Which is more fuel efficient, automatic or manual? Why?

Whether it is fuel-efficient for automatic transmission cars or manual transmission vehicles depends on many factors, mainly: 1. The driver's driving skills; 2. Performance of automatic transmission.

From the perspective of the driver's driving technology, if the driver's oil separation is perfectly coordinated and the timing of the shift is very accurate, then the manual transmission car is slightly better than the automatic transmission in terms of fuel consumption. <>

From the perspective of the performance of the automatic transmission, the automatic transmission with excellent performance has a very good performance of the torque converter, this torque converter can amplify the output torque of the engine to about twice when the vehicle starts and accelerates (the ordinary friction clutch can only transmit torque 1:1), so in the process of starting and accelerating, the automatic transmission car has a strong advantage. A good automatic transmission, shift timing, shift speed are incomparable to the driver.

Therefore, from the above two points of analysis, the automatic transmission car should be fuel-efficient. <>

Some people say that manual cars are fuel-efficient, and this was true in the past, because automatic transmissions were not mature at that time. The power loss of manual transmission and automatic transmission is different, generally after the power is transmitted to the manual transmission, there will be about 5% power loss, and the remaining about 95% of the power is output from the manual transmission. The automatic transmission has a power loss of about 12%, leaving only 88% of the power output.

Manual transmission relies on gears to transfer energy, and the energy will be lost in the friction between the gears, so it consumes less. Automatic transmission relies on liquid to transfer energy, and liquid is used as a medium to transmit energy, so it consumes more. But now the automatic transmission manufacturers, have thought of this problem, so in order to solve this problem, the current automatic transmission is added to the lock-up clutch, when the two halves of the torque converter speed is similar, the lock-up clutch will connect them, so that there is no slippage between the automatic transmission, improve the transmission efficiency, so it is synchronized with the engine speed.

Basically, it can be compared to a manual one. <

Incidentally, due to the continuous maturity of the continuously variable transmission, it will be more widely used in vehicles, and when its technology is more mature, it will be more fuel-efficient than automatic transmissions.

You are still entangled in automatic and manual to this day, just take the city needs now, there is a mind is automatic transmission, can not say that it depends on what use, Wuling series is almost all manual transmission, because the use is different, just say to buy a better B-class joint venture series, there is also a manual transmission, almost all automatic, not to mention the high maintenance cost of breaking, people are almost not broken on the change of car, now the society is not like before, buy a bad Santana to open for more than ten years, now there is, in addition to pulling goods can be opened, so I said, you are fooling everyone, I don't think I know how to drive, right, you go and jump off the building.

A car with an automatic transmission is more fuel-efficient than a manual transmission? Used Cars Cars Car Knowledge.

The question of who is more fuel-efficient between manual transmission and automatic transmission seems to have been debated since the two systems were developed, and the general view was that in the case of the same brand, the same model, and the same configuration, the manual transmission car will be more fuel-efficient than the automatic transmission.

Modern people generally buy automatic transmission models when buying cars, and some cars that are used to manual transmission will laugh at automatic transmission models, thinking that this is a fool model, and step on the accelerator and go. It's the same as the popular "point-and-shoot" cameras of the past. Automatic transmission really makes driving a little easier.

But do you really drive an automatic transmission model? If you want to drive forward, hang D gear! Want to drive backwards, hang R gear, want to park, hang P gear?

Is it really that simple?

This is really a wrong concept, and it is a misunderstanding of many novice drivers!

First of all, don't open the D file to the end!

Moving forward is D gear, whether going up a hill or climbing a hill, many drivers will hang D gear. When you have a feeling of hanging D gear and climbing, the car will obviously become "meat", stop complaining that the car is not good to drive, saying that there is a problem with your driving habits!

If you change the climbing gear (marked "1", "2" or "L" on the base below the gear), the car will be lighter and more powerful on the slopes. This is to use the right gear, downshifting can also climb quickly, overtaking is trivial.

How to use the p, n, and r files?

P gear: Parking gear, used when parking.

N gear: short-term parking gear, used when temporarily parking on a flat road, such as waiting for a red light, you need to cooperate with the handbrake.

R gear: Reversing gear, used when reversing.

In China, most cities are congested with traffic, and when encountering frequent starts and stops, the technique of short parking comes into play.

How do I use the gears when I am parked and waiting?

Within 30 seconds: Use D gear with foot brake.

