On May 28th, the historic city of Xi'an welcomed the grand launch of BYD's fifth-generation DM technology and its all-new models, the Qin L DM-i and the Seal 06 DM-i.

This technological breakthrough, featuring the world's highest engine thermal efficiency of 46.06%, the world's lowest fuel consumption of 2.9L per 100 kilometers in electric-deficit mode, and the longest comprehensive range of 2100 kilometers, has not only rewritten the history of automotive fuel consumption but also ushered in a new era of fuel efficiency, setting a new global benchmark for plug-in hybrid technology.

At the new car launch event, BYD founder Wang Chuanfu proudly stated: "The global plug-in hybrid market has entered the Chinese moment!"

I. The global fuel consumption history is rewritten, setting a new benchmark for plug-in hybrid technology.

According to data statistics, in 2023, the sales volume of plug-in hybrid models in China increased by 85% year-on-year. Globally, for every 4 plug-in hybrid models sold, 3 are Chinese brands. In China, for every 2 plug-in hybrids sold, one is a BYD.

BYD has always been leading the mainstream position of China's automotive industry in the global automotive technology development with its strength and innovation.

At this launch event, BYD unveiled a total of 5 versions of the Qin L DM-i and Seal 06 DM-i, priced between 99,800 and 139,800 yuan. From a positioning perspective, these 5 models can be compared with mid-to-low-end sedans and MPVs. Among them, the higher-priced Seal 06 DM-i competes with pure electric models in the 200,000 yuan category.

Compared to previous products, the new cars released this time have undergone comprehensive upgrades, such as the use of higher-quality materials for exterior and interior design, larger dimensions, and stronger power, while also achieving faster acceleration, lower fuel consumption in electric-deficit mode, and longer maximum comprehensive range.

Furthermore, thanks to the adoption of the fifth-generation DM technology, consumers no longer have to worry about fuel consumption, electricity consumption, and price when making choices. A BYD hybrid car not only achieves lower energy consumption but also comes with the most competitive price in the entire market, truly making consumers feel from the heart: affordable and cost-effective.

Why is the BYD series equipped with the fifth-generation DM hybrid technology so competitive? This has to start with the technical architecture of the fifth-generation DM hybrid technology.II. What is the technical architecture of the fifth-generation DM hybrid technology?

The fifth-generation DM hybrid is hailed as the world's leading technical architecture, mainly reflected in these three aspects:

1. It is an electricity-centric power architecture, characterized by high power, high torque, high energy efficiency, and low energy consumption.

2. It features a full-temperature range vehicle thermal management architecture, which allows the vehicle to achieve optimal heat dissipation and heating in various extreme weather conditions.

3. It has an intelligent electrical fusion electronic and electrical architecture, which simplifies the number of components, increases response speed, and makes the operation of hybrid vehicles more simple and user-friendly.

The combination of these architectures provides the vehicle with outstanding performance characterized by "fast, economical, quiet, smooth, and green."

At the same time, the fifth-generation DM hybrid employs three key inventions to solve one of the most troublesome issues for consumers—high energy consumption. It is well known that the internal combustion engine is one of the most important components in a hybrid vehicle, and the level of its thermal efficiency determines the fuel consumption performance of the vehicle. BYD's self-developed ECVT (Electronic Continuously Variable Transmission) and high-efficiency water-cooled components have addressed the challenge, achieving an engine thermal efficiency of 46.06%!

Additionally, BYD's EHS (Electric Hybrid System) has increased power density by 70.28% through its ultimate structural design, while significantly reducing losses in the energy flow path, achieving a comprehensive working condition efficiency of 92%. The dedicated blade battery has increased its energy density by 15.9%, providing ample "blood" for the vehicle's "heart."

Furthermore, by integrating the VCU (Voltage Control Unit) and dual MCU (Motor Control Unit), the chip's computing power has been increased by 146%, improving response speed, greatly enhancing the vehicle's integration and performance, while also saving energy consumption.Triple technological architecture enhancement reduces vehicle fuel and electricity consumption to the industry's top level, fully meeting consumers' demands for "low energy consumption with both fuel and electricity open".

III. Why can BYD's hybrid technology take the lead?

Since BYD's fifth-generation DM technology is so excellent, why haven't domestic manufacturers, who have been relatively unknown before, learned from it? This is because many previous "domestic" hybrids were actually from foreign joint ventures.

Of course, in order to overtake on the inside, various car companies have also introduced general hybrid technologies. However, due to the complexity of the technology and the difficulty of implementation, they eventually failed. In contrast, BYD, after 30 years of trials and tribulations, has finally developed its own fifth-generation DM hybrid technology, which will completely change the current situation of China's hybrid technology relying on foreign technology.

So why can BYD independently develop the world's top technology in the field of plug-in hybrid vehicles?

This is because, as the only domestic new energy vehicle manufacturer that masters the core technology of the entire industry chain, BYD has world-class R&D strength and unmatched production capacity.

Moreover, BYD has seized two historical opportunities:

First, the national support for the development of independent new energy;

Second, the high demand for energy storage devices in clean energy industries such as photovoltaics and wind power.

When the market and policy opportunities come, the two together have created BYD's "god-like" path.IV. Conclusion

Nowadays, plug-in hybrid vehicles have entered a phase of widespread adoption, with many families in second and third-tier cities considering hybrid models as their top choice for purchasing a car. This trend reflects, on one hand, the steady enhancement of domestic consumers' economic strength, and on the other hand, it indicates that the concepts of environmental protection and energy consumption are becoming deeply ingrained in people's minds.

In this context, the emergence of BYD's fifth-generation DM hybrid technology signifies that Chinese automotive brands are gradually leading the way for people to move away from an over-reliance on fossil fuels. After all, every inch of land and every river beneath our feet requires our careful care and protection!
