　　The original title of the article: Not only close to the people but also safe, Hongqi H5 door/anti-collision beam dismantling　

　　Hongqi may be one of the few Chinese brand cars that can make most consumers feel emotional about it today. As a brand with a lot of halo and aura in China, it always seems to give people a feeling of being out of reach. However, this impression was broken with the launch of the mid-sized Hongqi H5 (hereinafter referred to as H5). Whether it is the price range or the appearance, the H5 is close enough to the people, changing the image of the official car that Hongqi gave people in the past. In September this year, the Hongqi H5 participated in the C-NCAP crash test based on the latest rules, and also received a five-star good result. Now we have the experimental car participating in the side collision, and we can see how the Hongqi H5 performs in terms of doors and collision beams through it.

　　The model dismantled this time is the intelligent version of the 2018 Hongqi H5. In terms of passive safety configuration, in addition to the head air curtain and rear seat belt unfastened reminders compared with the entry-level version, it is the same as other models in the whole series. This difference will not have any impact on the door and collision beam structure, so it has strong reference significance.

　　Since the H5 has participated in the C-NCAP crash test, let’s review its performance in the test before dismantling the car. From the overall score point of view, the H5’s comprehensive score rate is 87.5%, which meets the five-star rating standard of C-NCAP.

　　– Front anti-collision structure

　　Since the actual dismantled test car participated in the side crash test, the structure of the front and rear of the car was not affected by the collision. So how does the Hongqi H5 do in the collision avoidance part of the vehicle head? Let’s take it apart and take a look.

　　Everyone knows that when a vehicle is in a frontal collision, the strength of the front collision beam will have a great impact on the collision result, so in the design, high-strength materials are usually used to absorb some of the collision energy through deformation. But on the other hand, after a collision with a pedestrian, if the soft bumper is not enough to cushion the force of the collision, will the pedestrian’s legs come into direct contact with the very hard front collision beam?

　　This kind of shield design can be seen on many cars, but in most cases, these resin shields are simply fixed in the front area of the car, unable to transfer the impact force in a frontal collision. However, on the Hongqi H5, the installation of this shield has some differences.

　　Hongqi H5 adopts a front anti-collision beam with a collapse design and a similar "mesh" structure, which has a better energy absorption effect than the ordinary double-layer stamped steel plate structure anti-collision beam.　

　　Overall, from the collision function area of the front part of the Hongqi H5, it has its own characteristics in terms of frontal collision and pedestrian protection, and the test results of C-NCAP can also prove that its design can work effectively in actual collisions and achieve the expected design goals.

　　– Front details

　　As a luxury mid-size car of a Chinese brand, the experience of details is also very important. For example, when opening the engine hatch, if you lift it lightly, it can slowly rise up by itself. The sense of high-end is often reflected in these infrequent details.

　　When the engine is running, the noise and vibration generated have always been one of the important factors affecting the comfort of drivers and passengers, so in the case of unable to reduce engine noise, how to isolate this part of the sound through external measures has become an important indicator to test the NVH characteristics of the whole vehicle.

　　The entire engine compartment of the Hongqi H5 is very orderly. In addition to the engine cover, resin trims are also arranged around the engine to cover the wiring harnesses inside the engine compartment and other places that look messy, creating a sense of sophistication visually. This approach is also in line with Hongqi’s brand positioning.

　　From the details of the front part of the car, the workmanship and materials of the Hongqi H5 in terms of NVH are still good. In some common places where sound-absorbing materials are installed, materials such as sound insulation cotton are more or less installed, which makes a significant contribution to improving the NVH characteristics of the vehicle.　

　　2 Rear anti-collision structure and door anti-collision structure

　　- Rear collision beam structure

　　The rear collision beam of the car body can reduce the damage caused by the rear-end collision of the car at low speed. Since there is no rear-end collision item in the general crash test, the quality or even the existence of the rear collision beam will not affect the test results. Therefore, some manufacturers have lowered the standard of the rear collision beam due to cost control and other reasons, or even omitted it. So how is the Hongqi H5 doing in the rear collision beam?

　　The rear anti-collision beam of Hongqi H5 uses a "mouth" structure, which has a certain energy absorption effect like the front anti-collision beam. The rear energy absorption box uses a more common square structure, and two collapse grooves can also be seen on it.

