[Design Decoding] Driven by favorable policies and future development trends, more and more enterprises have begun to enter the team of new energy vehicles. In addition to the brands we are familiar with, Weimar Automobile and so on, there are many enterprises in the embryonic stage, and these new vehicle-making enterprises not only help the rapid development of new energy, but also promote the traditional car enterprises to further develop new energy. Today, our protagonist is the high-end pure electric vehicle launched by the traditional OEM. In the future, it will cut into the market segment to meet the needs of consumers for high-end SUVs.

　　Different from the pure electric vehicles such as ERX5 launched by Roewe before, MARVEL X is not a pure electric vehicle based on the replacement of powertrain for gasoline models, but a completely independent new model. Moreover, not only MARVEL X, but also MARVEL owned by Roewe will have a series of new energy vehicles focusing on the mid-to-high-end market in the future. From the design idea of this MARVEL X, we can see the difference between this MARVEL series and ordinary Roewe pure electric vehicles in the future.

● Appearance and coincidence 90%

　　MARVEL X was designed by the SAIC design team led by Shao Jingfeng, the design director of SAIC. At present, Roewe’s flagship pure electric SUV almost completely retains the previously released concept car in design. It is understood that the appearance overlap between the production version and the concept car is as high as 90%, so the MARVEL X in front of us looks very avant-garde.

　　At the beginning of MARVEL X design, the team led by Shao Jingfeng found the right direction and positioning. As the representative of Roewe brand pure electric SUV, it will enter the eyes of consumers. Different from the previously released pure electric vehicles such as ERX5 and Ei5, it will face the mid-to high-end market. The specific market demand throws them a difficult problem, and how to build a car that is more in line with this market demand is what this team needs to do. Then, after numerous brainstorming, they finally determined three key words to achieve this goal: strengthening brand recognition, emotional design and shaping a sense of high quality.

　　After the evolution of RX5, RX3 and i6, the rhythm design of Roewe brand has been well received by consumers, while the overall design idea of MARVEL X continues the concept of rhythm, and we can see the familiar Roewe from the design of the front of the car. The huge wingspan grille has been preserved in this pure electric SUV, and the front grille shape has not been cancelled like other new energy vehicles. This design style seems to make the whole car more powerful. The addition of light arc lights outside the grille not only enhances the visual effect, but also further deepens the brand image. Together with the "Arrow Feather", it will have a deep impression at first glance.

　　In the design of MARVEL X, there are also many similar design elements on RX5 and RX3, such as the waistline running through the car body and two arcs on the front and rear wheel arches, so that the sides will not look too rigid. The design of the rear of the car is not the same as that of the previous Roewe models. First, the license plate frame is moved down to the rear enclosure, and the rear of the car looks simpler. It also has a waist-closing design, and the lower plate looks quite solid.

　　We can see that in MARVEL X’s design language, dynamic modeling occupies a key position. MARVEL X, as an SUV, has a lower body than traditional SUVs, and the identity of pure electric vehicles also gives designers more room to play. Its visual center of gravity is more backward, and the low-cut, slender body with a small proportion of the rear window creates a visual feeling of diving forward. At the same time, the exaggerated surrounding decoration of the front and rear of the car also plays a role in increasing the sense of movement. However, this MARVEL X is more than just watching sports. In order to improve performance and fuel economy, its streamlined shape and optimized low wind resistance rearview mirror, together with the hidden door handle, have reduced it to 0.29Cd.

From April 18 to 27, 2023, the 20th Shanghai International Automobile Industry Exhibition was held in the National Convention and Exhibition Center (Shanghai), showing the new look of technology leading the automobile industry to change in a new era. At the exhibition, China Mobile focused on the ToV market’s "car, road, network, cloud and map" capabilities, showing its core advantages and important achievements in the fields of intelligent networking, intelligent cockpit and intelligent driving, which attracted a lot of attention. With the theme of "Go all out to go out with blood", China Mobile held an expedition ceremony for the car networking corps, and awarded military orders and flags to 14 teams and provinces, marking the official expedition of the car networking corps of China Mobile.

