Recently, the "Heart of China" 2021 Top Ten New Energy Vehicle Power System was unveiled in Beijing. After the selection of industry experts and media judges, BYD DM-i super hybrid drive system won the "Heart of China" 2021 Top Ten New Energy Power System Award, and the models currently equipped with this system are Qin PLUS DM-i, Song PLUS DM-i, Song Pro DM-i, Song MAX DM-i and Destroyer 05, of which Qin PLUS DM-i appeared on the list as a recommended model.
Won the "Heart of China" 2021 Top Ten New Energy Power System Award
According to reports, the "China Heart" annual top ten new energy vehicle power system selection, sponsored by the Automobile and Sports Magazine, has been held for six sessions so far. The various powertrains shortlisted this time cover almost the entire new energy vehicle market. BYD's DM-i Super Hybrid Drive System won this award after preliminary review, technical exchange meeting, on-site real vehicle testing and other links.

It is worth mentioning that among the powertrains shortlisted this time, THE BYD DM-i Super Hybrid is the only system installed on many mass-produced models. The jury passed the inspection and inspection of vehicle power, energy consumption, driving experience, NVH and other aspects. BYD's DM-i super hybrid system creatively defines the "electricity-based" hybrid technology, which is an electric hybrid architecture around high-power motor drive, large-capacity power battery power supply, and engine as a supplement, subverting the traditional hybrid "oil-based" design.

The DM-i Super Hybrid Drive System consists of three core components. The 1.5L high-efficiency engine has the world's leading thermal efficiency of 43.04%, 15.5:1 ultra-high compression ratio, and adopts industry-leading technology of Atkinson cycle, cooling EGR, split cooling, ultra-low friction, and wheelless train design. The maximum speed of the motor of the EHS electromissible system is 16000rpm; the maximum efficiency of the flat line motor is 97.5%, and the high efficiency zone accounts for 90.3% (the high efficiency zone refers to the efficiency of more than 90%), reaching the industry-leading level.
DM-i super hybrid special power blade battery, with lithium iron phosphate thermal stability and blade structure design, passed all kinds of strict safety tests; at the same time, lithium iron phosphate stable material crystal structure and thermal management system, to ensure the long life of the blade battery, to create a super safe and long life of the power battery.
Models equipped with dm-i Super Hybrid truly achieve ultra-low fuel consumption, quiet and smooth, and excellent power performance. Under NEDC conditions, the power loss and fuel consumption are only 3.8L/100km. At the same time, it can be oiled and electric, and the comprehensive driving range is as high as 1245km, providing an infinite driving experience that is close to pure electricity. In addition, it also has a strong power of 7.3s acceleration per 100 kilometers, far exceeding the 2.0T fuel vehicles of the same class.