30 seconds to 1 minute: Use N gear with foot brake.

More than 1 minute: Use N gear with handbrake.

Long wait: Use the P gear with the handbrake.

Driving an automatic car, don't do these things.

1. Don't move the gear lever and dial it back and forth in D gear and other gears.

2. During driving, it is forbidden to dial the gear lever into N gear, and it is also forbidden to coast in N gear when going downhill.

Although many veteran drivers say that coasting in neutral is fuel-efficient, this does not apply to automatic transmission, because once dialed into N gear, the engine enters idle operation, and the fuel supply to the oil pump in the engine-driven transmission will be significantly reduced, which will lead to serious damage to the parts of the automatic transmission.

The car sales market is now divided into automatic transmission and manual transmission, many car owners are more hesitant when choosing a car, because they want to be more fuel-efficient in the process of driving, save their own expenses, in order to achieve such a purpose, should first understand the difference between automatic transmission and manual transmission, so as not to make a wrong decision. So which is more fuel-efficient, automatic or manual?

Many car owners will feel that from a theoretical point of view, the manual transmission can achieve a good fuel-saving effect, because the automatic transmission is more complicated in the installation process, so the fuel-saving effect will be worse, this idea is very reasonable, because the manual transmission in the process of driving, the gears are controlled by the owner himself, plus the manual gear clutch, the transmission efficiency is high, and the effect of fuel saving can be seen naturally.

For some old drivers who often drive, the manual transmission operation is very flexible, but it seems that the automatic gear can not achieve such an effect, although many data providers hope to be able to make up for the shortcomings of the automatic transmission in this regard, but it seems that the effect is not obvious, fuel consumption is still very strong, not only that, the automatic transmission also has no way to manually direct fuel, which is also a place that needs to be improved.

Many car owners with automatic gears know that it is very convenient in the process of driving, and the main reason is that its structure is very complex, there are many small parts, of course, the weight will increase, and it will be more expensive than the manual gear car model when it is sold.

It can be seen from the gap between the two gears of the automatic transmission and the manual transmission, the automatic transmission is still relatively backward, the manual transmission has a lot of simple and direct structures in the production process, so that the number of these two models in the gear is the same, but in comparison, the structure of the manual transmission is not so complex, and the technical requirements are not so high, so the cost is lower, the price is lower when selling, the cost performance is higher, and it is more in line with the consumer needs of the public, and it is generally about 10,000 yuan less than the automatic transmission in the market.

Of course, the transmission technology of the automatic gear is still very mature and can be loved by many consumers, but it is relatively expensive to maintain in the process of production, which is why many old drivers prefer automatic transmission.

In life, no matter what gear you choose, the model has its own advantages and disadvantages, because no matter what it is impossible to do, there are no disadvantages, or you should choose according to your own economic situation, so that you can make yourself more comfortable in the process of driving.

First, look at their transmission efficiency.

Most of the manual transmission cars use gearbox transmission, which has high mechanical transmission efficiency and low delay, so the output efficiency is also very high. The transmission of automatic transmission vehicles is realized by transmission oil and torque converter, which causes a relatively large transmission loss. Therefore, in terms of transmission efficiency, manual transmission cars are better, and the relative fuel consumption is lower than that of automatic transmission cars.

Reflected in fuel consumption, it is more fuel-efficient to manual transmission.

Second, the transmission structure.

The internal structure of the automatic transmission is much more complex than that of the manual transmission due to the automatic shift of the transmission to achieve automatic shifting, so there are many internal parts, and the weight must be heavy. The internal structure of the manual transmission is relatively simple, so it is much lighter than the automatic transmission in terms of weight. Of course, the heavier the baggage, the higher the fuel consumption.

Third, driving habits.

In fact, whether the automatic transmission car is fuel-efficient or manual is fuel-efficient, a large part of it depends on the driving habits of the owner. Many car owners have bad driving habits, so no matter what kind of car they drive, it will be very fuel-guzzling. There is also a novice driving, if a novice drives a manual transmission car, it must be much higher than the fuel consumption of the automatic transmission car, and the manual transmission car must have a certain run-in period.

So in the end, what kind of car is fuel-efficient, the driver's driving habits may be very important, and developing a good driving habit is the most important.

A car with an automatic transmission is more fuel-efficient than a manual transmission? Used Cars Cars Car Knowledge.

Relatively manual is better, but there is also a relationship between individual operation and use.