Intelligent networking: building a secure cloud and a powerful network

The intelligent networked system based on secure cloud and powerful network provides basic guarantee for intelligent networked vehicles. Relying on mobile cloud’s ability, China Mobile has realized the "N-31-X" resource layout, provided professional cloud services with integrated cloud and network, and supported the business needs of various scenarios in the automobile industry. "Mobile Cloud creates safe, compliant, stable and reliable cloud infrastructure services and capabilities, builds a car enterprise cloud and an autonomous driving cloud for the whole life cycle of automobiles, and provides unified data and analysis for car companies and autonomous driving R&D enterprises."

Relying on 5G cellular network, high-precision positioning network and vehicle-road collaborative network, China Mobile has realized the basic capabilities of communication and calculation, high-precision positioning and mapping, and integrated perception and information interaction. At the same time, using the edge computing power of 5G, it provides information services for self-driving vehicles of different grades.

A strong network cannot be separated from the support of computing power. Faced with the higher demand for secure and reliable connection and computing power network in the field of intelligent network connection, China Mobile takes advantage of 5G-edge computing to meet the demand of secure and reliable connection and low-delay computing power supply, and builds a highly reliable collaborative computing network application.

Intelligent cockpit: deep integration of infotainment and intelligent service

"Know Your Car" is the highlight of China Mobile’s participation in this exhibition. The information and entertainment sharing product of "People and Car Home" debuted for the first time. Through the capacity base of China Mobile’s OneTraffic platform, it provided four capabilities: unified mall operation, "People and Car Home" integrated operation, ecological aggregation service and refined service operation, which met the needs of car companies such as content services, car owners’ traffic renewal service and car rights subscription.

"This is a car-end product that combines the capabilities of China Mobile’s own products. It applies the unified account capability and self-owned content product capability of China Mobile to the car-end, and creates car owners’ service products through high-frequency usage scenarios such as refueling and traffic recharge." According to the on-site staff, the product can quickly identify the owner’s personal network information through the identification of the Internet of Things card-real name interface; Users can use a small phone bill to pay for the traffic products in the car and get through the consumption behavior of people and cars. The audio and video rights purchased in the car can be shared on the mobile phone.

The Miguyuan Cosmic Intelligent Cockpit is another eye-catching exhibition. China Mobile, through technologies such as 5G﹢AI﹢XR, has joined hands with many car companies to build a Meta-Cosmic Intelligent Cockpit, which provides users with a one-stop entertainment service of "listening, singing, watching and playing".

Intelligent driving: high-precision "map" and intelligent "road" escort safety

China Mobile has deployed and tested indoor Beidou positioning equipment in several tunnels and venues, and achieved seamless outdoor lane-level navigation, accurate navigation in tunnels and continuous indoor and outdoor navigation, which is forming a leading space-time information capability in the industry.

"China Mobile’s joint partner tackled technical problems such as seamless connection and positioning of indoor and outdoor Beidou, and obtained more than 10 patents, creating the first indoor and outdoor continuous high-precision positioning based on Beidou." On-site staff told reporters that China Mobile’s self-developed indoor Beidou base station, terminals and other equipment can regenerate Beidou satellite signals in indoor scenes, which can provide accurate positioning and navigation indoors and provide accurate location services for intelligent driving in tunnels, parking lots and other scenes.

Smart intersection is the junction of smart cars and smart cities, and it is also an important edge node for future vehicle-road coordination. Vehicle-road coordination, scene verification and commercialization of autonomous driving all need to rely on intersections to achieve landing, which is an important node of "facing the future and compatible with the present".

"The smart intersection platform relies on the operator’s edge cloud, 5G and C-V2X converged networking capabilities to gather multi-source sensing data at the intersection and provide low-latency dual-channel information services for vehicles." On-site staff introduced relevant applications to reporters, including security, efficiency improvement, information service and traffic management.

