On May 10, the 8th China Brand Day, the 2024 China Brand Day series of activities, sponsored by the Shanghai Branch of Xinhua News Agency and China Economic Information Service, and co-sponsored by SAIC Innovation Research and Development Institute and SAIC Passenger Vehicle Roewe Brand - "Super Convergence is Super Hybrid" DMH Technology Brand Conference, was held in Shanghai. Jiang Wei, Secretary of the Party Leadership Group of Xinhua News Agency Shanghai Branch and Secretary of the Party Committee of China Economic Information Service Shanghai Headquarters, Zu Yijie, Vice President and Chief Engineer of SAIC Group, Wang Jun, General Manager of SAIC Passenger Car Company, Lian Ping, Chairman of China Chief Economist Forum, Yao Chunde, Professor of Tianjin University and Deputy Director of the "China Heart" Top Ten Engine Judges, and other guests attended the conference to explore the new breakthroughs in China's hybrid technology and how the new energy vehicle industry can accelerate the cultivation of new quality productivity.
From following to leading, the technological innovation of Chinese automobiles in the huge market scale and fierce competition environment has begun to "feed" the world, and with the leading development of new technologies, new technology brands with global influence will also be born. At the meeting, SAIC Roewe released the "DMH Super Hybrid Technology" technology brand, giving full play to SAIC's deep technical accumulation in the field of hybrid for more than ten years, creating hybrid products for global users, becoming a new kinetic energy that will lead China's hybrid technology to surpass Japanese hybrids in the future, and let the world see the vigorous power of Chinese auto brands in the new energy era.
The leading plug-in hybrid technology can only be done well by Chinese car companies
In May 2014, when General Secretary Xi Jinping inspected the SAIC Passenger Vehicle Technology Center, he emphasized that "the development of new energy vehicles is the only way for the mainland to move from a large automobile country to an automobile power". Over the past ten years, Chinese automakers have fully understood the instructions of the general secretary, increased research and development efforts in the field of new energy vehicles, and adhered to multiple technical paths for continuous innovation. By the end of 2023, China's new energy vehicle production and sales ranked first in the world for nine consecutive years, and became the world's largest vehicle exporter for the first time, and Chinese dominated an emerging industrial field for the first time with innovative technology.
Under the wave of new energy, plug-in hybrid is an indispensable key starting point, whether from the perspective of solving the pain points of users' actual car use, or from the height of the transformation and upgrading of the entire automotive industry chain. Professor Yao Chunde believes that the development of plug-in hybrid technology is the trend of the times, and it is also the only way for Chinese automobiles to lead the world. The leading plug-in hybrid technology can only be done well by Chinese car companies.

On the one hand, plug-in hybrid technology is strongly driven by user demand in China. The U.S. market is accustomed to large-displacement engines and has no R&D power; The Japanese market is eyeing HEVs and hydrogen; Due to the small size of the country and the narrow streets of the city in the European market, the pain points of users for battery life and energy supplement are not prominent, and there is a lack of rigid demand for plug-in hybrid products. China's market environment and user needs provide a natural "fertile soil" for car companies to develop plug-in hybrid technology.
More importantly, the breakthrough of Chinese car companies in plug-in hybrid technology is not to show off their skills, but to be based on real use scenarios, integrating the advantages of traditional fuel vehicles and electric vehicles, and bringing users a real optimal solution for travel. Professor Yao Chunde took the DMH super hybrid system as an example, and innovatively improved the off-axial P1 motor to a coaxial structure for the current mainstream P1+P3 hybrid configuration, which greatly improved the transmission efficiency and optimized the NVH performance, making the whole system more efficient and the driving experience smoother and quieter. It can be seen that plug-in hybrid technology is not a transitional technology, but a key technology to drive traditional vehicles to achieve electrification transformation and comprehensively improve the user's travel experience, and it is an indispensable technical support for China's automobiles to "change from big to strong".
Roewe DMH: Super fusion is super hybrid
"At present, hybrid technology is blooming, products are emerging in an endless stream, and user acceptance is getting higher and higher, and some data predicts that by 2025, pure electric and plug-in hybrid will appear 1:1 situation. The spring of plug-in hybrids is already around us. Lu Yong, deputy general manager of SAIC Passenger Car Company, executive vice president of SAIC Innovation Research and Development Institute and executive deputy director of the technology center, said.

