If there is a big surprise in the auto market last year, it is that several models equipped with BYD's DM-I hybrid system have been launched. In the current model has been greatly enriched, pure buyer market situation, BYD DM-I model but there is a situation of waiting for the car for a very long time, it is said that some car owners waited for 6 months to mention the car, and in the model complaint reasons, waiting for the car too long impressively ranked first. Such a situation has really not been seen for too long, which fully illustrates the current heat of BYD DM-I in the market.
Driven by BYD's DM-I model, BYD achieved vehicle sales of 730093 vehicles last year, an increase of 75.4% over 2020. The best-selling Qin plus DM-I achieved a total of 194,220 vehicle sales in the whole year, with 25,943 units sold in December 2021 alone. This sales volume for domestic cars, is already a very top performance, and limited by production capacity, it still has considerable room for improvement.
So, what is a BYD DM-I hybrid system? Why can it kill all sides with this technology?
More than ten years of research and development DM-I has achieved great success
In fact, BYD has been studying the hybrid system for a long time, as early as 2008 launched the first generation of hybrid models, becoming the world's first plug-in hybrid electric vehicle, in the following years, Song DM, Tang DM and other models despite the performance is very good, but due to the high price, resulting in a situation of bad seats.
With BYD's more in-depth research on hybrid systems and the birth of safe and efficient blade batteries, the DM-I super hybrid system finally came into being. It contains core components such as 1.5L plug-in hybrid special Snapdragon engine, EHS electric hybrid system, special power blade battery, AC and DC vehicle charger and so on. The entire system, whether it is the engine, power battery, control system, management system, etc., is 100% independently developed by BYD, which can be described as the culmination of BYD's hybrid technology.
The two most important core components of the DM-I Super Hybrid System are the plug-in hybrid 1.5L engine and the blade battery. The engine adopts advanced technologies such as Atkinson cycle, EGR exhaust gas recirculation, split cooling thermal management, electric water pump, etc., the compression ratio can reach 15.5:1, the highest thermal efficiency reaches 43.03%, and the overall performance performance reaches the highest level in the industry. Moreover, the blade battery equipped with the DM-I Super Hybrid System is specially produced for hybrid systems, which is second to none in the industry in terms of safety and efficient use of electricity.
From a technical point of view, DM-I super hybrid is an electric,oil-supplemented power system, with EV pure electric mode, HEV series mode, HEV parallel mode, engine direct drive mode and other four driving modes, usually mainly rely on the motor to drive the wheels, only in the case of high-speed driving, the engine will intervene in the drive wheels, in parallel direct drive, to achieve efficient engine driving. When the power is sufficient, the DM-I super hybrid engine is basically not involved, the driving experience is very close to the pure electric car, and when the power is insufficient, it is an ultra-low fuel consumption hybrid. With the DM-I super hybrid system, BYD has truly achieved more electricity, less oil and efficient oil use.
Practical and affordable, DM-I is a huge hit
Unlike the PERFORMANCE-oriented DM-P models, BYD DM-I models pay more attention to achieving a good balance between performance and fuel consumption. Taking the popular Qinplus DM-I as an example, its power loss fuel consumption is as low as 3.8L/100 km/ 100 km/ 100 km/ 100 km/h, but it has reached a good performance of 7.3 seconds, whether it is fuel consumption or performance performance, there is basically no opponent in more than 100,000 models. The maximum endurance of more than 1,000 kilometers and the green card policy have made Qin plus DM-I perfectly cut to the current public's anxiety about the endurance of pure trams and the pain points of charging difficulties, and at the same time have an almost pure tram driving experience.
Moreover, the price of Qin plus DM-I is also very close to the people, the price of 107,800 to 147,800, compared with the same level of domestic models, only 10,000-20,000 yuan more expensive, compared to the same level of joint venture models, and cheaper tens of thousands. Moreover, the Song Pro DM-I and Song Plus DM-I, Tang DM-I and other models on sale are also the same, only need to spend an extra 10,000 or 20,000 yuan, you can have a very low fuel consumption, the power is still very strong family car, it is no wonder it will usher in a crowd of people to rush the situation. It can be said that the current market sales of BYD DM-I models are only limited to its output, and as much as it can produce, it can sell as much as it can sell.
In general, the DM-I super hybrid system is not only technologically advanced and affordable, which is an important reason why it is difficult to find competitors in the market. Judging from the current market situation, if the hybrid models of competitors do not keep up quickly, the best-selling scene of BYD DM-I super hybrid will continue.
