Do you use S or D gear to run at high speeds?

In order to figure out what gear to use when running at high speed, the first thing we need to do is to figure out what these gears do and how they work. The "S" gear on the car can also be called a sports gear, which is used to delay the engine upshift, so that the vehicle revs higher, so as to stimulate more power; The "D" gear is the forward gear of the automatic transmission car, and when it is hung in the D gear, the car will actively upshift, so that the speed is kept at a relatively low level, so as to reduce fuel consumption and improve fuel efficiency, so when you usually run at high speed, choose the "D" gear is OK.

The S gear is a great way to experience the driving pleasure of the car, but at the same time the fuel consumption increases. When running at high speeds, we usually use D gear to do the trick. If you're trying to complete a quick overtake, or if you're racing a car, you can use S gear.

I usually choose D gear, because the consequences of driving in S gear for a long time are obvious, that is, fuel consumption will be on the high side, which is easy to understand, high power for better acceleration response, of course, need higher fuel consumption support. At the same time, noise may increase due to the higher engine speeds.

Is the car in S or D gear when running at high speeds? We know that when running at high speed, the vehicle will always maintain a relatively fast speed cruise, except when overtaking or when there is a change in traffic jam, the speed will be relatively constant at other times, in such a working condition, the engine does not need to have much power to deal with rapid acceleration, only need to have the power to overcome air resistance to maintain speed, so there is no need to hang to the S gear to let the engine rev high, which will be a waste of fuel.

S gear can also be used when running at high speed, that is, when overtaking, sometimes D gear step on the accelerator and downshift is not positive enough, the power is not out, at this time directly pull the gear to S gear, it will immediately downshift and speed up, it is more applicable on the national highway, because the lanes on the national highway are mixed, and the overtaking with greater power will be faster and safer.

Under normal circumstances, high-speed constant speed, the engine does not need to work at a very high number of revolutions, generally speaking, when the car is driving at a speed of 120km per hour, the speed of the engine does not exceed 3000 rpm, at this time, if the S gear is used, the speed of the engine will be increased some, in order to maintain speed, the gearbox may be lowered by a gear, the shift logic is biased towards performance, downshift in advance and delay upshifting, using the low gear of the gearbox, so that the speed of the engine increases, and the speed of the engine increases, The output power will increase. As a result, the car achieves better acceleration responsiveness.

High-speed cruise, when you don't need to accelerate with great power, you can choose to use D gear to open normally, if you want to accelerate sharply, when overtaking, you can directly pull to the S gear, and then hang back to the D gear after overtaking.

Generally use D gear at high speed, and use S gear when overtaking, so that fuel consumption is lower.

When driving Magotan to run at high speed, I tried to run 110km h when hanging in S gear, the gear is still in 6th gear, not rising to 7th gear, the speed is also more than 2,000 rpm, a little step on the accelerator will rise to nearly 4000 rpm, in exchange for the ability to accelerate quickly react, but it will consume more fuel. But the D gear will save a lot of fuel.

Running at high speed must use ddang, otherwise how can you run out.

Use D gear for high speed, because D gear is like a long-distance runner who is good at thinking. It will optimize the transmission based on the vehicle's driving situation and theoretical strategy. There is no doubt that D gear is suitable for driving on the highway.

If you choose S gear, this may increase your fuel consumption, because on the highway, the car will basically maintain a steady speed and will not need to accelerate for long periods of time. The speed of the car in S gear will be faster, and the fuel consumption will also be higher.

The gear is the forward gear, also called the active gear. Generally, the use of D-gear in the city is not a big problem. When using D, the transmission automatically shifts and upshifts or downshifts based on everyone's real-time speed.

The S gear is a sport gear. When using the S gear, you can switch gears freely, but the timing of the gear shift is delayed, and the engine keeps running at high speeds, which in turn increases the car's power. Therefore, it is generally possible to overtake or climb a hill with S gear, which can provide a lot of power and allow the car to complete the action quickly.

But when you step on the throttle, the D gear reacts a little slower than the S gear.

2.Many friends are accustomed to stepping on the brakes and then shifting gears, and think of automatic brakes as a clutch for manual transmission. Although this is a good habit, we don't need to apply the brakes when switching between S and D, and how to shift gears is also covered in our car manual.

