Tesla Model 3' s winter endurance challenge, low temperature+high speed only runs 252+28km.

The year is approaching, unconsciously our? The # Pure Electric Vehicle Winter Endurance Race # test has been carried out on the fourth vehicle. As the final battle of this event, the protagonist of this test is also very concerned-Tesla Model? 3。

The rules remain unchanged. In this test, we are still cooperating with Shanghai Media Car Gathering Network and Guangzhou Media Electric Planet. Tesla model? 3. Start to simulate the long-distance travel conditions of urban car owners in winter. Of course, the route is basically the same as the previous test.

What needs to be explained is that for various reasons, our Beijing line got imported money? 3 standard battery life upgrade, Guangzhou line is imported? 3 long battery life version, and the Shanghai line got the domestic model? 3 standard battery life upgrade.

The models tested by the three lines are different, which does not well reflect the influence of temperature on the endurance of the same model. But on the other hand, it's convenient for us to be a model? 3 directly compare different models and have a certain understanding of the real endurance performance.

Let's take a look at our test car. The above table is a bit complicated, because the imported version of the upgraded version of the standard battery life has been discontinued in China, so the price has gone a rough range; NEDC has two cruising range figures because this car was marked with 480km on its official website page last year. Later, this imported model was rolled off the assembly line in official website. We can only compare the battery capacity on the nameplate with the models in the list of models exempted from purchase tax published by the Ministry of Industry and Information Technology, and judge that the car should be a 53-degree battery, that is, a 455km model according to the national standard working condition method.

Considering the current domestic model? The batteries used in the upgraded version of the standard battery life and three-battery system are the same as those in the imported version, and NEDC and the national standard working condition method are basically the same. In order to compare with the domestic version of Shanghai Line, we also calculated the final discount rate according to the theoretical value of 455km.

Anyway, according to the plan, our test route will be as consistent as the previous three times, starting from Beijing's Northwest Fourth Ring Road, passing through North Fourth Ring Road, East Fourth Ring Road, G 1 Jingha Expressway and G25 Shen Chang Expressway, and finally reaching Liuzhangzi Service Area in Chengde City, Hebei Province. The whole line is 296.9 kilometers, including 264 kilometers in expressway, accounting for 89%, and 32.9 kilometers in urban roads and loops, accounting for 1 1%.

It should be an ideal working condition for long-distance travel, with high speed as the mainstay and few urban roads. Of course, in order to ensure the unity of the influencing factors in the three places, we have made unified settings for the vehicles before departure, including:

Driving mode: energy saving;

Air conditioning temperature: 22℃, automatic wind speed;

Tire pressure is calibrated one by one;

Clear the small table;

Each car includes three drivers;

Fully charge the vehicle before departure, with a cruising range of 368km, which is an indicator under EPA working conditions in the United States. According to the owner, in fact, it should be able to reach 380km when fully charged, and the battery life on the test day is low, which may be affected by temperature.

After the preparation is completed, we will set off at 10: 30 am, take the figure of 368km as the initial mileage of this trip, record the remaining mileage of the vehicle every 10km, and finally summarize it into a table.

The day of the exam happened to be the "March 9th" in Beijing, which was the coldest time of the year in Beijing. The weather forecast temperature is -7~2℃, our departure temperature is 0℃, and the overall temperature is not higher than 2℃. We speculate that this low temperature around zero may have a certain negative impact on the endurance performance of this car.

It is worth mentioning that it may be because of the trust in autonomous driving, or it may be because the roads are mostly high-speed and the road conditions are good. Our main driver Gigi frequently turns on the AutoPilot advanced assisted driving function throughout the journey. In his own words, AP is the best ADAS system at present, and there is no one. Unfortunately, the car we got was only equipped with the basic version of AutoPilot without FSD, so we missed Tesla's automatic lane change and NOA function.

Fortunately, this trip did not encounter the dilemma of heavy snow road closure like the first and second tests, and we were able to follow the original route, that is, basically at full speed. But surprisingly, models? 3' s power outage speed is faster than we thought: when the meter lasts 98km, we are still 95km away from the terminal Liuzhangzi service area, that is to say, the model? It is very likely that you will not be able to "complete the game".