　　Although the anti-collision structure at the rear of the vehicle cannot be reflected in the crash test results, the structure of the rear anti-collision beam and energy absorption box of the Hongqi H5 meets the mainstream market standards and will not make people find any dissatisfaction.

　　Front and rear doors and details

　　We all know that when a vehicle is subjected to a side impact, the door will play a certain protective role in the passenger compartment. Not only that, but the workmanship of the door can also have an impact on the NVH characteristics of the vehicle when it is running. Judging from the side impact results of C-NCAP, the Hongqi H5 received a full score for the protection of the front driver in the side impact, but lost more points in the chest subdivision of the rear passenger. So what about its structure inside the door? Let’s take a look at it together.

　　From the front door structure after the collision, the inclined door collision beam not only participated in the collision, but also maintained a good structural state after the collision, and no obvious deformation was found. This can play a very effective role in protecting the occupants of the driver’s seat. The front door performs so well, let’s take a look at the rear door.

　　The colorful imprints left after these collisions all demonstrate that in the event of a side collision, the side airbags and air curtains can be ejected promptly and quickly, and the ejected positions are not offset, which can effectively protect the driver and occupants.

　　Summarize:

　　Judging from the crash test results of C-NCAP, the five-star score of Hongqi H5 is enough to be called excellent. In the structural part of the crash, its design meets the mainstream standards in the market, the safety structure of the door and collision beam is complete, and there is no room for cutting corners. In terms of NVH sound insulation and vibration filtering, you can see the use of a lot of sound insulation and sound-absorbing materials. With its dynamic appearance and honest materials, Hongqi has shown consumers that they want to have more consumer fans through the H5, and from the increasing visibility on the road, it can be seen that it has indeed achieved this.

On January 22, Lantu announced the formal signing of a strategic cooperation agreement with Huawei. It is reported that the two parties will jointly create the ultimate intelligent travel experience around user requests according to their respective field advantages, and accelerate the large-scale commercialization of intelligent technology through innovation and exploration in multiple fields through cooperative models.

Landmap said: "Huawei’s deep accumulation in ICT technology and continuous breakthroughs in the field of intelligence will help Dongfeng Landmap to further upgrade and iterate in the field of smart new energy vehicles."

In the eyes of industry insiders, the cooperation between the two parties may adopt the Huawei HI (Huawei Inside) model. Under this model, Huawei and cooperative car companies jointly develop, and the cooperative models will be equipped with Huawei’s full-stack smart car solutions. At present, there are three car companies that have adopted this cooperation model: GAC Aian, BAIC Extreme Fox, and Changan Avita.

With Lantu joining Huawei’s cooperative car companies, Huawei’s automotive portfolio has expanded again.

With Baidu, why cooperate with Huawei?

Huawei is not the first tech giant to partner with Landmap.

In 2022, Lantu announced the formation of an effective technical alliance with Baidu. Lantu said that it will use Baidu’s technology in intelligent driving and intelligent cabin to create leading high-order intelligent driving assistance, intelligent human-machine interaction, intelligent networking and other technologies.

Then in 2023, the new Landmap FREE, equipped with Baidu Apollo’s pilot assist driving function, was officially launched.

In the field of smart cars, Huawei and Baidu have many of the same businesses, and intelligent driving is one of the core areas of overlap. Will this cooperation with Huawei, which is also a leader in the field of autonomous driving, change the cooperation between Landmap and Baidu?

Times Finance asked Landmap for information on this. As of press time, the official has not replied.

A person close to Huawei told Times Finance that the cooperation period between the two parties is long and is still in the early stage, and more information is expected to be announced one after another.

New Travel CEO He Lei revealed on the evening of January 21 that the cooperation between Lantu and Huawei will adopt the HI model, and subsequent products will be equipped with Huawei’s Hongmeng car machine and ADS (Huawei high-end intelligent driving system). However, self-developed businesses such as Lantu car machine system should also be retained, and its product portfolio may be a high-end and low-end matching model in the future.

Times Finance asked both companies for details on the specific content of the cooperation between Lantu and Huawei, and the responsible person of Lantu and Huawei replied that "there is no more information at present".

As a high-end new energy vehicle brand under Dongfeng Company, Dongfeng attaches great importance to the Lantu brand.

