Endurance tests around the globe
Shortly before its market launch, the EQC (combined power consumption: 22.2 kWh/100 km; combined CO2 emissions: 0 g/km, provisional figures)[1] is undergoing final tests in Sweden's snowy landscapes. 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.
Winter trials
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.

*provisional figures
[1] Figures for power consumption and CO2 emissions are provisional, and were measured by the Technical Service. The figures for operating range are likewise provisional. No EC type approval and certificate of conformity with official figures is available as yet. Differences between the stated figures and the official figures are possible.
