Thanks to CTOnews.com netizens for the delivery of clues about the past. CTOnews.com news on December 11, after the world questioned the understanding of the car emperor winter test results, Great Wall Motor also joined the "war situation" and announced that a communication meeting on understanding the car emperor winter test standards would be held at 15:00 on December 14.

The official poster of Great Wall Automobile shows that there will be several major topics for this communication meeting, including:

1. The scientific and fair standard of winter test of new energy.

2. Vehicle preparation standard for pure electric range test

3. Vehicle electricity standard for climbing angle test

4. Vehicle braking standard for climbing distance test

It is worth mentioning that Yu Chengdong also expressed his position on the test results of M7 participating in the "2023 car King Winter Test" on Wechat moments: deceiving people and misleading the public! Science and rigor are the basic rules that should be followed!

Understand the car emperor official said yesterday: the test standards are completely unified, all models are treated equally!

CTOnews.com has previously reported in detail the controversial results of the "winter test" of the M7 model, and the timeline is roughly as follows:

Understanding car Emperor recently conducted winter performance tests on dozens of new energy vehicles, involving the performance of pure electric vehicles and hybrid vehicles in many areas. The test site is located in Mohe and is currently in extremely cold weather. In the plug-in hybrid group's "pure electric life success rate" project, the boundary M7 only achieved a success rate of 31.6%. (the Mengshi 917, the Deep Blue S7 extended range version and the Chuanqi E9 PHEV cannot drive in pure electric mode in the extremely cold environment of-30 ℃, excluding the results.)

On Friday, AITO explained the test in detail: the test media confirmed that the vehicle was heated by air conditioning for a total of 71 minutes before the formal test, and continued for another 40 minutes after the temperature in the car reached 24 degrees Celsius.

In this process, there are more than ten times to open and close the doors and windows, of which the longest time is more than 3 minutes, which greatly increases the energy consumption of air conditioning and leads to a rapid decline in electricity consumption. Under the condition of severe cold and continuous heating of air conditioning, the windows and doors are opened for many times for a long time, which seriously deviates from the real use scene of users.

In addition, the remaining power of the vehicle during the test was 74.9%, and the test began only when the driver and four 60-kilogram sandbags were carried. When the power was 20.4%, the range extender started, and the actual battery power consumption was 54.5%. To achieve a pure electric range of 55.3 km in extreme weather conditions in winter.
