Stylistically, it leans heavily on the early Generation EQ concept of 2016. It retains the same basic shape and five-door layout of the earlier concept, albeit with altered detailing such as the front-end design. Autocar understands that the EQC achieves a drag coefficient of less than 0.30.
At 4761mm long, 1884mm wide and 1324mm tall, the EQC is 105mm longer and a considerable 315mm lower than the GLC, with which it shares its 2873mm wheelbase.
Inside, the new model uses an upgraded version of the GLC’s cabin, parts of which are set to appear on a facelifted version of the mid-range SUV due in 2019. These include a newly designed dashboard with a digital instrument and infotainment panel, reworked ventilation units and a new multi-function steering wheel featuring touch pads within the horizontal spokes.
With seating for five and 79 litres more luggage space than the GLC, at a claimed 500 litres, the EQC will count versatility as one of its strongest selling points.
The EQC is powered by a newly developed electric drivetrain that’ll be used across the EQ range. Initially previewed in the Generation EQ concept, it consists of two electric motors – one powering the front wheels and another the rears – that enable four-wheel drive capability, depending on the driving mode.
They deliver a combined 402bhp and 564lb ft to move the EQC’s 2425kg kerb weight. By comparison, the 395bhp Jaguar I-Pace weighs 2130kg.
Each of the EQC’s motors is configured differently: the front one is tuned for efficiency in the low- to mid-load range, and the rear one is described as being more performance orientated, with a greater emphasis on the mid to high- load range. Rubber subframe mounts for the motors endow the EQC with class-leading refinement, according to Mercedes-Benz.
In Sport mode, the EQC will sprint from a standstill to 62mph in 5.1sec. Top speed is limited to 112mph. In a display of the car’s versatility, Mercedes also claims a towing capacity of 1800kg and a 515kg payload.
Energy to power the motors is supplied by an 80kWh battery. All up, the lithium ion unit weighs 650kg. With a claimed range of 280 miles on the current NEDC test cycle (which is being phased out) and 249 miles on the WLTP cycle, the EQC can’t quite match the 336-mile NEDC and 292-mile WLTP claimed range of the I-Pace, which features a larger, 90kWh battery. That should translate to around 200 miles of real-world range.
A standard 7.4kW onboard charger enables AC charging via either regular mains or high-voltage public charging stations. Under DC charging, the EQC’s battery can be charged from 10% to 80% at up to 110kW in around 40min.
There are no plans to offer different battery sizes on the EQC. However Mercedes boss Dieter Zetsche said that in future, EQ models could be offered with a range of options. “Yes [we could do it] but not like in today’s vehicles with 15 variations. We will probably try to offer different price points., which would offer different mile ranges. But it is not as easy to do as an internal combustion engine equivalent.”
The EQC will be produced at Mercedes’ Bremen plant in Germany and a joint-venture factory in Beijing, China. UK examples will be made exclusively in Bremen.
Mercedes said it constructed more than 200 prototypes of the EQC in a programme claimed to have covered “several million kilometres across four continents”.
