functions such as predictive speed adjustment and a lane guidance system that, in a tailback on the motorway, keeps the vehicle off-centre to leave space for the emergency services.

Series production of the EQC will start in 2019 at the Mercedes-Benz plant in Bremen, Germany. D
