"The endurance of the AITO M5 is really strong!"
This is the evaluation given by Yu Chengdong, managing director of Huawei, CEO of Consumer BG, and CEO of Huawei's intelligent car solution BU, on the AITO Q&A M5 car. "On the morning of the second day of the Chinese New Year, I drove back to Shenzhen from my hometown in Anhui Province, 1400 kilometers one way, using the fuel priority model, only adding a little fuel to the highway service station, and completed the whole journey."
As for the amount of "a little oil", we do not know from his illustrations. This way of describing it is similar to the tone used by Yu Chengdong when introducing the M5 at the Huawei Winter Flagship New Product Conference last December: "The chassis of our car is the chassis of the Million Luxury Car", "Our mileage is basically 3 times that of normal electric vehicles, and it kills a lot of pure electric vehicles"...
At that press conference, Yu Chengdong used a lot of contrast techniques to raise the product competitiveness of the M5, which attracted the disgust of some netizens, because after all, everyone had not really experienced it. But this time is different, through his own personal experience of long-distance self-driving, he proved that the extended range electric vehicle is better than the pure electric vehicle, and has a better product experience in the long-distance travel scenario.
Compared with the "add a little oil" can run through the 1400 km extended range electric vehicle AITO Qijie M5, Yu Chengdong believes: "If you drive a pure tram, cold winter + high-speed wind resistance, winter can only run more than 200 kilometers, I need to charge at least 6 times on the highway, each charge for 1 hour, at least 6 hours of electricity, in any case, can not get home in a day." ”
What Yu Chengdong said about this matter is indeed reasonable.
First, the oil-burning tram is a high-speed artifact?
Winter and high speed are the two major dead holes of pure electric vehicles, and it just so happens that the Spring Festival trip will be encountered.
This year's Spring Festival, Song Wen drove his Model 3 standard endurance version and returned to his hometown of Nantong, Jiangsu From Beijing. The journey is about 1200 kilometers, and the navigation display time is about 12 hours. On the way, he charged a total of 6 times at the charging station in the high-speed service area, each time charging half an hour to an hour or so, and 17 hours to home. On the return trip, he chose to go to the Tesla supercharge station at the high speed, and only charged it 4 times, which took about 18 hours.
The round-trip time includes one queue at the charging station in the high-speed service area, one queue at the Tesla supercharging station, and the time to sleep a little more during charging, "I estimate that not sleeping can save 2 hours." Subtracting the 2 hours of the break, he had 3-4 hours more than the navigation expected, which is about 15 hours.

Time, in terms of the 7-day Spring Festival holiday, is more precious than money. Know that if you charge for an extra hour and queue for an extra hour on the road, it means that you will lose an extra hour of time to spend with your family. Therefore, in the long-distance experience of opening the extended-range electric vehicle to ask the M5, the most touching point for Yu Chengdong may be that he added in the comments: "Thousands of miles a day, no worries."
According to Yu Chengdong, his relatives drove the M5 from Shenzhen back to his hometown in Anhui province in one day, ran 1400 kilometers a day, and added oil in the middle to get it done (meaning that there was no time to charge). On the return trip, Yu Chengdong drove himself, rested in the high-speed service area to go to the toilet, and added 1 to 2 times of partial oil. Although Yu Chengdong did not disclose the total length of time, according to the data displayed by the navigation, the time between Shenzhen and Lu'an is about 14 hours, counting the time for rest and his refueling, 15 hours is enough.
In this comparison, an electric vehicle with an extended range of about 15 hours can run 1400 kilometers, but a pure electric vehicle can only run 1200 kilometers in 15 hours. This is reminiscent of what a pure electric car owner who was queuing in the service area during last year's National Day said: "I am still charging on the highway, my friend has arrived home."
Of course, range-extended electric vehicles will also be affected by low temperature and high-speed conditions, and the endurance will also be discounted - so-called, afraid of cold and afraid of high. Because the engine of the extended range electric vehicle is only involved in power generation, it only relies on the power in the battery to drive the motor, thereby driving the vehicle.
