The BMW i7 in drive testing under extreme conditions - tests in hot climates

The series development process for the BMW i7 is entering its final phase with a demanding test program under extreme road and weather conditions. During so-called hot-land testing on test tracks and public roads around the world, the development engineers primarily verify the performance and reliability of the electric motors, all-wheel drive and high-voltage battery under maximum stress from high temperatures, unpaved roads, dust generation and large differences in altitude. The road to production readiness will take the BMW i7 prototypes over gravel tracks and into desert areas, into the mountains and on selected highly dynamic routes, among other things. The BMW i7, the world's only purely electrically powered luxury sedan, will be presented in the course of 2022 together with other model variants of the new BMW 7 Series. The endurance test in the heat regions of various countries and continents serves in particular to test and safeguard all components of the electric drive system. In continuous use at extremely high outside temperatures, permanent sunlight and dry conditions, the components of the fifth-generation BMW eDrive technology developed for the BMW i7 demonstrate their unrestricted functionality even under the most adverse conditions.