When cruising at high speeds, you can choose to use D gear to open normally. If you want to accelerate quickly, you can pull directly into S gear when overtaking, and then go back to D gear after overtaking.

3.The traffic police popularized the number of people who used various gears, and most of them used D gears. The D gear is used as a forward gear, which can automatically shift up and down.

Driving on the highway, D or S can be used, but it still depends on the specific situation of the scene. These two gears are best for patient use. Car owners who have been using S gear for a long time, if they feel that they are consuming fuel, they can also learn fuel-saving tips.

It is best not to slam on the accelerator or brake suddenly at high speeds, which will increase the wear and tear of the car and fuel consumption. The above is the answer to the question of why to use S gear or D gear for running at high speed.

Running high-speed with S gear, S gear belongs to the acceleration gear, try to use S gear to speed up in the high-speed section, D gear is just an ordinary forward gear, suitable for use in urban areas.

Use D gear, because it is more stable to run in D gear, once the car enters the highest gear, the S gear function will fail, which is unsafe.

When running at high speeds, you should use D gear; Because the D gear can better control the transmission, the D gear will be more stable at high speeds.

Under normal circumstances, when driving on the highway, if it is a constant speed cruising state, you should use the ordinary D gear, and you can completely go to the end. The characteristics of the S gear have been mentioned above, in fact, this gear is the most suitable for running at high speeds. Speaking of which, many people are worried about whether the S gear will be very fuel-intensive.

In fact, at high speeds, it is generally the highest gear, and the fuel consumption is the same in D gear. If it is not the highest gearbox, there is also a gear, but relative to the manual gearbox, the gear of the automatic transmission does not need to be operated manually, some gears are fixed, it has a fixed gear ratio, and some gears are not fixed, such as CVT gearbox, it does not have a fixed program to improve the engine response speed, if the power of the model itself is strong enough, there is no need to use S gear for high-speed overtaking, the legal speed limit of 120km h, more than you have to pay for it, It's useless to run even faster, if you talk about the model itself.

Under normal circumstances, you must use D gear on the high speed, and only in the case of overtaking, you will use S gear. Under normal circumstances, you must use D gear on the high speed, and only in the case of overtaking, you will use S gear. Through most people will only use D gear, other gears are rarely used, and they don't know their own car performance, the same car is driven by others The fuel consumption is relatively low, and the fuel consumption of their own is very high, in fact, it also has a certain impact on the gear.

I think I use D gear, anyway, I haven't used S gear on high speeds, but I used S gear when overtaking on the national highway, and there is a S gear when the D gear is wrongly turned into S gear, and D gear is used for normal driving, the so-called sports mode of S gear is that the engine pulls up the speed to bring high power output, and the fuel consumption is high when the S gear is running, I don't think it's necessary to use S gear, although the S gear is a sports mode, but when the higher the speed, the stronger the power, the higher the fuel consumption. Must use D gear, S gear can be overtaken or climbed to use, generally not recommended for long-term use, one is fuel consumption you can't stand, the other is wear and tear acceleration.

Of course, it is in "D" gear, because you need to drive all the way forward on the highway, and you don't need to be ready to brake with the engine at all times.

D gear is the forward gear, which is suitable for most road conditions; The S gear is a sports gear that is suitable for hill climbs and speeding. High-speed is generally driving at a constant speed, and most of them are smooth roads, so D gear is more suitable and can also reduce fuel consumption.

With D gear, the role of S gear is actually very simple, S gear can increase the speed of the engine, at this time S gear can be downshifted in advance and delay upshifting, so at this time, when the gearbox is in low gear, then the gearbox can reach more torque, so that the power of the car will be stronger. Therefore, it is suitable to use S gear in some road sections that are prone to lack of power.

Although there is data showing that people will buy automatic transmission cars when buying cars, automatic transmission cars are not as simple as we imagined, and they also need to switch gears during driving! Do you generally use S or D gear for high-speed driving? Old driver:

Such a simple question to ask!

The S gear is not for your daily use at all, and it costs more fuel to run high-speed and noisy travel, and you won't consider that fuel consumption when you need to use the S gear. BuyAutomatic.

It's just a picture of ease, D file.

That's enough. Overtaking with S gear, normal driving with D gear, the so-called sports mode of S gear is that the engine pulls up the speed to bring high power output, and the fuel consumption is high when running in S gear all the time.