At the Shanghai Auto Show, there were many highlights in the China Mobile Exhibition Area. "In the future, China Mobile will seize the strategic opportunity of building a transportation power, a network power and a digital China, integrate superior resource capabilities such as network, cloud and map, focus on breaking through core technologies, make full efforts to seize strategic highlands, and accelerate to become the first provider of market information services."

　　[Aika car SUV channel original]

　　Roewe RX5′ s monthly sales of 20,000 units can be said to have earned enough profits and eyeballs for SAIC. It must be said that SAIC’s accumulation in styling design in recent years has brought exquisite appearance to RX5, and another group of young people in the same R&D center have also created many topics for RX5 human-computer interaction system with their unique ideas. What kind of world is hidden under such a car that shines brightly?

　　The vehicle we shot this time is Roewe RX5 20T two-wheel drive Internet Smart Edition, equipped with a 1.5L turbocharged engine and a 7-speed dual-clutch gearbox, driven by front wheel drive.

I. Overview of Chassis

　　Similar to the chassis structure of many compact SUVs on the market, RX5 adopts McPherson independent front suspension and E-type multi-link independent rear suspension. The chassis of RX5 has no redundant guard plate to protect the parts, from which we can also see that it focuses on the positioning of urban road conditions. However, through analysis, we can still find that RX5 is worthy of its price and people’s attention in chassis structure and materials.

　　RX5 adopts a frame-type front subframe, which can not only improve the overall strength of the front of the car body, but also make the force on the front of the car body more uniform.

　　RX5′ s two-wheel drive vehicle adopts a rear subframe similar to H-shape, and almost all the connecting rods on the rear suspension apply force to the rear subframe, thus reducing the direct impact of suspension on the vehicle body. The rear subframe of RX5 four-wheel drive vehicle is structurally different from that of two-wheel drive vehicle.

Second, the front suspension analysis

　　RX5′ s McPherson independent front suspension is really nothing too surprising. Indeed, for most cars under 200,000 yuan on the market, it is too ordinary to adopt McPherson front suspension. However, the details of the RX5 front suspension still have its own special features.

　　On the whole, the front suspension adjustment of RX5 tends to be comfortable, and the damping spring can filter out most small vibrations, but for some relatively large vibrations, the response of the spring is a bit stiff. Usually, the relatively large vibration will be directly transmitted to the car, which makes people somewhat unprepared. However, thanks to this adjustment, RX5 has a good performance in controlling roll.

Third, the rear suspension analysis

　　RX5 adopts E-type multi-link independent rear suspension, which is also quite common in the same class. This multi-link suspension adopts a vertical and three horizontal conventional structure, and most of the connecting rods are stamped from steel plates, and there is not much innovation in the arrangement of connecting rods.

　

Although the TOP3 of vehicle sales has become a repair field for Tesla and BYD, don’t forget that there is an old six who has been a big brother for a long time. This is Wuling, which ranked sixth in sales last month. However, this model may encounter a little trouble, which is the long-life version just listed.

Judging from the Pentium Pony Long Life Edition, its biggest change is the introduction of two CTLC models with a cruising range of 222 kilometers, which means that the cruising range has changed from the original maximum of 170 kilometers to 222 kilometers. This is more advantageous than the classic Hongguang MINIEV.

The current pattern is that the two models newly listed by Pentium Pony have a battery life of 222 kilometers, and the prices are 36,900 yuan and 39,900 yuan respectively. The Hongguang MINIEV classic with a battery life of 170 kilometers is still the 2022 enjoyment of 44,800. Of course, Hongguang MINIEV also has a longer battery life, but the starting price has reached 55,800 yuan, and the battery life is also 200 kilometers. If you want to go further, the official guide price of MINIEV GAMEBOY’s fun money and coffee money is almost 70,000 yuan, which is completely different from the Pentium Pony Long Life Edition.

