In addition, Roewe brand also announced that Roewe’s "D Family" will carry out innovative cooperation with the big IP "Chang ‘an Three Wan Li", and select "Gao Shi", which is well-known in the history of ancient China literature and popular in Chang ‘an Three Wan Li, as an endorsement for Roewe D7 users.?
Technology leadership, unlisted has won awards.
At present, a new wave of price reduction in the automobile industry has been opened, and the market competition is more intense. "For SAIC, we have to pressurize ourselves and speed up the transition to a new track." Two days before Roewe D7 went public, Zu Sijie, vice president, chief engineer and president of Innovation Research and Development Institute of SAIC, told the media that in the next two years, SAIC will accelerate the launch of ten hybrid vehicle products, including cars, SUVs, MPVs and other models, to meet the needs of different market segments, different countries and regions, and to empower SAIC’s three-year action plan for the development of new energy vehicles.
Roewe D7 is the "vanguard" of this series of new products.
"After the test drive of the Roewe D7, I feel that this car is like a’ suitable man’ in a new energy vehicle, featuring a reality." Professional car critics give high-quality evaluation. Since Roewe D7 opened the pre-sale, the market response has been enthusiastic. On the technical side, Roewe D7 is equally strong, and has won several industry authoritative awards with its core technology.Not long ago, the results of the "2023 Hybrid Vehicle Extreme Challenge" were announced. Roewe D7 DMH beat BYD Han DM-i, Accord PHEV and other models in the same group with outstanding performance and won the first place in the medium and large car group. At the same time, in the fuel consumption test, Roewe D7 DMH won the championship of all models (including BYD Qin Plus DM-i, Geely Yinhe L6, etc.) with ultra-low fuel consumption of 4.61L/100km.
In the just-concluded "China Heart" 2023 Top Ten Engine and Hybrid System Selection, Roewe D7
With excellent technical strength and excellent performance, DMH stands out from the powertrain of 15 cars, including Changan Ford, BMW Brilliance and FAW Hongqi, and won the honorary title of "Top Ten Engines and Hybrid Systems".

In the crazy "involution" of new energy vehicle technology, in 2023, the automobile industry ushered in the accelerated transformation of intelligent electrification. Both traditional car companies and new car-making forces are competing for the right to speak in the market with stronger strength and lower prices. The Roewe D7 listed this time has "rolled up" new strength in the new energy vehicle market.
"In order to ensure the stability of the DMH super hybrid system, we drove the test car across the Heihe River at-38 C and Turpan, where the surface temperature reached 58 C. It can withstand the test whether it is cold or high temperature." Qiu Jie, vice president of SAIC Innovation Research and Development Institute, gave a set of data: the durability verification of DMH super hybrid system reached more than 100,000 hours, and the vehicle road durability test exceeded 10 million kilometers; At the same time, the design life of the hybrid gearbox has exceeded 1 million kilometers, and the engine has experienced millions of full throttle start-stop and extreme temperature shock tests from -30℃ to 117℃, ensuring the design life of the engine for 10 years/240,000 kilometers.
"Compared with BYD Qin PLUS DM-i gearbox, SAIC’s intelligent and efficient hybrid gearbox is smaller and lighter, but its output power and integration are higher, and its mechanical transmission efficiency reaches 98.5%. Just like the evolution of electronic products, mobile phones are getting thinner and lighter, but their performance is improving rapidly. " Qiu Jie said.
Initiate "five in one"
Focus on the mainstream family car market
How can we truly take users as the center and make electrification the lowest cost and the best performance?
"Energy domain" is a new concept first put forward by SAIC Roewe in the industry. What is the "energy domain"? During the research and development of the new generation hybrid system, SAIC technical team creatively developed a highly integrated powertrain brain PICU. The five-in-one functions of motor control, engine control, hybrid gearbox control, air conditioning thermal management and battery thermal management can be realized through the powertrain brain PICU, so as to realize "variable sharing" by "domain".
This innovative method saves 70% redundant components in vehicle manufacturing, reduces the network load and data delay in the vehicle, and improves the operation speed by 50%.
"Faster, you can bring us more imagination." Qiu Jie said that thanks to the powertrain brain PICU, the Roewe D7 DMH’s dynamic response time is only 0.26 seconds, which is twice as fast as competing products at the same level. Speed-up and overtaking are "one step ahead".