First of all, the fact that the winter endurance is shorter has long been the default fact in the hearts of electric vehicle owners. In the previous "can't afford to wear a goose, don't buy an electric car", the author mentioned a reason: at low temperatures, the electrolyte becomes viscous, at this time the lithium ion responsible for discharge is difficult to pass, then the discharge effect will be "greatly discounted", and at the same time, the activity of lithium ions will be reduced, and they are "lazy to move". The final result is that the actual mileage is completely inconsistent with the mileage calibrated by the car company.
Secondly, driving high speed in winter is more difficult for electric vehicles. According to DriveElectric, driving 55mph (about 88km/h) has a 25% more endurance than 70mph (about 112km/h). For the problem of poor high-speed endurance, in the previous "Who ruined the holiday of the tram owner?" In the book, the author also mentioned a reason: pure electric vehicles generally use electric vehicles single-speed transmissions. When the speed of an electric vehicle is increased above a certain range, the torque will decrease, and torque is the element of the vehicle to overcome the resistance. As a result, the acceleration of the vehicle becomes slower, the energy consumption becomes higher, and the efficiency is reduced.
However, because of the increased range electric vehicle, it better solves the two problems of "fear of cold" and "fear of height".
On the one hand, by using the waste heat generated by the operation of the engine, it provides a part of the heat in the cockpit and the battery, so as to avoid the two energy consumption problems of battery heating and cockpit heating. On the other hand, because there is an engine to generate electricity to supplement the battery, as long as the fuel conversion efficiency is improved, the same tank of oil can run farther, and the estimated fuel consumption of 100 kilometers is naturally lower.
Although Yu Chengdong did not mention the actual fuel consumption of the long-distance running of the Q&I M5, according to the data given by the Ministry of Industry and Information Technology before, the WLTC fuel consumption of the M5 is 6.69L/100km, and the fuel tank volume of 56L can indeed be realized as Yu Chengdong said, only once the oil is added, the 1400 km trip can be completed.
The AITO Q&A M5 on display in the Huawei store
For reference, Landu FREE, which also uses range extender technology, consumes 7.9L/100km of WLTC fuel registered with the Ministry of Industry and Information Technology. The author opened the ideal ONE from Beijing to Hunan during the Spring Festival holiday, driving 1500 kilometers and consuming 135L of fuel, about 9L/100km. And, at least three times of oil is added each one-way trip. (I guess yu Chengdong's "little oil" is probably an allusion to the ideal ONE oil)
From the data point of view, after the M5 was replaced with an H15RT (engine codename) generator, the power generation efficiency was among the highest in the industry, and the official power generation efficiency was 3.2kW·h/L. In addition, there is a detail, Huawei's three-in-one electric drive system in the motor uses oil-cooled heat dissipation, compared to the previous generation of Cyrus SF5 can ensure a more sustainable output in the continuous overtaking, high-speed cruise and other harsh conditions. In addition, Yu Chengdong also added a sentence that "NVH mute is very good, the noise suppression effect of high-speed driving is good, and long-distance driving is not so tired." ”
Of course, whether the car "built" by Huawei is good or not, you still have to try it yourself to know.
Second, please believe Yu Chengdong again
Under Yu Chengdong's Weibo, many netizens left comments such as which oil truck can't do it every day. For example, netizen @ Fujiwara Egg Egg: "Honda mix, Thunder mix a tank of oil can be the same mileage as you." There are also netizens @ Vienna E major: "How much is it to add a little?" If it is two full tanks of fuel, is it not normal to run more than 1,000 kilometers at high speed? ”
In fact, Yu Chengdong's way of publicizing and carrying goods is very simple, that is, TianJi horse racing. And pure electric vehicles than the convenience of battery life and energy replenishment, and fuel vehicles than cost, performance and intelligence.
Don't be in a hurry, this kind of "field horse racing" competition method is confirmed by the ideal ONE, and it is feasible. In the December 2021 high-end SUV ranking, the Ideal ONE ranked second with 14,000 units, surpassing the BBA's long-selling fuel models, mercedes-Benz GRC, Audi Q5, BMW X3. In the annual sales ranking, it still ranks fifth with a data of 90,000 vehicles, which forces volkswagen Tuang.
First of all, in terms of the cost of using the car.