Looking at Hongguang MINIEV from Pentium pony, the idea of Pentium pony is lower threshold and higher cost performance. Pentium pony has set the minimum allocation to early 20 thousand, to be honest, this is already in the bright market to grab the old man’s music. At the beginning, the idea of Hongguang MINIEV was to share a piece of the low-speed electric vehicle market, so as to change the pattern of the old man music market with higher security. Therefore, the more neutral design makes the rich and the poor fondle admiringly.

However, it seems that the Pentium pony is not well understood, and it has a lovely appearance, which is obviously more focused on this part of the young people market with limited consumption. We are going to talk about this topic in the next article.

Of course, the Pentium pony also has many remarkable places. For example, safety, at such a low price, it can provide you with high-strength anti-collision beams, especially those two airbags, which is already a gift. You know, many vans at the same price and Hongguang MINIEV classic models will not give you these. What’s more, Pentium Pony started to produce cars according to the standards of cars. You can laugh at its small wheels and small space, but only if you compare it with whom and how.

After figuring out these problems, you will find that Pentium pony is more worry-free and easier than electric motorcycles. Its seemingly limited battery life can not only meet your daily commuting needs, but also the travel cost per kilometer is only a few cents, which can be said to be cheaper than crowded buses. Because of this, Pentium pony can continuously achieve monthly sales of over 10,000. After the increase in battery life, there is a trend of reducing the dimension of the classic MINIEV. When the scooter market is facing new changes, can the Pentium Pony Long Life Edition surpass Wuling Hongguang MINIEV to become a new market leader?

　 　 16 days after the acquisition plan was rejected, Gree gave up the acquisition of Zhuhai Yinlong. This result is unexpected to many people.

　　Even when rumors were flying, Dong Mingzhu, the chairman of the board, didn’t reveal the idea of "giving up making cars" at all. However, a sudden announcement made Gree "build a car" come to an abrupt end.

　　"Gree’s fundraising plan was previously rejected by minority shareholders at the shareholders’ meeting. Since then, Gree has indicated that it will change the plan, but its source of funds for the acquisition of Zhuhai Yinlong is inconclusive, which makes the acquisition very uncertain. However, this result is still a bit surprising. Gree’s attitude in building a car was very firm before. " The industry believes that.　

　 　On the evening of November 16th,gree electric appliancesThe announcement said that the company decided to stop planning to issue shares to purchase assets.

　　Gree Electric’s acquisition plan for Zhuhai Yinlong has been controversial since its birth. Three months ago, Gree Electric announced the acquisition plan, announcing the acquisition of 100% equity of Zhuhai Yinlong by issuing shares. After the acquisition, Zhuhai Yinlong will become a wholly-owned subsidiary of Gree Electric. However, the acquisition plan was "voted with their feet" by minority shareholders.

　　At the end of October, Gree’s overall plan to acquire Yinlong and raise funds was finally rejected at its extraordinary shareholders meeting. However, Gree did not disclose his willingness to give up the acquisition. Gree Electric issued an announcement, acknowledging that the proposal on the issue of shares to purchase assets was not passed as a whole, and said that it planned to continue to push forward the issue of shares to purchase assets, and reduce or cancel the matching raised funds. At that time, Gree insiders also said in an interview that they would continue the acquisition, but it would take time to adjust the plan.

　　It is reported that the optimized and adjusted plan will be resubmitted to the board of directors and shareholders’ meeting for deliberation, and the announcement date of the resolution of the board of directors will be taken as the benchmark date for issuance pricing.

　　After Gree’s acquisition plan was rejected, there was an episode in which Dong Mingzhu, the chairman of Gree Electric, changed his position at Gree Group level, causing a sensation in the industry. For a time, people in the industry speculated on the reasons why Miss Dong left the group. Some insiders believe that this may be related to Gree Electric’s acquisition of Zhuhai Yinlong.

　　However, judging from the current actions of Gree, "Miss Dong" gave up making cars in a short time.