1. Normally, D gear is used, but when you want to have good power, you want to experience the performance of the car when you use S gear.

Second, let's talk about the simple difference between these two gears.

The gear is the normal gear, and the general automatic transmission car will definitely have a D gear, but there may not be an S gear. Cheaper cars don't have an S gear. D gear is the normal gear, generally speaking, we use the most D gear when driving.

Take myself as an example, my car has an S gear, but I've been driving for a few years, and I rarely use it, and I've always used the D gear. The D gear is normal, and the turbocharger is driving slower.

It doesn't have to be involved in the work. At this time, it is relatively more fuel-efficient. But the power is also relatively normal, not as powerful as the S gear. Generally, we also have high-speed practical D gear in urban road sections.

The gear is the sport mode of the car, and some cars do not have an S gear, but they have a sport mode, which is the same. After the car is put into this gear, the turbocharger has been kept in working condition, which means that if you are driving in the city, sometimes the speed is slower and the turbo does not need to intervene, but when you are in S gear, the car only starts, and the turbo will always work. In this way, we can feel that the power will be much more abundant, and the fuel consumption will be relatively higher.

Therefore, under normal circumstances, I rarely use this stool gear. I use this gear unless I'm running on a mountain trail or when I want to experience the fun of staring while driving.

Finally, if I want to feel the driving pleasure, I use S gear at high speeds, and D gear when driving normally.

Running high speed should choose to use D gear, D gear running high speed is more fuel-efficient, and will not hurt the car, if it is always S gear special fuel consumption.

In general, D gear will be used more, because S is suitable for climbing or overtaking, so I think D gear will be more appropriate.

D gear should be used, and I personally think that this gear can ensure the running speed of the engine, and it can also play a role in fuel saving.

【Pacific Automobile Network】In normal driving, D gear is the best choice, economical and fuel-efficient, but it is best to switch to S gear when overtaking. The D gear will optimize the operation of the gearbox according to the driving conditions of the car, so that the car is more fuel-efficient, so the D gear is suitable for use at high speeds.

The manual transmission car has a more sense of operation, and is deeply loved by the old driver, but for the average person, its operation is still too cumbersome, and the operation is not proficient. Therefore, when buying a car, the simple and convenient automatic transmission is still liked by more people. However, it is too simple and not good, many car owners still can't figure out, private cars run high-speed with S gear or D gear?

9 percent of car owners are doing it wrong, and the fuel consumption of driving is doubled!

First of all, let's introduce the two gears, D gear is the driving gear, which is the gear used for normal running, and the S gear is the sports gear, which is equivalent to a high-performance mode of the car, in this state, the speed of the engine will increase rapidly, the air intake will increase, the car will be more powerful, the speed is fast, and it will respond to some oil, which is suitable for fast running. After reading these, let's go back to the original question, whether to use S or D gear for private cars to run at high speeds? Actually, it depends on the situation.

In normal driving, D gear is the best choice, economical and fuel-efficient, but it is best to switch to S gear when overtaking, the car is more fast, accurate and stable, the car speed is soft, and repeated attempts to fail will increase the incidence of accidents. When climbing, it is best to cut into S gear to get better torque and power, which can avoid the embarrassment of slipping as much as possible. Many cars have large displacement and turbos, and it is easy to overtake and climb without S gear, but the performance is not very good, in these cases, it is best to honestly hang on the S gear.

Of course, in the state of S gear, the engine temperature is high, wear and tear will be aggravated, it is very hurtful to hang the S gear all the time, and at the same time the amount of fuel injection increases, fuel consumption will also rise, 9 into the car owners often make this mistake, driving fuel consumption doubled. In addition, there are also car owners who want to hang the S gear to increase the speed when running at high speed, blowing the carbon deposits in the cylinder, which is actually useless, running high-speed cars become lighter, but the ECU adjusts the amount of fuel injection, and after two days the ECU re-adapts to the new environment, and the power is still weak.

Therefore, running high-speed hanging S gear does not have the effect of carbon removal, or go to the 4S shop to clean up, otherwise the accumulation is too much, not only the fuel is consumed, but the car will also have weak power when it is driving normally, and it will also produce cylinder bursting and shaking, which is to be ready to change the car. Of course, it is more expensive to go to the 4S shop to clear the carbon, and the engine has to be dismantled, which was originally for maintenance, but it was self-defeating and destroyed the car.