In addition to enjoying some city license preferential policies and purchase tax exemption policies, the reason why the range extender is more popular than many plug-in hybrid models on the market now is because they all use a large-capacity battery, which is enough to support the daily commuting needs of users. Equipped with an ideal ONE with a 40.5kWh battery pack, the WLTC has a pure electric endurance of about 150km, and the Qention M5 equipped with a 40kWh battery pack has a pure electric endurance of 150km (working condition method). If there are charging conditions at home, the cost of urban commuting can be further reduced.
Second, re-compare performance.
For example, you go to take the "weak performance" ideal ONE in the extended range electric vehicle, and its "nemesis" Volkswagen Tuang to compare, choose to the Top model of Tu Ang nearly 400,000 yuan, the 2.5T V6 engine to get the maximum power of 220kW data, and the ideal ONE relies on dual motors to easily achieve a maximum power of 245kW.
The M5, which uses Huawei's three-in-one electric drive system, has come up with a maximum power data of 365kW, which is no wonder that Yu Chengdong said at the press conference: "Comparable to the ultimate performance of supercars." Indeed, in addition to the subjective feelings of chassis and control, extended-range electric vehicles rely on the more linear power output of the motor, which reduces the dimensionality of the fuel vehicle in terms of performance.
Finally, it's better than the smart piece.
The older generation of fuel models, limited by the space of the chassis architecture, wiring harnesses and other reasons, can not or can not be so easy to achieve intelligence. In addition, fuel vehicle companies pay more attention to the competition of electric vehicles, and have no time to take care of the iteration of fuel vehicles. Like before, Roland Berger analyzed in the "2021 China Intelligent Vehicle Competitiveness Index White Paper" that at present, OEMs tend to use electric vehicles when pushing new models, and new intelligent technologies are mainly used in new models, resulting in new intelligent technologies being reflected more in electric vehicles.
For example, Huawei's full-featured HarmonyOS smart cockpit did not give other fuel models to make a debut, but left it to Yu Chengdong to hold in the palm of his hand. Here we use a small function to spy on how deep the software and hardware control of Huawei is in the M5 car.
Petal Maps – This is Huawei's first map app in China.
For example, it can realize the third-party application location information to be shared to the car machine, the mobile phone and the car can easily connect the navigation path between the car and the machine, and the car machine can also transfer the walking navigation back to the original mobile phone map application. After arriving at the parking point, if there is still a remaining distance to walk, you will receive a map prompt on your phone after getting off the car, click Start Walking Navigation Mission to continue to follow the navigation to your destination.
For example, such as entering the basement or when night falls, Petal Maps will automatically switch to dark mode according to the changes in the external environment; when entering the environment such as the tunnel, the vehicle will automatically open the internal circulation of the air conditioner to reduce the exhaust and dust entering the vehicle from the tunnel; during the driving process, the central control screen, dashboard, and HUD can be used as a carrier to display navigation information to avoid the main screen application switching affecting the navigation process.
It can be seen that although it is only a simple map function, it involves a series of underlying capabilities such as positioning, perception, execution, and so on. If a fuel vehicle wants to do this, it cannot be truly intelligent without a new set of electrical and electronic architecture. For example, the FUEL model BEIQI Cube, which is also known as the fuel model supported by Huawei technology, is only the most basic Hongmeng car machine OS system.
Write at the end
Having said that, it's not a single reason that extended-range electric vehicles are highly sought after.
Because the car is a barrel effect of the most obvious industry, in your short board will not be short to the barrel leakage situation, continue to lengthen your long board, in order to attract a part of the user in the market. But to do that, it's not enough for a new brand.
For example, when talking about the success of Tesla, Wei Jianjun, chairman of Great Wall Motors, said that the most important reason is intelligence, and then there is a reason for brand value, that is, the brand of founder Musk. "I think it's a tech-sleek consumption. You don't open a Tesla, you don't experience its intelligence, you feel a bit of a turtle and Out feeling. ”
Looking at it again today, Huawei and Yu Chengdong frequently asked for the station platform of AITO M5, not as simple as blowing product power, but like Tesla and Musk did, to establish a higher brand recognition for users. However, the extended range electric vehicle reduces the threshold and difficulty of entry, because to really talk about hybrid technology, domestic car companies still have to look at BYD, the Great Wall, and Geely.
But no matter what, the car he built himself test-drove first, and with this alone, he should choose to believe Yu Chengdong once.