　　But this does not mean that Gree does not need to find new profit growth points as soon as possible. Looking at Gree Electric’s annual reports in recent years, we can see that in 2015, Gree Electric’s performance continued to grow, and Gree Electric’s revenue and net profit decreased by 29% and 11% respectively, which was the first time that Gree Electric’s performance declined since its listing. In the first half of 2016, the decline in the company’s performance narrowed.

　　At the same time, "Miss Dong" has repeatedly revealed in public that the air-conditioning industry has entered a saturated stage, intelligence will enter a golden age in the next five years, and Gree has entered a diversified era. Today, Miss Dong enters Gree.intelligent automobileThe promotion of the field has been hindered by many obstacles.

　　"This does not mean that Gree will give up the diversified layout, and the smart industry is still Gree’s new layout direction and future profit growth point." Gree insiders said.

　　This may be another beginning for Gree.

　　　Gearbox is an important part of automobile power. Nowadays, various automatic gearboxes can be seen everywhere in the market. Different automatic gearboxes have different performance and quality. What are the disadvantages and advantages of these automatic gearboxes? Here are some common automatic gearboxes for everyone.

　　Automatic gearbox type

　　AT present, there are three common automatic gearboxes: AT (hydraulic automatic gearbox), CVT (continuously variable automatic gearbox) and D (dual clutch gearbox).

　　First, AT— automatic transmission

　　AT is to use a hydraulic torque converter instead of the dry clutch in the traditional manual gearbox to transmit the power of the engine to the planetary gear mechanism, and realize automatic gear shifting through the electronic control system. AT the same time, the AT gearbox is not as many gears as possible. Because the structure of its planetary gear mechanism is very complicated, adding one more gear will greatly improve its structural complexity, gearbox volume and R&D and manufacturing cost. Of course, there is another problem, that is, the more complicated the structure, the lower the mechanical reliability.

　　Advantages of AT automatic gearbox

　　1. AT gearbox is the most widely used gearbox in the market today, and its mature mechanical structure has been developed and carried forward by many manufacturers.

　　2. The traditional hydraulic automatic transmission adopts hydraulic torque converter (or hydraulic coupler, multi-disc clutch, etc.), which can cushion the power impact of the engine and match the mechanical combination of planetary gears with stable performance. The torque it can withstand is also very high.

　　Disadvantages of AT automatic gearbox

　　1. The AT gearbox needs more mechanical parts, which makes the overall weight larger and the manufacturing cost higher than other gearboxes.

　　2. Because the engine power needs to be transmitted to the gear set through the hydraulic torque converter (or multiple clutches, etc.), part of the engine power will be consumed in vain, so compared with the manual gearbox (including CVT gearbox), the AT gearbox will consume more oil.

　　The fixed gear set used in 3AT gearbox makes the vehicle stumble and make noise when shifting gears. Although the shift impact is greatly optimized with the development of technology, the AT gearbox is still not very smooth in theory.

　　Second, DCT— Double clutch automatic gearbox

　　DCT is actually a general term, such as G and powersht, which are all powershift. They are similar. powershift has fast gear shifting, high fuel economy and can bear large torque. Now it has been widely used in the automobile field. Its transmission mechanism is the same as that of the traditional manual gearbox, but because the two groups of clutches operate independently and alternately, it can almost achieve CVT-like power output. This kind of gearbox has two branches: dry dual-clutch gearbox and wet dual-clutch gearbox. The difference is that dry DCT is. The two sets of clutch plates of wet DCT are in a sealed oil tank, which absorbs heat through the transmission oil soaked with clutch plates.

　　Advantages of DCT automatic gearbox

　　1. The transmission efficiency is high, the power loss is small, and the fuel economy is relatively best.

　　2. The shift response is fast, and the shift smoothness is only slightly inferior to CVT.

　　3. Because its transmission structure is the same as that of manual gearbox, it has the highest bearing capacity.