The greatest advantage of any technology with long-term value is that it can withstand precipitation and can carry long-term optimization iterations. As early as 2010, SAIC Motor made a forward-looking layout in the field of plug-in hybrid technology, and regarded it as a technology worthy of long-term investment. In 2017, SAIC's self-developed first-generation EDU hybrid technology won the second prize of the National Science and Technology Progress Award, which was not only the only automotive project among the award-winning projects that year, but also the first time that the new energy technology won the national science and technology award. Thanks to SAIC's in-depth self-research on the core technology of the powertrain, SAIC will also exceed 46% in terms of engine thermal efficiency, a key indicator that affects the performance of the hybrid system. After long-term technology accumulation and market verification, the DMH super hybrid technology released at this conference has reached a higher level of integration and intelligence, which is a new driving force for SAIC's own brands to maintain long-term competitiveness.
DMH super hybrid technology has three technical characteristics: modularization, integration and exclusivity. At the same time, the system has the industry's first "energy domain" global thermal management, powertrain brain PICU, engine + P1 motor coaxial structure and other leading technologies, with software algorithms as the core, matching special high-efficiency engines, gearboxes, long-range batteries and other special hardware for hybrids, "both soft and hard". Achieve hyper-convergence to achieve the highest performance and optimal indicators.
At present, DMH super hybrid technology has been first installed in the "long-range super-hybrid cloud-sensing car" Roewe D7 DMH, and the "long-range new mainstream hybrid SUV" Roewe D5X DMH, and the product strength has been widely recognized by users and professional media. Not long ago, the Roewe D7 DMH challenged the 2000km limit range on behalf of its own brand B-class car, and finally overcame the impact of bad weather to complete the ultra-long range of 1962km and the average fuel consumption of 2.8L per 100km, realizing the transformation of technical value from technical strength to scene application, showing the strength of Chinese brands to break through the "endurance myth" of Japanese hybrids.

Qiu Jie, vice president of SAIC Innovation Research and Development Institute and general manager of Jieneng Automobile Co., Ltd., said that in the next three years, the DMH super hybrid technology brand will carry out higher-dimensional performance improvement in five key areas: engine, gearbox, battery, motor, and energy control brain. For example, the thermal efficiency of the engine will break through to 46%, and take the lead in China to meet the "Euro VII" emission standard; In terms of transmission technology, the target CO2 emissions of the diesel-electric hybrid route will not exceed 95 g/km, and the plug-in hybrid and extended-range electric routes will adopt a new configuration of dual coaxial scheme; The energy control brain continues to be optimized, and the next-generation vehicle energy center concept is expected to be released in 2025.
Launching the SAIC brand to help Chinese automobiles "grow from big to strong"
Brand economy is a comprehensive embodiment of national competitiveness; Brand influence is related to the country's position in the global industrial chain value chain. After the improvement of market scale and product quality, China's new energy vehicles have come to a new stage of expanding brand influence.
Zu Bijie said at the conference: "Brand building is an important support for the further development of the mainland's intelligent networked new energy vehicle industry. At present, SAIC is benchmarking the construction of a world-class enterprise, making every effort to build a trillion-level automobile industry group with global competitiveness in the industry and international influence of the brand, and continuously building the SAIC brand by building SAIC with science and technology, quality SAIC, and responsibility SAIC. The launch of DMH super hybrid technology is the 'super integration' of science and technology SAIC, quality SAIC, and responsible SAIC, and it is also an important practice to launch the SAIC brand. ”

For a long time, SAIC has adhered to technological innovation as the core driver, accurately grasped the market development trend, and actively laid out forward-looking technology fields. After long-term unremitting investment and deep cultivation, the "turnaround" from technology introduction to technology reverse output has been basically completed. In the face of a new round of global competition, SAIC Motor's self-owned brand vehicle R&D platform, SAIC Innovation R&D Institute, has made full preparations in the fields of forward-looking technology, R&D personnel, hardware equipment, etc., and has efficiently supported the product development of the four major brands of Roewe, MG, Zhiji and Feifan and overseas markets.
In terms of talent pool, SAIC Innovation R&D Institute is committed to building a R&D team with global vision and competitiveness. Not long ago, Mr. Joseph Carban, a world-renowned car designer, the founder of the Bugatti Veyron supercar, and the former chief designer of Audi exterior, officially joined SAIC, which will further promote the upward upgrading of SAIC Design, vigorously enhance the competitiveness and internationalization level of SAIC Design, and empower SAIC's Roewe and other independent brands.
The release of the DMH super hybrid technology brand marks that SAIC Roewe will start the quality and value war of its own brand "national team" in the homogeneous new energy market with a more confident brand image and stronger product competitiveness, and help China's new energy vehicle industry develop towards high quality and high level. In the future, relying on the DMH super hybrid technology brand, Roewe will also gather superior resources from all parties to accelerate the creation of the "first camp of plug-in hybrids" and provide global users with new hybrid options for Chinese brands.
