The rapid development of new energy vehicles is inseparable from the rapid advancement of new energy vehicle technology, especially plug-in hybrid models, which integrate fuel, plug-in, extended range, and pure electric functions. They are powerful and quiet. , intelligence and other aspects have also completely surpassed traditional fuel vehicles. In addition to being more fuel-efficient, there is no anxiety about battery life at all.
At present, almost every independent brand has its own plug-in hybrid technology. BYD has DM-i, Great Wall has Lemon hybrid, Geely has Thor hybrid, Chery has Kunpeng hybrid, and Trumpchi There are also Julang hybrids, which everyone is familiar with, but the protagonist today is not them, but the Dongfeng Mach electric hybrid PHREV which has accumulated a lot of experience.

Power system comparison
Dongfeng FengshenL7 uses the Dongfeng Mach electric hybrid PHREV system. This system uses the world's first power splitting + multi-speed series and parallel connection. The fusion configuration is the same as the latest BYD DM-i5.0 technical route. It can be purely electric, plug-in hybrid, and can extend the range. It is China's first hybrid SUV to break through 2000km and have ultra-long range. Dongfeng, an established car company, and BYD, a leading new energy car company, have successively launched power split + series-parallel hybrid solutions. It seems that this technical route will most likely become mainstream in the future. It is equipped with a 1.5T hybrid-specific engine. When paired with a motor, the comprehensive power is up to 265kW and the torque is up to 615N·m.

In contrast, the Galaxy L7 uses Geely's new generation Thor electric hybrid 8848 system. Among them, the maximum power of the 1.5T hybrid special engine is 120kW, the peak torque is 255N·m, and the engine thermal efficiency is 44.26%. Matched with the engine is a front-mounted permanent magnet synchronous motor with a power of 107kW and a torque of 338N·m. The entire hybrid system The comprehensive torque reaches 535N·m. The fuel consumption per 100 kilometers is only 5.23L; the CLTC comprehensive cruising range is 1370km.
（Geely GalaxyL7）
It is not difficult to see from the data comparison that Dongfeng Mach electric hybrid PHREV has obvious advantages over Geely Leishen electric hybrid in terms of power performance, engine thermal efficiency, fuel consumption performance and comprehensive cruising range, especially in terms of reduced fuel consumption. 1.43L/100km, achieving the best of both worlds in terms of power and fuel consumption.
Electric drive comparison
In terms of electric drive, Dongfeng Mach electric hybrid PHREV adopts the industry's first integrated hybrid electric drive, in which i-control intelligent electronic control has 26 types of electric drive scenarios are intelligently selected. The system can intelligently select pure electric, hybrid, and extended-range modes based on pre-judgment of the scene.
Simultaneous Mach electric hybrid PHREV integrates four-speed DHT series and parallel + power split model, integrating 1 There are three planetary rows, 3 pairs of fixed-axis gears and 2 sets of synchronizers. The structure is simpler and more reliable than similar models.

The Geely Thor electric hybrid uses a 3 variable frequency electric drive DHT Pro (the motor uses the P1+P2 solution). It has a total of 8 modes, namely pure electric mode, series mode, parallel mode, engine direct drive, full power driving, energy recovery, idle charging and reverse, namely "three gears in the entire range". The entire system has super 20 intelligent working modes.
（Geely GalaxyL7）
It is easy to see from the comparison that the 4 gear DHT electric drive used by Dongfeng Mach electric hybrid PHREV is compared with the Geely Thor electric hybrid< span>3gear DHT electric drive can better balance power and fuel consumption. Through the method of power splitting+ series-parallel fusion, it uses power splitting to ensure the smoothness of driving, and at the same time uses the 4 gear DHT to ensure high-speed driving. In terms of power and fuel consumption, the advantages and disadvantages of the two should be complemented to make it fast, economical and smooth, so that both power and fuel consumption can be better utilized.
