What are the pros and cons of manual and automatic transmissions in cars? Hurry, hurry! Please, 3Q

The manual transmission car has to change its own gears, the automatic car does not need to shift, only use the refueling brake, it is convenient to drive, the automatic transmission of the car is a little expensive to maintain, and the fuel consumption will be a little more than the hand transmission. Overall it's good. The manual transmission is more fun to drive, and women like the automatic transmission with more points.

1. The biggest difference between manual transmission and automatic transmission is that manual transmission needs to be matched with feet to shift gears, while automatic transmission does not need to step on the clutch at all; 2. Automatic transmission is divided into: ordinary automatic (gear) transmission, manual automatic transmission, and CVT continuously variable transmission; Recently, the DSG dual clutch has appeared.

The widespread use of manual and automatic transmissions proves their viability; At the same time, these two stalls have their own advantages and are suitable for different consumers; Manual transmission is more economical, affordable and fun to drive; The automatic transmission is easy to use and reduces the number of frequent gear changes (for example, hundreds of gears need to be changed hundreds of times during the 20-30km journey in Beijing); It is easy to follow the car and reduces the hidden danger of accidents; At the same time, with the progress of science and technology, the service life and quality of products continue to improve, the automatic transmission that has been used by high-end models has now begun to enter the ordinary model, presenting a new enjoyment, new way and convenient products in the public, which is also a manifestation of scientific and technological progress and social progress! Excluding factors such as driving technology and road congestion, fuel consumption is higher than that of manual transmission.

Advantages of manual transmission: high degree of freedom of gear control, good fuel economy. Disadvantages: long intermittent shifts, complicated operation, and the clutch pedal should be pressed with the left foot.

Advantages of automatic transmission: easy operation, no superfluous movements in the form process, complete rest of the left foot, short intervals between gear shifts. Disadvantages: Fuel economy is average, only gradual shift in gear order.

The most advanced is the semi-automatic transmission, which basically combines all of the above advantages.

Advantages of automatic transmission: trouble-free, eliminating the clutch pedal, no need to manually shift, only need to use the right foot, easy to operate, simple, and indeed very suitable for novices and female drivers.

Disadvantages: Fuel consumption, poor acceleration performance. It is easy to make mistakes and accidents.

Automatic transmissions are generally divided into: CVT, DSG, AMT and AT, and most of them are based on manual transmissions, with automatic shift control mechanisms. The difference between AT is relatively large, mainly including hydraulic torque converter, multi-plate wet clutch and planetary gear mechanism, which is more complex, large in volume and heavy in weight.

Advantages of manual transmission: fuel saving, good acceleration performance, displacement in the starting 500 meters of seckill, no problem at all. High engine speeds in low gears allow for high acceleration.

It can also do some special maneuvers, start with the tires, drift (the automatic does drift, the transmission breaks down quickly), leapfrog overshift, coast in neutral, and so on. It is not easy to have accidents with the wrong step.

Disadvantages: Complicated operation, requires the left foot to control the clutch pedal.

Manual transmission: the mechanism is simple, that is, the ordinary helical gear meshing, divided into 3 shafts or more than 3 shafts, the transmission is small in size (more than half of the volume of automatic transmission), light weight. There is no need for a torque converter, it is not easy to damage, and the simpler it is, the more reliable it is.

In front of the transmission is an ordinary dry clutch, and in front of the clutch is the flywheel at the output end of the crankshaft, which is very reliable and not easy to break.

This is the same as a camera, you say that it is better to have an automatic camera or a manual SLR. Of course, if you want to shoot well, you will choose a manual SLR camera. However, in reality, most people still buy automatic cameras. Why? The automatic camera is convenient and easy to master.

The same goes for automatic and manual transmissions.

If you want to experience the fun of driving, then of course it is good to have a manual transmission, how to balance the gear and speed, manual transmission, and give players more space to play with the car. At the same time, the manual transmission of skilled drivers is often better than the automatic transmission control because the speed and gear control are often better than the automatic transmission, so the manual transmission car is more fuel-efficient. At the same time, the car with manual transmission will be a little lighter than the car with automatic transmission, so the car with manual transmission is significantly more fuel-efficient than the car with automatic transmission.

However, this requires the driver to have skilled and reliable driving skills. Also, the manual transmission car will be much cheaper than the automatic transmission car, and it will be cheaper than the automatic transmission car in terms of maintenance and maintenance, which is also the advantage of the manual transmission car.

However, there are many people who are not so good at driving, or do not want to get tired while driving, so they choose automatic transmission.

Therefore, the choice of automatic transmission and manual transmission of the car varies from person to person and depends on the actual situation of the individual.

The automatic transmission is easy to operate and easy to master. Suitable for people who don't want to spend more time studying while driving.

The manual transmission is fuel-efficient, the car price is low, the maintenance cost is low, and you can enjoy the driving pleasure. However, the driving skills of the driver are relatively high.

Manual transmission, will not be eliminated. Because it has the advantage that automatic transmission cannot replace. The manual transmission can fully meet the driving pleasure, the manual transmission is cheap, the manual transmission structure is simple and easy to maintain, and the manual transmission is low and fuel-efficient.

If you want to experience the fun of driving, you can buy an automatic transmission, and if you want to drive an electric car for a manual transmission, it is too boring.

Automatic gear is only to give you forward gear, backward gear, uphill gear, parking gear, manual gear is parking without gear, forward according to the speed of their own choice of gear, backward a gear, another: manual gear will not be eliminated, automatic transmission personally feels only suitable for veterans or let rookies drive for a while.

Automatic car:

There is no need to step on the clutch in gear, so it is more convenient to drive when going up and down the slope and starting the park. The driving experience is superior.

Manual transmission of the car:

The starting speed is higher than that of the automatic transmission, and the operability is better than that of the automatic transmission after proficiency, and the fuel consumption is smaller than that of the automatic transmission.