Not only is it faster, but the fuel consumption level of the new generation of DMH super hybrid system is significantly better than the existing competing products in terms of economy. Taking Roewe D7 as an example, after actual measurement, compared with competing products at the same level, it saves fuel by nearly 10%; At the same time, due to the reduction of the heat load of the hybrid engine, the user’s maintenance and use cost are reduced by more than 10%.
In this melee, some brands pursue deep binding with labels such as young trends and smart driving, and some brands choose to exert their strength upwards, and the sword refers to the high-end new energy car track. Roewe, the first company in the industry to propose and mass-produce "Internet cars", is still deeply involved in the mainstream family car market.
Insist that users spend the least money and run the farthest. Relying on the DMH super hybrid system, Roewe D7 is equipped with a special high-efficiency long-life battery and a 1.5L hybrid engine. The comprehensive cruising range of CLTC can reach 1400km, which can meet the needs of the whole scene. At the same time, Roewe D7 brings a more fuel-efficient experience with 43% thermal efficiency.
In addition, Roewe D7 EV is equipped with two Rubik’s Cube batteries with different power levels, and the CLTC cruising range can reach 510km and 610km respectively, which is enough to meet the daily commuting needs.
A "qualified" family car needs a sense of quality, comfort and technology on the basis of competition technology and use cost.
In appearance, Roewe D7 has a wheelbase of 2810mm and a body size of 4890*1890*1510mm. Sitting in the car, Roewe D7′ s innovative "Yunsu Intelligent Cockpit", especially the main driver’s seat, can realize "one-button big lying" and change into a 1.7-meter cot every second. In the central control part, Roewe D7 is equipped with a 12.3-inch super-long LCD central control large screen, equipped with a brand-new zebra intelligent driving machine system, which combines the functions of multi-language and multi-meaning, and creates a futuristic car experience.
For the vast majority of ordinary consumers, they can still achieve an "intelligent and efficient" travel experience without paying very expensive costs. Liu Jing ‘an, senior product director of Roewe Brand Division of SAIC Passenger Cars, said: "In the past, car companies that developed hybrid technology paid more attention to data than actual usage scenarios and user needs. Nowadays, the emergence of Roewe DMH super hybrid system pays more attention to the real needs of users, and is committed to transforming the value of hybrid technology into user value, so that China people can go from’ saving buying’ to’ buying value’. "
After more than ten years of technology accumulation, Roewe has accumulated a lot.
Without accumulating each short step, one cannot cover a thousand miles.
In recent years, the strong desire to win market recognition and meet users’ needs has enabled China automobile brands to grasp every detail and strive to achieve every breakthrough.
"SAIC is one of the earliest vehicle manufacturers in China to realize self-research and mass production of powertrain systems such as engines and gearboxes. The blue core series products have won numerous awards for engines and gearboxes at home and abroad." Zu Sijie said that since the launch of the first Roewe 750 Hybird model in 2010, SAIC has been deeply involved in the hybrid system for more than ten years, and has sold nearly 500,000 hybrid vehicles. It has successively launched Roewe e550, Roewe e950, Roewe eRX5, MG eHS and other plug-in hybrid vehicle products that sell well at home and abroad.
In 2017, SAIC’s "Key Technology and Industrialization of Low Energy Consumption Plug-in Hybrid Passenger Cars" project won the "Second Prize of National Science and Technology Progress Award", which was not only the only automobile project among the award-winning projects in that year, but also the new energy vehicle technology won the national science and technology award for the first time. In addition, the project of "Key Technology Research and Industrialization Application of SAIC Plug-in Hybrid" and the project of "Independent R&D and Industrialization of Roewe e550 Plug-in Hybrid Car" won the first prize of China Automotive Industry Science and Technology Award and the first prize of Shanghai Science and Technology Progress Award respectively.
Since 2021, no matter from the perspective of market scale, user experience or technological development, both plug-in hybrid and extended-range hybrid have ushered in a new stage of development: hybrid products have changed from a vehicle platform based on "oil to electricity" to a product stage with the goal of reducing fuel consumption, to a vehicle platform based on "electricity to hybrid" and a super hybrid product stage that pays more attention to user experience.
Facing the profound changes in the automobile industry, on the basis of more than ten years of mixed research and development, with the acceleration of the "Three-year Action Plan for the Development of SAIC New Energy Vehicles", SAIC Roewe has launched a new round of "Xiangxin", and plans to launch eight new energy vehicles in the next three years, and actively create independent brands, distinctive advantages and explosive products with distinctive identification and technological leadership.
