After the meeting, Lu Yong, executive vice president of SAIC Motor's Innovation Research and Development Institute, Qiu Jie, deputy director and deputy chief engineer of SAIC's Innovation Research and Development Institute, and Park Chunxu, chief marketing officer of SAIC Passenger Vehicles, accepted exclusive interviews with the media and told us It elaborates on the technical advantages of Roewe DMH and its views on "going global with technology" in more detail.

Interviewed leaders:

· Lu Yong, Executive Vice President of SAIC Group Innovation and R&D Institute

· Qiu Jie, Vice President and Deputy Chief Engineer of SAIC Innovation Research and Development Institute

· Park Chunxu, Chief Marketing Officer of SAIC Passenger Vehicle Company

Question: Plug-in hybrids and extended range are very popular right now, and everyone is talking about the extremely high thermal efficiency. Where is our competitiveness reflected? If you go overseas, is there a market for this kind of technical route overseas?

Qiu Jie: The first is the issue of thermal efficiency, and the second is the issue of going to sea.

Regarding the issue of thermal efficiency, I mentioned in my report that we not only undertake independent development, but also undertake national scientific and technological tasks. Among the projects supervised by the National 14th Five-Year Plan, the only thermal efficiency project for automobile brands is carried out by SAIC. The thermal efficiency target of this project is greater than 45%. Last week, under the on-site supervision of the national certification agency, we completed vehicle testing and certification, and the thermal efficiency has exceeded 46%. There are data and reports for this. You can check it. It is easier to speak with facts.

The answer to the question about going to sea is relatively simple, because the facts prove everything. At present, the EP2 and ES3 new MG3 hybrids have been announced in Europe. The target value is 100g, and the actual measured value is 98.12g. In terms of thermal efficiency itself, the authenticity is most clearly reflected in the carbon dioxide data. Therefore, I think it has been relatively clear what the competition between overseas and us is. From an echelon perspective, we are currently relatively close to Japan and South Korea, both in the area below 100g.

Q: What is the current level of SAIC’s technology research and development capabilities? How does its strength compare with BYD?

Lu Yong: If I could answer in one sentence, it would be "internationally advanced level".

BYD has its own strengths and advantages. Currently, on the new energy track, the entire Chinese automobile industry has grown from big to strong. I deeply feel that the new energy track may be a real opportunity for the Chinese automobile industry to grow from big to strong. track.

On the new energy track, both SAIC and BYD have given full play to their respective advantages and taken advantage of this opportunity to truly develop the Chinese automobile industry. I was born in the best era. From technology introduction, joint venture learning to independent innovation, it is indeed a stage that I can strive to surpass on the new energy track.

The new energy track is large enough to allow many Chinese companies to join forces to compete with Tesla in technology and market together. Now it is clear that on the new energy track, not only Chinese companies, but also foreign companies like Germany are following, and they are also unswervingly moving in this direction. It would be great if SAIC and BYD could use this opportunity to become stronger together.（xingaonai）

Question: Talking about the latest product Roewe D5X DMH launched, the current pre-sale price is 119,800 yuan. With the powerful technology of DMH super hybrid system, this product is compared with competing products, especially Song PLUS DM-i , what are the advantages? How will the technical and product advantages be disseminated and promoted in the future?

Park Chunxu: Regarding the positioning of Roewe D5X DMH, we first learned from it and found the most successful partner in this market segment, Song PLUS DM-i, to comprehensively benchmark in size, space, configuration, and safety:

First, in terms of power, the Roewe D5X DMH uses a 1.5T hybrid-specific engine, which provides higher power attributes, better climbing ability, passability, etc. The 1.5T Roewe D5X DMH can achieve two performances: 6.9s acceleration time to 100 kilometers and a top speed of 200km/h.

Second, we chose the largest battery in its class, 21.4kWh. Two performance results are formed: one is that the pure electric cruising range is longer, reaching 135km, and our learning target is 110km; the second is that it is equipped with a 6kW external discharge, which can satisfy outdoor travel, wild camping and other scenarios. This is also the case. Level maximum power external discharge to meet more electrical needs.

Third, we spare no effort in investing in safety. The proportion of high-strength steel used in the entire vehicle reaches 79%. In fact, in the industry, using 60% or 70% high-strength steel can achieve a safety level that everyone can feel, but we used 79%. In addition, the proportion of ultra-high-strength steel used reaches 44%; our side air curtains are 1.2 times that of competing products and maintain 60% of the pressure 6 seconds after impact, which can provide consumers with the greatest safety protection capability at the most critical moment.

Fourth, in terms of quality materials, we use suede materials that are only equipped in luxury cars in places within reach, giving customers a warm and elegant riding experience. There are also things you can’t see. For example, we provide the most comfortable seats in its class, which are reflected in the length of the seat cushion and the thickness of the sponge filling. I believe these investments are worth it.

Fifth, regarding smart driving and smart cabins, the 135 Technology Edition provides an L2-level smart driving system. In terms of smart cabins, we support voice interaction functions that can mean everything in one sentence. We have added a lot of costs in aspects that may not be immediately felt by customers. We firmly believe that these costs will receive positive feedback from the market and users.

Lu Yong: I just mentioned "safety, comfort, energy saving and environmental protection". Chinese users are very concerned about automobile NVH. When we designed and developed this car, we had relatively high requirements in this regard. When you sit in a car, close the door, and roll up the glass, you can feel the isolation from the outside world. The voices of people outside will appear less clear. This sense of isolation is the effect we pursue for NVH.

Some cars are quite different from new cars after two or three years of use. And we invest a lot of energy in long-term reliability and consistency, which are our requirements for quality, NVH, long-term durability and attenuation.

Q: Currently, in terms of technical cooperation, the main focus is on platforms and car bodies. So what areas will technical cooperation expand to in the future? Does it include smart driving and smart cabins?

Lu Yong: As a key area of technical cooperation, the lower body basically covers core technical elements such as battery, electric drive, control, chassis, etc. All the things that we think are the most decisive elements in vehicle technology are all in it. This is called the platform. However, our technical cooperation is not limited to this, and also includes other aspects, such as intelligent network technology.

The Germans believe that the development of China's automotive technology is based on catching up with them and integrating China's advanced digital technology. Mobile phones, digital payments, etc. are all digital technologies. Although there are differences between China's digital technology and Germany's, China's digitalization level cannot be said to be completely leading, but it is certainly higher. These digital technologies must have brought great convenience to people. Safety and comfort, at least in terms of comfort, bring great convenience, so we will provide corresponding output or cooperate with them in these aspects.

In terms of smart driving, Tesla’s smart driving technology is indeed quite good. In addition, China's smart driving technology is also excellent, especially in the application of images, radar, digital processing, etc. Computer technology is mainly responsible for digital processing of images and video streams. Therefore, smart driving and smart cabins are key areas of our cooperation.
