When people buy a car, they first focus on whether the quality of the car's "three major parts" (engine, gearbox and chassis) is reliable. As long as the "three major parts" are of good quality, they will consider the car to be a good car. . Although this view is rather one-sided. After all, a car is composed of tens of thousands of parts, and the "three big parts" are only part of it, but I have to say that the "three big parts" are indeed a very important part of the car. Affects the user's use of the vehicle.
In the early days of my country's automobile development, our "three major" technologies have always lagged behind those of foreign countries. This is also the problem that domestic independent automobile brands have complained about to consumers the most for a long time. However, with the vigorous development of my country's automobile industry, independent brands have continued to increase their investment in research and development of the "three major parts", and have made many breakthroughs in automobile core technologies and parts manufacturing processes. Some technologies have not had much difference with joint venture brands. difference. Take Chongqing Qingshan Industrial Co., Ltd., a well-known domestic gearbox manufacturer, as an example. It has become a gearbox supplier for most domestic independent brand car companies, and has been recognized by consumers in terms of quality and technology.
Chongqing Qingshan Industrial Co., Ltd. belongs to China Ordnance Equipment Group Co., Ltd. It has embarked on the road of integrating military and civilians since 1984. In 2009, it independently developed the first domestic AMT automatic transmission and realized industrialization. In 2011, it became the first domestic gearbox company with production and sales exceeding 10 million units. In 2020, the production and sales of DCT gearboxes exceeded 400,000 units. It has a nationally recognized enterprise technology center and a national test center certified by CNAS, forming a global layout of "seven centers in two countries, three places", and the company has 215 valid patents, including 80 invention patents. It can be seen that Tsingshan Industrial has become my country's star gearbox enterprise, attracting most of the domestic independent automobile brands to cooperate with it.
As a pioneer of domestic independent brands, Chery Automobile has long been in in-depth cooperation with Tsingshan Industrial. Its recently launched new model Jietu X70? Plus and the new generation Jietu DF727C series 7DCT wet dual clutch transmission. The transmission has the advantages of smooth power output and low fuel consumption, bringing users a comfortable driving experience.
I happened to participate in the test drive of the new generation Jietu X90 (hereinafter referred to as the new Jietu X90) in Chongqing, and I happened to experience the performance of the 7DCT wet dual-clutch gearbox independently developed by Tsingshan. Chongqing is known as the "8D Magic City". It got its name because the city is full of uphill and downhill mountain roads and is full of intricate overpasses. It is precisely because the road conditions in Chongqing are very complicated that the test drive of the new Jietu X90 here is also more challenging.
The new Jietu X90 is equipped with Chery’s third-generation ACTECO1.6TGDI engine, with a maximum power of 145kW and a maximum torque of 290N·m. It is matched with a 7DCT wet dual-clutch gearbox. Although the data performance of this power system is not very fast, it is sufficient for daily use. After all, the Jietu X90 is positioned as a comfortable and luxurious mid-size SUV.
In my actual driving experience, the power output of the new Jietu X90 is indeed very smooth, and the throttle control is easy for people to get started. Just tap the accelerator to drive the vehicle, and the power output is very soft. This setting feels quite comfortable when walking on the mountain roads in Chongqing. Because on the roads in Chongqing, we often need to start on a half-slope, but with the automatic parking and hill assist system, the driver will be very calm even when facing a half-slope start, and will not worry about the car slipping away just because of the half-slope start. Press the accelerator a little and the vehicle will jump out. As long as the driver slowly and deeply steps on the accelerator, the vehicle can start on a half-hill slope gracefully and powerfully, and it can also protect the gearbox to a certain extent.
In terms of the shifting feeling of the new Jietu X90 when driving at high speed, whether it is upshifting or downshifting, it is very crisp and clear. Its shifting feeling is the change in acceleration, which can give the driver a great engine noise response.
During large-throttle downshifts, the 7-speed DCT gearbox sometimes briefly stops in the middle gear to respond to the driver in time, and then prepares to downshift to the target gear. This response brings a pleasant driving experience to the driver.
The new Jietu X90 is equipped with 7 11 active safety technologies in terms of assisted driving, and has L2 automatic assisted driving. The specific configuration includes: adaptive cruise system, automatic emergency braking system, lane keeping assist system, lane departure warning system, traffic jam assist system, traffic speed limit sign recognition system, intelligent high beam assist system, electronic stability control system, hill assist, forward collision warning, rollover prevention system, etc., to provide drivers with It provides more safety protection and makes driving more relaxed and comfortable.
In addition to bringing users a smooth and comfortable driving experience, the new Jietu X90 also brings users a comfortable driving experience in terms of interior design. It is equipped with a dual 12.3-inch large horizontal screen design used in a luxury brand car, bringing you an experience like a mobile theater. The car-machine system equipped with this screen supports 4G car networking, mobile phone remote control, full-time voice control, etc., showing a sense of technology and bringing a good human-computer interaction experience. It also has Adient light luxury fine leather luxury seats, which are ergonomically designed and have heating and ventilation functions. The riding comfort and wrapping are very good.
Items After this test drive experience of the new Jietu X90, I felt a lot of emotions. I used to think that independent brands are not as good as joint venture brands in many aspects, but after experiencing the new Jietu X90 this time, I found that our independent brands have made more progress than just a little bit. Judging from the new Jietu X90 I test-drove, it is no exaggeration to say that the "three major components" it carries are not inferior to the joint venture brands in terms of experience. However, the price of the new Jietu X90 is only more than 70,000 yuan. The starting price is just over 140,000 yuan for the top model, which is really good in terms of cost performance.
