A short period of time has passed since the winter test of Che Di, but the heat has not decreased at all. In the much-anticipated evaluation, the new M7 has become the focus of the model, especially in the night snow backlight ACC 60KM/h static fake car test, it really showed a far leading strength. In addition, the new M7 has also been affirmed by netizens in the controversial plug-in hybrid/extended range pure electric range test. It can be said that the understanding of the car emperor winter test for the public users to popularize the advantages of dual air conditioning box double PTC over heat pump air conditioning in more detail, I have to say, this is a very successful science case. On December 22, the press conference of the car emperor also publicly emphasized: "Some cars pay attention to the heating efficiency of air conditioning, and some cars pay attention to the cruising range; ”
The new M7 can be oiled and electric, and the winter car is also worry-free
First of all, let's take a look at the hybrid/extended-range pure electric range test that understands the car emperor winter test. Before the test, under the extremely cold conditions of minus 40 degrees, the new M7 was prepared for up to 103 minutes, the doors were opened and closed 57 times, the windows were opened and closed 11 times, the air conditioner was always in a heating state, and the power was reduced from 96.3% to 50.7% before departure, and finally in the extremely cold conditions, 18.3% power was used to achieve 10.6km range, and the results were surprising.
You must know that the new M7 is equipped with dual front and rear air conditioning boxes and dual PTC, with a total power of 10kW, which can quickly heat up and meet the user's winter heating needs to extend the range, and at the same time, the waste heat brought by the range extender can be heated synchronously to the passenger compartment and battery. PTC uses resistance direct heating, which can heat quickly at -40°C or even colder, compared to heat pump air conditioners, which rely on heat exchange heating, and basically cannot heat below -20°C. The dual air conditioning unit (PTC) and the waste heat of the range extender are more efficient than heat pump air conditioners in extreme cold, but the power consumption is also correspondingly higher. However, as an extended-range model, the new M7 can be oiled and electric, without any range anxiety, so it is more humane to be equipped with PTC air conditioning.
As a range-extender car, the new M7 can be fueled and electric, with electricity and without electricity, without power, there is no range anxiety at all, and at the same time, under extremely cold conditions, it can also be warmed up by cooperating with dual air conditioning boxes (PTC) and range extenders to bring a better driving experience while ensuring the user's heating experience and battery life.
The ACC test is far ahead, and the strength of the "Chinese system" makes users exclaim
With the empowerment and blessing of Huawei, the new M7 is undoubtedly the focus of the audience in the ACC test. In the 60KM/h test of the static fake car by the snow backlight ACC at night, the perception hardware detection range of the new M7 is large, and the vehicle begins to slow down at a long distance. As the fake car gets closer and closer, the braking strength of the new M7 has also increased. Although the snow was slippery, the new M7 had a large amount of deceleration in advance, so the vehicle stopped at a distance from the fake car.
Thanks to Huawei's in-depth empowerment, the HUAWEI ADS 2.0 intelligent driving assistance system equipped with the new M7 also plays a vital role. Combined with the GOD network and the BEV network, the system can quickly receive the perception information of the hardware, and analyze the current road conditions and give the most reasonable treatment measures.
In fact, the new M7 also has a good performance in other tests, especially in the 1v1 climb test, the new M7 beat the ideal L7 with a gradient of 32%. In the low-temperature vehicle system test, the frame rate of the Hongmeng intelligent cockpit system is still maintained at 52%, ranking firmly in the front row.
Overall, the performance of the new M7 in this winter test has been recognized by the majority of netizens, fully demonstrating the product strength of the new M7 of "great wisdom and super safety". As a popular model that has exceeded 100,000 in less than 3 months on the market, the new M7 must have mastered the password of user needs, and it is believed that with the iteration of technology, the new M7 will bring users a more comfortable and convenient travel experience. Of course, we look forward to seeing a more authoritative, professional and exciting winter test in 2024.