Finally arrived at Jinzhangzi parking area at 1: 47 pm, more than 40 kilometers away from the finish line. The key data are as follows:

The total mileage is 251.9 km; ;

The remaining mileage is 28 kilometers; ;

Excluding waiting and rest, the total driving time is 195 minutes and the average speed is 77.5 km/h;

The average power consumption is 17kWh/ 100km.

The data recorded in detail are as follows:

It can be seen that even Tesla, which has excellent three-electric system, still has a big gap between the actual battery life and the apparent battery life in Beijing in winter. In order to facilitate your understanding, we have arranged the data into a line chart, and you can compare them.

And if you compare the three cars tested before, the line chart is like this:

It is not difficult to see that Tesla model? There is no obvious difference between the endurance decline curve of 3 and Tucki G3 and Weilai ES6. Weimar EX5 declined even more, but in the end, although it showed endurance of 0, it still glided to Liuzhangzi service area by "emergency power".

To be honest, the result was unexpected. When we customized the winter endurance race plan, we thought that due to Tesla's technical advantages in the three-electric system, it is likely that the endurance discount is the lowest among the four cars. Even if its full-charge cruising range is at least 455km, it should not be a big problem to actually run 300km.

But judging from the final discount rate, what is the model? The discount on endurance is actually quite high, with a discount rate of 59.9%. In fact, it is not as "real" as many friends imagine, and the battery life is more "real" than domestic cars. What's more, besides models? All but three of the three cars are SUV models. Theoretically, the drag coefficient is higher than that of a car model. Worse, driving at high speed costs more electricity.

Is it possible that the temperature in Beijing is too low? It is indeed possible, as mentioned above, that the model? The highest temperature on the test day is only 2℃, while the highest temperature on the test day in Tucki G3 and Weilai ES6 can reach 5℃, which definitely has an impact, but how much the temperature difference of 3℃ affects the battery life is debatable.

Besides, we also got some domestic models of Shanghai Line? 3 Actual operation data:

On the way: the traffic jam is serious, driving? What is the apparent endurance after 243.5km? 0, what is the discount rate? 55%, apparent power consumption? 19? Degree.

Return: Have a good trip. Drive? What is the apparent endurance after 252.8km? 10km, what is the discount rate? 58%, apparent power consumption? 18.5? Degree.

This is very interesting. The highest temperature in Shanghai on that day can reach 10℃, and the ambient temperature remained basically at 9~ 10℃ during the whole test period, but the discount rate they ran out was even lower than that of our Beijing line. You know, the current domestic model? The battery used and the other three electric systems are imported, which can be said to be no different from our test car in Beijing.

Of course, our test is broadcast live. If you have any questions about this test, you can now learn how we drive, test and record by watching the replay.

Then we can draw the conclusion that if it is a long-distance working condition dominated by high speed, the discount of about 60% should be Model? 3 standard endurance upgrade This model has normal endurance performance in winter, which may be better than some domestic models, but it has no obvious advantage.

Crucially, because the battery pack capacity of this car is only 52.8kWh, and the battery life in NEDC is only 455km, the actual mileage of this car in winter may be lower than that of NEDC models with larger battery capacity and higher battery life. Even if Tesla has an excellent three-electricity system, it can only run at a high speed of about 250km, which is already the relative limit.

If you care about battery life, or consider buying this model because of Tesla's excellent battery life performance, our suggestion is to wait for a long battery life version, model? 3 standard endurance upgrade The endurance performance of this model is actually not as good as expected, and Tesla is somewhat overestimated in some aspects.

Of course, our test is only for battery life, and Tesla's advantages are not only reflected in battery life. Tesla's AutoPilot, FSD, OTA, super charging, performance, driving experience, etc. Are advantages that cannot be ignored. Any one of them is enough for you to buy a model? Sufficient conditions of 3.

So far, all four models of 20 19 pure electric vehicle winter real endurance competition have been tested. Later, we will launch the summary report of Beijing Line. If you are interested, please continue to pay attention to electricians!
