: Previously, the editor took everyone to experience the gasoline-electric showdown of the winter evaluation of Undercarriage. Regarding the active safety test of pure electric vehicles and fuel vehicles of different levels under harsh winter ice and snow conditions, what different tests will Undercardi bring us today? Without further ado, let’s watch together.
Understanding Chedi New Energy Winter Testing of Oil and Electricity Duel
The first thing we bring to you is the test of the vehicle in a static environment. The test simulates winter travel and encounters extremely harsh environments with heavy snow and road closures. On the premise that the vehicle has only 100 kilometers of range left, which model can last the longest with the vehicle stationary and the air conditioner turned on, among fuel vehicles, pure electric vehicles, and plug-in hybrid vehicles. This test is a simulation of waiting for rescue in an emergency situation during winter travel. At the same time, the test can also positively reflect which of the three models of fuel, pure electric, and plug-in hybrid has the highest comprehensive energy utilization when idling in place and turning on the air conditioner.
The vehicles participating in the test are from left to right: Lantu Dreamer, BYD Dolphin, and Buick GL8
The vehicles participating in the test are the Buick GL8 represented by the fuel model, the BYD Dolphin represented by the pure electric model, and the low-carbon version of the Lantu Dreamer represented by the plug-in hybrid model. The main reason why these three cars are selected as contestants for this test is because the Buick GL8 is the choice of many families during holidays. The hybrid Lantu Dreamer is the competitor of the Buick GL8. The performance of the BYD Dolphin equipped with a heat pump air conditioner is worth looking forward to, and the main reason why it leapfrogged the competition is because so far there is no pure electric MPV model for mass production delivery.

In order to ensure the fairness of the test, the three vehicles were parked stationary for the same time in the same environment in the test venue. At the beginning of the test, the three vehicles turned on the air conditioners at the same time and set the temperature to the same 24 degrees. One hour after the air conditioner was turned on, the interior temperature of the Lantu Dreamer reached 22 degrees Celsius, the interior temperature of the Buick GL8 was 21.3 degrees Celsius, and the lowest temperature in the BYD Dolphin was only 18.5 degrees Celsius. While maintaining the record of temperature changes in the car once an hour, the final plug-in hybrid contestant Lantu Dreamer lasted for nine hours and won the first place. The second place Buick GL8 lasted for five hours and fifty-eight minutes. The final time of the pure electric contestant BYD Dolphin was four hours and forty-three minutes.

In the face of cold weather of more than 20 degrees below zero, electric vehicles already consume electricity, and BYD Dolphin is a leapfrog challenge. The insulation materials in the car and the insulation capacity of the entire vehicle are naturally not on the same level as MPV models that are several times more expensive. Therefore, this test also tells us that the power and heating efficiency of the air conditioner itself are one aspect of the heating effect of the vehicle's air conditioner in winter. The overall heat preservation capability of the vehicle is also very important. The Lantu Dreamer can achieve such results because, as a plug-in hybrid model, the heat energy generated by the engine can heat the vehicle, and the kinetic energy output by the engine can also charge the battery. Therefore, its overall energy utilization efficiency is higher than that of pure fuel vehicles such as the Buick GL8.

After the static competition, the next step is the exciting dynamic competition. On the one-kilometer-long ice and snow track, pure electric vehicles and fuel vehicles will have a one-on-one confrontation. Compare the same level to see who can run faster on the ice and snow track and whose control is better.
The contestants in the first group of competitions were all models with relatively affordable prices. The oil train group sent the Geely Emgrand , and the electric train group sent the BYD Dolphin. Although both cars pushed their heads when entering the corners on the ice and snow track, because the ESP of the Geely Emgrand could not be completely turned off, the overall performance of the BYD Dolphin was better than that of the Geely Emgrand. The BYD Dolphin also brought the first race victory to the tram team.

The price of the vehicles of the second group of contestants has reached the range of about 150,000 yuan. The oil vehicle group is Changan UNI-V, and the electric train group is Aian AION S. Although Changan UNI-V's ESP can be completely turned off, it unfortunately slipped too seriously on the ice and snow track and had to be turned back on. The AION S, which cannot completely turn off ESP, performed relatively smoothly. In the corners, the steering of the two cars was clear and the suspension support was strong. However, due to its own weight, the AION S was more aggressive than the Changan UNI-V. In the end, the Changan UNI-V regained the victory for the oil crew with a slight advantage.

The price of the third group of contestants directly reached the level of 300,000 yuan. The oil car group competes with sports cars representing the BMW 3 Series, while the electric car group competes with the BYD Seal four-wheel drive performance version. The rear wheels of the BMW 3 Series with ESP completely turned off when starting started to slip severely, and when cornering, the vehicle rolled sideways like a crab. BYD Seal, which could not completely turn off ESP, was quite stable both in starting and cornering. In the end, BYD Seal scored another point for the electric train group.

The fourth group of contestants is an executive model in the range of 500,000 yuan. The oil train group sent out the familiar Audi A6L, and the electric train group took on the challenge of the Mercedes-Benz EQE. The four-wheel drive Audi A6L with quattro performs with ease whether it is starting or cornering, and beats the Mercedes-Benz EQE in the competition.

The fifth group began with contestants coming to the SUV model. The first to start the showdown was the Toyota Highlander in the gasoline group and the Nissan Ariea in the electric group that had just been launched. Although the Toyota Highlander has a slight head push when cornering, the overall performance is quite smooth. The Nissan Ariea is more powerful, but its own vehicle weight and the limitations of ESP caused the head to push more seriously when cornering, and ultimately failed.

The sixth group competed in the same field. The oil car group entered the BMW X3, and the electric car group sent the Zero Run C11. Although there is a significant difference in the selling price of the two cars, the power data of the Zero Run C11 can be said to be ahead of the BMW X3. At the beginning of the race, with the support of four-wheel drive, the BMW X3 handled the ice and snow track quite calmly. ESP did not restrict the vehicle too much, and its attitude and power output when entering and exiting corners were very good. On the other hand, in the Leapmo C11, the vehicle skidded after turning off ESP, and the vehicle's power was correspondingly restricted after turning it on. In the end, the BMW X3 won the race.
BMW Although the two are of different grades, their similar selling prices still make many people compare them together. Looking at the competition, the Volvo XC60 performed quite well. The vehicle's power was not restricted too much, and the slight push when entering and exiting corners could be adjusted in time. The performance of the Xpeng G9 is also very good, but the finishing time is still slightly behind the Volvo XC60.
The last group competing was the BMW X5 in the petrol train group and the NIO ES7 in the electric train group. Unlike the BMW 3 Series, the BMW X5 cannot completely turn off ESP, but it does not limit the vehicle's power too much during the race. With its strong power and stable electronic control system, NIO ES7 finally crossed the finish line first.

Summary:
We can also see through the test that the petrol vehicle team finally won five games. The reason is because the fuel vehicle itself is lighter than the pure electric vehicle, and the ESP system can help correct the vehicle's posture in time to bring a better driving experience. It seems that in order to cope with the extreme driving environment in winter and driving on icy and snowy roads, pure electric models still have a lot to improve.
