As an important part of the automobile transmission system, the performance and reliability of the transmission have an important impact on the driving quality and safety of the vehicle, and the 8AT transmission and CVT transmission are two common transmission types, each with its own advantages and disadvantages. Who is better than the 8AT transmission or the CVT?Let's take Tucson L and CRV as examples to reveal the mystery!
The 8AT transmission refers to an automatic transmission with eight forward gears and one reverse gear, which has a higher transmission ratio range and better fuel economy, while providing better power delivery and acceleration performance.
5 years ago, the 8AT transmission left everyone with the impression that it was a high-tech and technology-intensive component, and few car companies could break it
In addition, the 8AT transmission also has better shifting smoothness and responsiveness, which can provide the driver with a better driving experience.
CVT transmission is a kind of continuously variable transmission, which changes the transmission ratio by continuously changing the width of the transmission belt, therefore, the transmission ratio range of CVT transmission is larger, which can better adapt to different driving conditions.
For CVT transmission, it is a fairly cheap transmission, because the transmission is easy to slip, durability and stability is not good, therefore, CVT is often used in combination with some small displacement engines, CVT transmission is often used in relatively low models.
Due to the changes in the cost of automobiles and the increasingly fierce competition in the automotive industry, 8AT transmissions are gradually low-end, and CVT transmissions are gradually high-end. There are two relatively best-selling models, the Tucson L and the CRV, which match 15T+8AT powertrain and 15T + CVT powertrain, for these two transmissions, what are the characteristics?
The Tucson L is a model equipped with an 8-speed automatic transmission. This transmission has a large range of transmission ratios, which can better adapt to different driving conditions, at high speed of 120km h, the engine speed of Tucson L is only a little more than 2000, under the matching of the transmission, Tucson L also has a more economical fuel consumption, according to the feedback of car friends, the fuel consumption of Tucson L is about 6 7L per 100 kilometers.
At the same time, the 8AT transmission has very good gear shifting smoothness, and the engine speed is relatively smooth, making the driving experience smoother, which further improves the driving quality of the vehicle.
Honda CRV is matched with Honda's self-developed CVT transmission, the structure of the transmission is steel belt type, compared with the 8AT transmission, its stability and durability are slightly insufficient, in addition, CVT in order to prevent its own steel belt slippage, in winter cold start, CVT transmission has cold start protection mode, the overall driving feeling is relatively sluggish.
However, the smoothness of the CVT transmission is better, in addition, because the oil pressure control of the CVT transmission is relatively agile, the CVT transmission has a very good response, and the transmission ratio of the transmission can be quickly reduced when the owner accelerates when he steps on the accelerator deeply, so as to quickly improve the acceleration of the vehicle.
As can be seen from the above analysis, 8AT transmission and CVT transmission have their own advantages and disadvantages, but as a family car, 8AT transmission has better durability and stability, and the fuel economy of 8AT transmission is also good, overall, 8AT transmission has a slight advantage.
