On January 7, Chery's Xingtu Automobile released the "Star Core Power ET-i Full Engine Super Hybrid" technology, which is the fifth independent brand with super hybrid technology after BYD DM-i, Great Wall Lemon Hybrid DHT, Geely Leishen Power and Changan iDD. The content of the technical conference is quite hardcore, do you understand? It doesn't matter if you don't understand, the corner master of this article will interpret it for everyone.
The core of Xingtu Automobile's "Star Core Power ET-i Full Engine Super Hybrid" technology can be covered by "3 Engine 3 Gear 9 Mode 11 Speed", and to expand, the 3 Engine contains a gasoline engine and two drive motors. Among them, the gasoline engine covers 1.5T four-cylinder engine and 2.0T four-cylinder engine, the maximum power of the 1.5T engine is 115 kilowatts, and the peak torque is 230 Nm. The other two motors are connected to the dual clutch transmission, one of which is located in the P2 structure and the other in the P2.5 structure, which have a power of 55 kW/160 Nm and 70 kW/155 Nm, respectively.
We see through a simple structural diagram that the P2 motor is located behind the C0 clutch, which is arranged on an output shaft with the 2 gear ratio, while the P2.5 motor is mainly responsible for the 1st gear and 3rd gear gear ratio, which forms a 3-speed DHT transmission with more prominent economy and smooth driving quality, which is fundamentally different from the traditional double clutch.
So speaking of this, there may be students who have seen the difference between it and the DHT Pro transmission in Geely Thor Power. Geely said that its DHT Pro transmission also has 3 gears when releasing Thor Power, and compared with The Starway, Geely Thor Power DHT Pro has a P1 and P2 structure. Analyzing at the technical difficulty level, it is clear that Xingtu engineers will have to face more problems to overcome.
In terms of drive structure, star core power ET-i contains two-wheel drive and four-wheel drive, the two-wheel drive version of the comprehensive output power of up to 240 kilowatts, and the four-wheel drive version of the official data is more eye-catching, the comprehensive power can reach 338 kilowatts, and the 100 km acceleration can enter the 4-second club. It is mentioned here that Geely Automobile introduced the concept of "torque output on the wheel" when releasing Thor Power. At the star core power ET-i conference, Xingtu also introduced the wheel torque output of this system, of which the two-wheel drive version has more than 4000 Nm of torque on the wheel, and the four-wheel drive version is more than 6300 Nm.
Then there is the "9 mode", as the name suggests, there are 9 working modes, including single motor pure electric, dual motor pure electric, engine direct drive, parallel drive, parking charging, driving charging and so on. And Geely Thor Power can only provide simple 4 working modes. The advantage of multi-mode is the flexible application in life scenarios, while making the fuel economy of the vehicle more prominent.
Finally, there is the "11-speed". According to The Xingtu engineers, they can theoretically achieve 29 speeds, that is, 29 gears, when developing this system, but the actual scene application does not need so much, and finally reduced to 11 gears. The 11-speed can cover the gear combination of all car scenes, including urban commuting, long-distance travel and extreme road conditions. The fuel saving rate of low power mode > 50%, the fuel saving rate of urban working conditions >55%, and the fuel saving rate of high-speed working conditions > 35%.
The first mass production car equipped with Star Core Power ET-i has been released, which is the StarWay Wind Chasing ET-i, which is a two-wheel drive version, 1.5T four-cylinder power maximum power of 240 kilowatts, comprehensive torque of up to 510 Nm, 100 km acceleration of 6.8 seconds, more importantly, the car is plug-in hybrid, can be on the green card, pure electric endurance of 105 km, comprehensive endurance can exceed 1000 km, under the condition of power shortage of 100 km fuel consumption of 4.8L.
Master Horn wants to say:
Finally waited for Chery's own super hybrid system, did not disappoint the waiting fans, this system is very advanced in technology, in the current market super hybrid system has its own unique characteristics. Compared with BYD DM-i, Great Wall Lemon Hybrid DHT, Geely Raytheon Power, Changan iDD system, which one are you more optimistic about? Feel free to leave a message in the comments section.
