ACCORDING TOD's official data, BYD terminal sales in 2021 will be 730093 vehicles, an increase of 75.4% over last year. Among them, BYD's best-selling model is the Qin plus dm-i, which sold 194,220 vehicles throughout the year and 25,943 units in December alone.
As a has been deeply rooted in the field of pure electricity and plug and mix, BYD has made such a brilliant achievement is natural, but this does not mean that other independent brands are not competitive in this field, on the contrary, with the release of their own hybrid systems by various car companies, the current competition in the domestic hybrid market is more intense.
On April 26, Geely Emgrand L Thor Hi · X is officially listed, as a subsidy after the price of 129,800 yuan - 145,800 yuan of compact plug-in hybrid sedan, then its main competitors locked in BYD Qin PLUS DM-i. As two powerful players in the independent brand, who can be better in the case of the same equipped with their own latest hybrid system? For consumers, who is more cost-effective?
Compared with household attributes, the two are not much different
Most users buy the 55KM endurance Qin PLUS DM-i may be used as a fuel car, and Geely Emgrand L Thor Hi · X's 100 km pure electric endurance is not as long as the 120 km version of the Qin PLUS DM-i, but it does not provide other options for the low endurance version, so in terms of choice diversity, Qin PLUS DM-i is slightly better.
Qin PLUS DM-i currently has two versions of 55k km and 120 km pure electric endurance, with a comprehensive endurance of 1180/1245 km and a feed fuel consumption of 3.8L/100km. Emgrand L Thor Hi · X has a maximum endurance of 1300 km and a feed fuel consumption of 3.8L/100 km when it is fully charged. From the perspective of book data, Emgrand L does not have obvious advantages, and the actual data will be verified after the new car is listed.
From the perspective of the positioning of the vehicle itself, both are models with strong household attributes, so practicality is the most concerned issue for consumers. For example, in terms of body size, the length, width and height of BYD QinPULS DM-i are: 4765mm/1837mm/1495mm, and the wheelbase is 2718mm. Emgrand L Thor Hi · X body size length, width and height: 4735mm/ 1815mm / 1478mm, wheelbase of 2700mm, in terms of size QinPULS DM-i will have an advantage.
Power comparison, Emgrand L Thor Hi · X is more powerful
Emgrand L Thor Hi · X is equipped with a 1.5TD+3DHT RCS Engine hybrid system, in which the 1.5TD turbocharged cylinder direct injection engine can output a maximum power of 133 kW, the peak torque is 290N·m, the official acceleration time of 100 km/h is 6.9s, and the transmission system adopts a 3-speed electric drive transmission (DHT Pro).
Qin PLUS DM-i is equipped with a hybrid system composed of a 1.5L naturally aspirated engine + EHS electromechanical coupling unit + blade battery, of which the maximum power of the 1.5L engine is 81KW and the maximum torque is 135N·m. In terms of endurance, it is divided into two versions, of which the maximum power of the motor of the 55km endurance model is 132kW, the peak torque is 316N·m, and the official acceleration time of the 100km-per-kilometer is 7.9s; the maximum power of the 120km endurance model motor is 145kW, the peak torque is 325N·m, and the official acceleration time of 100km-100 km is 7.3s.
The difference in power data between the two is not large, but in the case of power loss and high-speed driving, Emgrand L Thor Hi · The power advantages of the X's engine and the 3-speed transmission will be more obvious.
Hybrid technology comparison, different directions
IN BYD's hybrid system, the engine output shaft is not directly connected to the motor, but by a set of clutches responsible for coupling / decoupling, when the speed exceeds 60km / h, as the clutch is closed, the power output of the engine and the coaxial motor can be coupled with the motor on the other shaft / speed, thereby directly powering the wheel.
At low speeds, the engine will not intervene in the drive, and most of the working conditions are responsible for the motor, so the motor power is higher, and the pure electric driving is more dynamic.
Geely Raytheon hybrid is another design idea, not only the engine output shaft end of a set of clutches, the engine stop rotation does not affect the motor drive, to achieve machine electrolytic coupling; in addition, there are two sets of planetary gears between the dual motors in the coaxial layout, which can be coupled and power shunted.
Because of the three more physical gears, the engine can also intervene at low speeds; in addition, in pure electric mode, the motor can also be regulated through the planetary gear set, which can also amplify the torque and reduce the low-speed noise.
Put in two cars, Qin PLUS DM-i will ensure the power through the motor in pure electric driving or series mode; Emgrand L Thor Hi · X can have strong power in all working conditions.
summary:
In summary, Emgrand L Thor Hi · The difference between X and Qin PLUS DM-i is not large, Qin PLUS DM-i has more space and more choices; Emgrand L Thor Hi · X is a balanced development; as for the same hybrid system, Qin PLUS DM-i experiences pure electric driving better through a higher power motor, and Emgrand L Thor Hi · X maintains a balanced feature, but overall the dynamics are still better than qin PLUS DM-i; so consumers can choose as needed after determining their own needs.
