Shortly before its market launch, the EQC is undergoing final cold weather tests in Sweden. During these further winter trials in Arjeplog, Sweden, the engineers pay particular attention to the thermal management of the battery and interior, recharging in cold conditions and handling safety, traction and recuperation on ice and snow.

After digital tests and benchtests, the 200 or so prototypes and pre-series models of the EQC cover several million kilometres on four continents. The test program includes over 500 individual tests in Europe, North America, Asia and Africa. During the course of three winters and three summers, the EQC is subjected to temperatures from minus 35° up to over plus 50° Celsius. These tests are conducted for final verification before customer deliveries of the EQC commence.

Testing is carried out in Arjeplog in Lapland, on the roads and on specially prepared test tracks. In fact testing starts earlier than this: the components are optimized in iteration cycles in Sindelfingen, and the latest variants are installed in the vehicles. The winter trials follow a strict timetable: each day begins with an early morning discussion during which the day’s activities are defined. In the evening there is a final discussion with feedback from the test team, the results for the day and planning of activities for the subsequent days and weeks. In contrast to the previous winter trials of the EQC, only the final details are optimized and verified this time. This includes fine-tuning and testing of aspects that present a particular challenge in electric vehicles.

Key facts about the EQC:

• The EQC is the first Mercedes-Benz model under the new product and technology brand EQ. At the same time the EQC is symbolic of a new era in mobility at Daimler.
• Thanks to the newly developed drive system with a compact electric powertrain (eATS) at each axle, the EQC has the driving characteristics of an all-wheel drive. The front electric motor is configured for best possible efficiency in the low to medium load range, while the rear motor provides dynamism.
• The 80 kWh (NEDC) lithium-ion battery supplies the energy and can achieve an electric operating range of over 450 km (acc. to NEDC, provisional figure) .
• Owing to its muscular proportions, the EQC is categorized as a crossover SUV. The stretched roofline and the window pattern with a low waistline and a coupé-like roof taper at the rear visually position it between an SUV and an SUV coupé.
• The assistance system ECO Assistant gives the driver comprehensive support when driving predictively: by informing him/her when the gas pedal can be released, e.g. because there is a speed limit ahead, and with functions such as gliding and specific recuperation control.
