Which is better, manual transmission, automatic transmission or manual transmission?

The advantages and disadvantages of manual gearbox are as follows: (1) It can freely control the speed to start or accelerate or decelerate, which can maximize the performance of the engine; Simple and reliable structure, few problem models and wide range of applicable models;

Lubrication only depends on splashing to lubricate gears. The requirement for gearbox oil is very low, the cost of consumable parts is low, and the maintenance cost can be well controlled.

This is the main advantage of manual transmission. In the era when there was no dual-clutch gearbox, the shift efficiency of manual gear was extremely high, so many supercars would choose MT. However, with the normalization of traffic congestion and the technological progress of automatic gearbox, the shortcomings of manual gear gradually emerged:

Disadvantages: 1, the shift steps of hands and feet are complicated, and it is a little tired after long-term congestion-the reason for passenger cars to eliminate MT;

Disadvantage two, the reason why the shift efficiency is lower than millisecond gearbox performance cars such as double clutch and seamless shift eliminate MT;

Disadvantage 3: the energy-saving ability is worse. The transmission ratio width and gear number of manual gears are obviously smaller than those of automatic gears today. The MT gear of a passenger car is at most 6 gears, and the speed range responsible for each gear can only be pulled up at a high speed within a fixed transmission ratio. The automatic gear has developed to the entry-level same sixth gear, followed by the double clutch seventh gear, the at ~ 13 ninth gear, and the CVT continuously variable gearbox. With the upgrade of automatic gearbox technology, manual MT no longer has the advantage of fuel saving, which is also the reason why it will be completely eliminated in the later stage.

MT will eventually become history. At present, the proportion of manual transmission cars has been reversed, and the number of cars has fallen below 50%. Moreover, there are a large number of medium and large vans and vehicles that just need tools, such as miniature pickup trucks, which account for too little in passenger cars.

Automatic cars have become the first choice at this stage, with obvious advantages; In order to cater to this trend, major manufacturers also tend to position automatic cars in the middle and high end. Most of the manual shift MT cars are low-profile models that reduce the starting price, and the power is mainly low displacement or L power. Without sufficient power reserve, driving pleasure is impossible. This differentiated positioning also accelerated the disappearance of MT.

Therefore, except for tool-type vehicles that only reduce the cost of vehicles, as long as the budget allows, it is not necessary to consider MT for most family vehicles; For beginners, it is much safer to concentrate on observing the road conditions than to constantly struggle whether the automatic gearbox will stall. As for some cases of accidents caused by the automatic transmission not stalling, after all, they are very few. Fear of eating is not a commendatory term, we should first see the advantages and then the disadvantages, and comprehensively judge whether it is suitable for making a decision.
