On January 7, Xingtu Automobile's "Star Core Power ET-i Full Engine Super Hybrid" technology was officially released. At present, domestic hybrid technology can be said to be a hundred flowers blooming, and major car companies have their own unique technologies, but only star core power ET-i full-engine supermix technology has been listed as a key special project of "new energy vehicles" in the "Thirteenth Five-Year Plan" national key research and development plan, which can be called national "black technology".
Then you netizens may have to wonder, star core power ET-i full engine supermix is stronger than other hybrid technology in the end? After the detailed interpretation of the press conference, the unique features of the Star Core Power ET-i Full Engine Supermix are actually hidden in the "33911" set of numbers.
The first "3" represents 3 engines. The driving force of common hybrid models on the market is roughly divided into two kinds, one is a single motor drive, the engine is only used to generate electricity, and the other is mainly driven by a single motor, and the engine can give a certain boost at the right time, and can only reach 2 engines at most.
The "1 engine" of the Star Core Power ET-i full engine super hybrid is a 1.5T hybrid special engine with a maximum power of 115kW and a maximum torque of 230N.m. In addition, the "2 engines" are two motors integrated in the DHT transmission with power and torque of 55 kW / 160 N.m and 70 kW / 155 N .m respectively. Compared with the existing hybrid technology, all 3 engines can participate in the drive, which lays the performance advantage of the Star Core Power ET-i Full Engine Supermix.
The second "3" represents 3 gears. The Star Core Power ET-i Full Engine Super Hybrid Architecture has 3 physical gears, which can better balance power and fuel consumption at low, medium and high speeds, so that the engine and motor are kept in the efficient operation range.
The number 9 represents "9 modes", which means that vehicles equipped with star core power ET-i full-engine super-hybrid technology have 9 operating modes, including 9 driving modes such as single motor pure electric, dual motor pure electric, engine direct drive, parallel drive, parking charging, and driving charging.
The 11 represents "11 speed", through different road conditions to match different driving mode of work, Xingtu engineers calibrated 11 gear combinations that can cover all car scenes. For example, the use of dual-motor pure electric drive at the beginning not only avoids the low efficiency of the engine at the beginning, but also makes the start fast and powerful; When driving at low and medium speeds, there is no need for large torque, and at this time it will switch to single motor drive to get lower energy consumption; In the middle and high-speed range, the use of engine direct drive has become a more energy-efficient option, and when the power is needed to accelerate and overtake, the 3 engines will be in unison, outputting up to 510N.m of amazing torque.
Of course, all switching does not require user intervention, and it is even difficult to be detected under the control of the intelligent system, which ensures the smoothness of the power switching.
In the past, the power and energy consumption of cars often could not be combined. The star core power ET-i full-engine supermix technology breaks this law. In the future, the total power of four-wheel drive models equipped with this system can reach 338kW, the maximum wheel torque exceeds 6300N.m, and the acceleration of 100 kilometers can easily enter the 4s class, and the performance is comparable to that of the million-level supercar.
Thanks to the seamless cooperation of the 3 engines, the transmission efficiency of the Star Core Power ET-i full-engine supermix system has reached 97.6%, the comprehensive fuel consumption can be as low as 1L/100km, and the feed fuel consumption is only 4.8L/100km.
See here may have been a lot of netizens have been planted, it is understood that the star core power ET-i full engine super hybrid is about to be installed on the upcoming star chase ET-i, the standard version of this car can reach pure electric mileage of 105km, comprehensive driving range can exceed 1000km.
Red dot observation:
Just a year ago, plug-in hybrid technology was not optimistic, but with the hot sales of BYD DM-i models, plug-in hybrid has also received more and more attention from car companies.
Through a large number of investment in research and development, today's plug-in hybrid models can not only be exempted from purchase tax on the green card, but also have a qualitative improvement in energy consumption and performance.
In particular, the emergence of star core power ET-i full-engine supermix technology can be said to have pushed the hybrid technology from the 1.0 stage to the higher stage 2.0 stage, which also makes people more full of expectations for the Starway ET-i model. It is believed that in 2022, Xingtu Automobile's "Star Core PowerED ET-i Full Engine Super Hybrid" technology will become the biggest competitor of BYD DM-i!
