The tests were carried out in the Chinese region of Inner Mongolia, which is famous for severe frosts. It was attended by 40 electric cars and plug-in hybrids at once. They were fully charged and left outside overnight in a frost of -20 degrees.

Then, in the morning, electric cars set off on a trip along the same route in the city and on the highway. Each car had a driver and a passenger in the cabin, and the climate control was set to +24 degrees.

The average power reserve loss was 40-60%. Oddly enough, Chinese electric cars turned out to be the most long-range in cold weather.