On July 29, 2020, at the Lantu Automobile brand strategy conference, Zhu Yanfeng, then chairperson and party secretary of Dongfeng Company, personally stood on the platform and explained the brand strategy and future planning of Lantu Automobile.

"We are committed to building Dongfeng Lantu into a leader in high-end new energy passenger vehicles in China. From 2021, no less than one new car will be launched into the market every year. In the next three to five years, Dongfeng Lantu’s products will cover various market segments such as cars, SUVs, MPVs, crossovers, and high-performance vehicles." Zhu Yanfeng said that the launch of the Lantu brand has opened a new round of hard work for Dongfeng to develop high-end brands and promote brand improvement.

Compared with other new car-making forces, the market performance of Lantu in 2023 is not impressive. According to the data provided by Lantu, its overall sales volume in 2023 was 50,552, with an average monthly sales volume of 4,212. However, in the second half of last year, Lantu’s vehicle deliveries began to rise rapidly, and it exceeded 10,000 in December.

At present, there are three models on sale in Lantu Auto, namely Lantu FREE, Lantu Chasing Light, and Lantu Dreamer. Lantu told Times Finance that the above three models will still be the main sales force in 2024, and a new car is planned to be released, but the timing is undetermined.

The debate between Huawei HI model and Smart Choice model intensifies

With the addition of Landmap to Huawei’s automotive map, the competition within Huawei’s automotive business will become increasingly intense.

Some people believe that the sales of BAIC Extreme Fox, Changan Avita and other brand models under Huawei HI mode are not bright. If Lantu and Huawei adopt HI mode this time, the effect remains to be seen.

Dcar data shows that in 2023, the sales volume of Changan Avita brand cars under the Huawei HI model was only 23,485; the annual sales volume of BAIC’s Extreme Fox α coefficient S series models, including the HI version, was only 15,163.

*** is the smart selection model. Since the second half of last year, with the hot sales of products such as M7, the cumulative sales of the Q brand under the smart selection model will increase to 94,380 units in 2023.

The HI model and Huawei Smart Choice model are both new cooperation models between Huawei and car companies. According to Huawei, in the HI model, car companies dominate, the underlying intelligent driving functions are provided by Huawei, and the car companies are responsible for product decision-making and experience; under the Smart Choice model, Huawei has a higher degree of participation, and it has a greater voice over product definition, design, channel sales, brand operation, etc. At present, car companies that adopt the Smart Choice cooperation model include Cyrus, Chery, Jianghuai, etc.

For different cooperation models, the attitude of each cooperative car company is also different. Recently, Zhu Huarong, chairperson of Changan Automobile, made a unique evaluation of Huawei’s HI model, highlighting the complex attitude of car companies towards the cooperation model with Huawei.

"Why doesn’t [Changan Automobile] work with Huawei to develop a smart selection model, why does it want to develop a HI model? First, Changan’s strategy is that cars must have their own brand, not someone else’s brand. If it is someone else’s brand, it will be wrong. Second, Changan must do things in line with the requirements of the national industrial policy, because I think other models are problematic." Zhu Huarong said on January 16.

In Zhu Huarong’s opinion, the cooperation model needs to clarify the attribution of responsibility. Under the HI model, any time there is a problem, Avita and Changan Automobile are responsible.

At the signing site between Lantu and Huawei, Huawei was represented by Xu Zhijun, vice chairperson and rotating chairperson of Huawei, and Jin Yuzhi, CEO of Huawei Smart Car Solutions BU. However, the "key man" of Huawei’s automotive business – Huawei managing director, end point BG CEO, and chairperson of Smart Car Solutions BU Yu Chengdong did not appear.

According to a previous report by Economic Observer Network, Yu Chengdong is a representative of Huawei’s internal "car-making faction", and Xu Zhijun, who previously promoted Huawei’s car BU independence, is a firm "no-car-making faction". That is to say, Xu Zhijun more supports the HI model as a supplier, while Yu Chengdong more supports the smart selection model of deep participation in car-making.

"We Lao Yu [Yu Chengdong] are not convinced, but he only has one vote. As the head of the consumer business, Lao Yu wants to build cars from the start of consumer BG," Xu Zhijun said at the 2021 Huawei Technology Conference.

The appearance of Xu Zhijun and Yu Chengdong’s absence this time also added more uncertainty to the competition between Huawei’s HI model and Smart Choice model.
