Of course, in real life, many friends are asking, the more stalls a car has, the better it is? Is it not worth buying a car with few gears? A lot of people will think that the better the gear, the better it is. Is that really the case? Let's analyze it.

實際上，檔位越多并不意味著車就越好，不過意味著更貴，所謂的檔位多就好的說法更多的是來自于廠商宣傳。那么檔位少就真的是落后該淘汰了嗎？

In fact, more gears does not mean the car is better, but it means more expensive. The so-called saying that more gears is better comes from the manufacturer's propaganda. So less gear is really behind the elimination of it?

事實：如今汽車變速箱的檔位越來越多，實際上各大車廠為了提高變速箱傳動效率、減少碳排放做出的技術處理和升級改造。

Fact: Nowadays, there are more and more gears in automobile gearboxes. In fact, in order to improve transmission efficiency and reduce carbon emissions, major automobile manufacturers have made technological treatment and upgrading.

因此，這并不意味著4速變速箱就比6速、7速變速箱的技術落后，因為20年前的速換擋邏輯，和20年后的換擋邏輯，原理是一樣的，而不一樣的則是多檔位變速箱多了幾個齒輪一樣，無非是加工精度等要求更高了，成本更高了，這就好像自行車，你不能說27速的自行車，要比18速的自行車更高 級。

Therefore, this does not mean that the 4-speed gearbox is behind the 6-speed and 7-speed gearbox in technology, because the principle of the speed shift logic 20 years ago is the same as that 20 years later, but the difference is that the multi gear gearbox has several more gears, which only requires higher machining precision and higher cost. This is like a bicycle, you can't say a 27 speed bicycle, It's more advanced than an 18 speed bike.

再說說檔位的事兒，很多人都說檔位越多動力傳遞越平順，事實上是檔位越多，變速齒輪也就越多，檔位切換相對就越頻繁，頓挫感就越小，變速箱傳動也就越平順。邏輯沒有錯，但問題是換擋跟檔位多少沒什么太大干系，與車輛出廠前的調校和電腦的處理有關。

When it comes to gears, many people say that the more gears there are, the smoother the power transmission will be. In fact, the more gears there are, the more frequently the gears are switched, the less frustration there will be, and the smoother the transmission will be. The logic is correct, but the problem is that shifting has little to do with the number of gears, which is related to the adjustment of the vehicle before leaving the factory and the processing of the computer.