The fuel consumption of automatic transmission is higher than that of manual transmission under the same conditions because there is a fluid coupling in the transmission of automatic transmission car, which will lose part of its energy during operation, which is the main reason for the higher fuel consumption of automatic transmission car than manual transmission car. But it should also be related to everyone's driving habits, such as sharp acceleration, sudden braking, low-speed high-end, high-speed low-gear and other bad habits.

The automatic transmission is fuel-efficient, and the manual transmission is fuel-efficient.

At a time when oil prices continue to rise, fuel conservation has become a daily operation for many drivers. Because the proportion of charges in car consumption is the largest, many people consider fuel consumption before buying a car, and many old drivers are exposed to it, and they hear rumors that manual gears automatically save fuel than others, and start manual gears. So is a manual transmission really more fuel-efficient than an automatic transmission?

In fact, manual transmissions are mostly more fuel-efficient than automatic transmissions.

Because, under the premise that the driver is proficient, the old driver can master the time to change gears, so he can choose the most economical engine speed, so that the gear can adapt to the speed and driving needs to meet the driving needs. However, if the driver of the manual gear is a novice, it will cost more fuel than the automatic gear due to the unskilled operation. Therefore, whether or not to save manual fuel depends on the driver's driving experience.

Manual stop, automatic stop fuel-saving comparison, who is the real king of fuel economy. In the same way, old drivers try not to step on the accelerator and brake sharply, reduce idle time, etc., and develop fuel-efficient driving habits, and know how to reduce fuel consumption unconsciously. Beginners are still adding new cars in the process of exploration, and it is normal for the initial fuel consumption to be high.

Among them, the fuel non-technical "advanced low speed" in the mouth of old drivers continues to spread widely. When driving a manual transmission, you can reduce fuel consumption by relying on the engine to slowly increase the speed without dropping the gears. The old drivers have manual transmissions in their mouths, but in fact it is very complicated to achieve the purpose of manual transmission, other drivers, other models.

So, if you're a new driver, you can opt for an automatic car that's easier to drive. In the face of technological innovation in various fields, many automata technologies are constantly being upgraded. New materials and technologies reduce electric losses, and shifting is rationalized.

There are many automatic transmissions at high speeds, so the automatic transmissions are shifted on the computer, and the close-to-support ratio changes frequently.

Of course, it is not contradictory that car owners who like automatic transmissions can choose cars with built-in CVT when buying a car, and veteran drivers who are familiar with manual transmissions can also choose their favorite manual transmission. Most people need to consume a lot of fuel if they want to get power, and if they want to save fuel, it is not a problem to get rid of power, but in today's continuous development of technology, saving energy and money is already out of reach.

Cars with automatic transmissions are more fuel-efficient, because such cars are very advanced and have a particularly high utilization rate of gasoline.

Hello, I am inquiring about the relevant information for you and will reply to you immediately.

Dear, hello, many people with experience in driving know that manual transmission cars are more fuel-efficient, because they drive manual transmission cars are sometimes lower than the official fuel consumption, so it must be more fuel-efficient, on the other hand, the manual transmission car strain speed is still stronger than that of automatic transmission, which is also another advantage of manual transmission, just like many times the car will use manual transmission, manual operation shifting, should be changed in time. The automatic transmission car is relatively stable, but the automatic transmission is more complex than the manual transmission of the car, and there are many more parts, so it is more fuel-efficient, and it is difficult for the automatic transmission to have an advantage in fuel consumption, but the automatic transmission car is indeed better than the manual transmission car, especially for girls and novices, the automatic transmission does not need to start frequently, clutch, very convenient, and can release the left foot, much more convenient than the manual transmission, and it will not be very tiring to drive in a short time. Isn't it often said that?

Automatic is that"Fool car", sit on it and you'll be on the road. This is not entirely true, but the automatic transmission is indeed much friendlier than the manual transmission. However, what scares me most about automatic transmission models is its safety, and I believe you have seen a lot of accidents caused by the wrong accelerator and brake pedal.

In short, if you want to choose a more fuel-efficient car, it is recommended to choose a manual transmission, and the old drivers can also choose a manual transmission, because for you the manual transmission has been as easy as the automatic transmission, if you are a woman and a novice, it is still recommended that you choose the automatic transmission, after all, the automatic transmission is indeed better than the manual transmission, on the other hand, it is more stable.
