Range extension is also very different from range extension. Why can AITO achieve twice the performance and half the fuel consumption?

A few days ago, Yu Chengdong said again in an interview with the media: “It is better to buy a fuel car now than to buy an extended-range car.” According to the latest delivery data in September, AITO’s delivery volume reached 10,142 units. If not for a component manufacturer affected by the epidemic, the original delivery volume was expected to reach 16,000 units, firmly occupying the forefront of high-end new energy SUV sales.

Yu Chengdong is also very confident in future sales, and believes that AITO’s current order situation and consumer preference, as well as the ability to sell 20,000 per month. As a brand that was born less than a year ago, Yu Chengdong answered why AITO insisted on the route of increasing the range, why it was able to achieve such rapid growth, and Huawei’s planning in the automotive field.

In Yu Chengdong’s view, the biggest advantage of the extended range is that compared with the fuel vehicle, it “doubles the performance and saves half the fuel consumption”. Compared with the pure electric vehicle, the convenience is greatly increased. The fuel tank is equivalent to 200 kWh of electricity. The cruising range is equivalent to 240 kWh, more than 1,000 kilometers. As a large SUV, Wenjie M7 consumes only 5-6L of fuel without electricity, which is only half of the same level of fuel vehicles. The reason why AITO chooses to extend the range is the user experience, which is the technical choice that can provide the best user experience at present. This also enables AITO users not to be limited to those affected by policies such as license restrictions and travel restrictions, but also to directly compete with fuel vehicles.

A traditional large fuel SUV needs to be equipped with at least a 3.0T engine if it wants to reach 100km/h in 4 seconds, while the Wenjie M7 can easily surpass it with a 1.5T range extender and a motor independently developed by Huawei. Many people think that electric drive means fast acceleration and no technical content. Although the power density of the motor is high, it also has heat dissipation problems. Therefore, many new energy vehicles limit the maximum speed to prevent the motor from overheating and causing speed reduction or even demagnetization. The HUAWEI DriveONE motor used in Wenjie M7 uses oil cooling technology, which can effectively improve heat dissipation, reduce the average peak temperature of windings by 30°C, the peak temperature of magnetic steel by 15°C, and reduce the volume by 15%.

In fact, many people complain about the low technical content of range extension, which is unbiased in my opinion. Compared with pure electric vehicle technology, range extension will be more complicated. Not only there are many three-electric systems, but also high-efficiency range extenders must be added to ensure oil-electric conversion. efficiency. Although the structure of plug-in hybrid is more complicated than that of extended range, it is still the foundation of fuel vehicles in essence, and it is different from the extended range of pure electric drive in terms of ride comfort and performance. And from the actual effect, the difference in fuel consumption between plug-in hybrid and extended range is not obvious in most cases, and the fuel economy of the M5 in the media’s long-term measurement has surpassed many plug-in hybrid opponents.

Of course, the range extension technology only lays the foundation for the success of AITO. Huawei’s ability to grasp user needs and product definition is more critical. Like the Wenjie M7, it has the body of a large SUV but is very flexible in control. The secret lies in “digging space” from the car, reducing the space occupied by the power system through integration, and improving the user’s room rate. The riding space is comparable to BMW X7 and Mercedes-Benz. At the same time as GLS and other opponents, the turning radius is only 5.87m, and parking in the old community and turning around on narrow roads can be easily done.

The design in the cockpit can give full play to Huawei’s advantages in intelligence. The HarmonyOS smart cockpit on the ceiling of the car is connected to mobile phones, smart homes, and smart watches, and information from different devices can be seamlessly transferred. There is also the AITO zero-gravity seat that has been blown up by many car owners. Although this concept has been proposed for many years, AITO is the first to achieve commercial use, and it truly achieves the ultimate in comfort. In the AITO car, you can easily feel the extreme sense of luxury of Huawei products with all the functions just right.

Summarize:

China’s new energy vehicles can be said to be the most “rolling” market. There are dozens of brands, large and small. There are traditional car companies, new forces and various cross-border players. In order to succeed, you must have strong technical strength. Yu Chengdong said that the main players in the smart car industry in the future may be in the lead. Huawei does something in the automotive field and does not do it. It will empower the automotive industry in its own areas of expertise, so that the entire end-to-end solution can be achieved in China. Leading, global leading.

As an automotive brand deeply empowered by Huawei, AITO brings not only advanced technology applications to the automotive industry, but also Huawei’s long-term product concept. Product design starts from user needs and maximizes product experience. At present, the sales of Wenjie M5 and Wenjie M7 continue to rise, Wenjie M5 EV is ready to go, and Yu Chengdong has done it again for the car!
