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

实际上，档位越多并不意味着车就越好，不过意味着更贵，所谓的档位多就好的说法更多的是来自于厂商宣传。那么档位少就真的是落后该淘汰了吗？

In fact, more gears do not mean that the car is better, but it means more expensive. The so-called saying that more gears are better comes from the manufacturer's publicity. So is it really backward to be eliminated if there are few gears?

事实：如今汽车变速箱的档位越来越多，实际上各大车厂为了提高变速箱传动效率、减少碳排放做出的技术处理和升级改造。

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

因此，这并不意味着4速变速箱就比6速、7速变速箱的技术落后，因为20年前的速换挡逻辑，和20年后的换挡逻辑，原理是一样的，而不一样的则是多档位变速箱多了几个齿轮一样，无非是加工精度等要求更高了，成本更高了，这就好像自行车，你不能说27速的自行车，要比18速的自行车更高 级。

Therefore, this does not mean that the technology of 4-speed gearbox is behind that of 6-speed and 7-speed gearbox, because the principle of speed shift logic 20 years ago is the same as that of 20 years later, but the difference is that multiple gears are added to the multi gear gearbox, which requires higher machining accuracy 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.

再说说档位的事儿，很多人都说档位越多动力传递越平顺，事实上是档位越多，变速齿轮也就越多，档位切换相对就越频繁，顿挫感就越小，变速箱传动也就越平顺。逻辑没有错，但问题是换挡跟档位多少没什么太大干系，与车辆出厂前的调校和电脑的处理有关。

As for gears, many people say that the more gears there are, the smoother the power transmission is. In fact, the more gears there are, the more gears there are, the more frequent the gear switching is, the less the frustration is, and the smoother the transmission of the gearbox is. The logic is correct, but the problem is that the shift has nothing 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.
