In the past few years, the trend of pure electric vehicles has risen, many car companies have been involved in this field, in recent times, hybrid technology has become an outlet, and some independent brands have devoted themselves to it. There are two main reasons behind it, first, although pure electric vehicles are the most popular new energy vehicles, mileage anxiety is inevitable, long-distance driving is not comfortable enough, so consumers have a higher degree of acceptance of hybrid models; second, after years of technology research and development and precipitation, independent brands have begun to enter the harvest period, and can realize the wrist of the platform level and the joint venture brand. On January 7, Xingtu released the star core power ET-i full engine supermix technology, which officially claimed to have the advantages of "3 engines, 3 gears, 9 modes and 11 speeds", what are the highlights of this set of power? This article analyzes this.
What does "3 Engine 3 Gear 9 Mode 11 Speed" mean?
"3 engine", this is easier to understand, popular point is to have three sources of power output, the first of which is the traditional internal combustion engine, Xingtu for this hybrid system specially created a 1.5T turbo engine, the maximum power of 115 kilowatts, the maximum torque of 230 Nm, in addition to this head, this hybrid system of the special engine also includes 1.5TGDI and 2.0TGDI two, better parameters, suitable for models with higher demand for power. The other two "engines" are two motors integrated in the enclosure with a maximum power of 55 kW and 70 kW and a maximum torque of 160 Nm and 155 Nm, respectively. Built-in two motors, which are relatively rare in the industry, can not only bring stronger power output, but also meet more working conditions, so that the driving state of the vehicle is more in line with the current environment.
"3 gears" means that this power combination has three gears, what is this concept? At present, the domestic mass production of similar hybrid models, generally only have one or two gears, Xingtu's hybrid system has three physical gears, the benefits are obvious, especially in the high-speed driving section, higher gears can effectively reduce the speed, improve energy consumption performance.
"9 modes" refers to the fact that this power combination has nine working 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. In addition, these working modes can be automatically switched according to different driving scenarios, for some novice users, do not have to worry about which mode to choose at the moment, the system will automatically help you make a choice.
"11 speed" refers to the 11-gear combination, which is the 11 gear combinations selected by the engineers after actual measurement and analysis that can cover all car scenes. To give a few examples you can understand, for example, when you just started, it is the stage of the lowest efficiency of the internal combustion engine and a large load, then set the dual motor mode, the internal combustion engine is in a dormant state, the energy consumption is reduced, and you can also feel the strong starting torque brought by the dual motor; for example, at low and medium speed, this time does not need too much power output, then switch to a single motor mode, the energy consumption is further reduced; for example, when overtaking, you need to output a strong power in a short period of time to ensure that the entire overtaking process is safe and fast. At this time, the total power of the three engines, the torque output of 510 Nm is comparable to that of a six-cylinder gasoline engine; for example, in the stage of high-speed cruising, this is the best working condition of the internal combustion engine, you can turn off the motor, so that the internal combustion engine is directly driven.
Having said all that, what is the use of this system?
After understanding the details of "3 Engine 3 Gear 9 Mode 11 Speed", let's talk about what kind of benefits star core power ET-i full engine supermix technology brings to users.
First of all, high performance, it is not difficult to imagine, an internal combustion engine and two motors will bring a kind of parameter performance, the total power of the four-wheel drive version reaches 338 kilowatts, zero hundred acceleration only takes more than 4 seconds, comparable to a million-level sports car, and the entire gear shift process has no power interruption, and the driving process is close to pure electric vehicles.
The second is low energy consumption, on the basis of 1.5T engine, intelligent dual motor torque distribution, etc., the transmission efficiency of "Star Core Power ET-i Full Engine Supermix" reaches 97.6%, even in the state of power loss, the fuel consumption is only 4.8L/100km.
What was the first model to be equipped with this system?
The answer is Star Trail ET-i. In terms of appearance, this car is not much different from the ordinary version of the car, the front face is still the iconic family design of Xingtu, the through-type taillights at the rear of the car have also been retained, and there is a PHEV logo in the lower left to highlight its special identity.
In addition to the appearance, we are most concerned about its performance indicators, the new car is equipped with a plug-in hybrid system composed of a 1.5T engine and an electric motor, and the transmission part is a hybrid gearbox. Its standard version of the pure electric endurance can reach 105 kilometers, compared with the current common 60 or 70 kilometers of pure electric endurance, the advantages are still quite obvious, and its comprehensive cruising range of more than 1000 kilometers.
Summary of the full text
It is foreseeable that before the major breakthrough in battery technology, hybrid system models have a relatively broad market prospect. Star core power ET-i full engine supermix technology launched by Xingtu, in my opinion, there are two biggest highlights, one is the integration of dual motors, one is to have three physical gears, which is rare in the current industry, is the existence of technical barriers, I believe that after the listing of many models equipped with this set of power in the later period, it will cause pressure on opponents such as BYD and the Great Wall.
