BMW automatic transmission car on the highway has been using comfort mode okay

At present, the E-class of Beijing has been replaced, and the new car is about to be launched in Germany. If it is made in China, it will have to wait until at least next year, because Mercedes-Benz will introduce an extended version at that time. The power of the 523Li is better than that of the E230, after all, BMW's inline 6-cylinder is not in vain, it runs smoothly and has good power performance.

Paired with a 6-speed automatic manual transmission, the BMW 523LI has an excellent driving performance. Mercedes-Benz comfort has always been excellent, and even if the E230 is being replaced, its comfort is still better than that of the BMW 5 Series and Audi A6Therefore, if you are not clear about your specific requirements, it is really difficult to say which one to choose.

However, it can be judged from the following aspects. E230 curb weight of 1660 kg, official fuel consumption of 100 kilometers, the engine uses, maximum horsepower 204 horsepower, with 7-speed manual automatic transmission, excellent driving comfort. BMW 523li curb weight 1630 kg, official fuel consumption of 7 liters 100 km, using in-line 6 cylinders, maximum horsepower 177 horsepower, using a 6-speed automatic manual transmission.

So, in terms of power, Mercedes-Benz is superior. In terms of space, the space of the 523Li (4981 1846 1477, wheelbase 3028mm) is significantly better than that of the Mercedes-Benz E230 (4856 1822 1483, wheelbase 2854mm). It's clear that the 5 Series space is better than the E-class.

In terms of safety configuration, the 523Li lacks rear side airbags, the E230 lacks knee airbags, seat belt unfastened prompts and keyless start system, and the rest is the same. In terms of comfort configuration, both cars are the lowest configuration models, and the configuration of higher configuration models is much less. In terms of internal configuration, the 523LI has more cruise control than the E230; In terms of seat configuration, the E230 has more lumbar support adjustment than the 523Li, but the E230 does not have rear seat heating.

The rest of the equipment is the same for both vehicles. In terms of multi** control, E230 can be equipped with optional GPS, and it is equipped with a car TV, while BMW 523Li does not. However, the 523Li internal hard drive is not available on the E230.

On the air conditioner, the E230 has more air conditioning than the 523Li pollen filtration, and the rest is the same. In general, the configuration of the two cars is much the same. However, there is a large gap.

The 523LI manufacturer's guide price is 10,000, the E230 manufacturer's guide price is 10,000, and the E230 is much more expensive. Finally, my advice to you is that if you are looking for comfort and a relaxed drive, the E230 bar. If you pursue dynamics, like to drive, and have requirements for handling performance, 523li bar.

And you can save 80,000 yuan!

No, you can't:

1: L gear is a low-speed gear, the speed ratio on the highway is not enough, and the loss of the continuously variable transmission is very large 2: There is a minimum speed limit on the highway, then you need to increase the throttle, and the fuel consumption will be very high 3:

The engine is in the case of low speed and high speed for a long time, and the water temperature is easy to be high, and the crankshaft and size tile are damaged.

l When it is a low-speed driving climbing gear, it cannot be used for high-speed driving, which will cause the transmission to overheat and burn out.

It's best not to use the D gear, but to use the L downhill

Hello, if you keep the sport mode, the fuel consumption will be higher, and it will have no effect on the car. In the long-term energy-saving mode, the engine may have a little more carbon deposit.

If you look like this car, whether you drive in eco mode or sport mode, it will not cause damage to the engine, this will only cause the fuel consumption of the engine to change, and nothing else will matter.

This will not have any effect on the station, but it would be better to use the energy saving mode as much as possible, if the engine speed is higher after using the sport mode, it will increase the oil consumption, and it will also consume more fuel.

Hello, the sport mode of the car, the power is relatively strong, of course, the fuel consumption is higher, the energy saving mode, the power is average. Fuel consumption is also low, it is recommended to use the energy-saving mode frequently, and it is still more economical and practical for general urban roads.

Keeping the sport mode in place will speed up the life of the engine.

You can use it all, isn't it too good.

Hello Comfort mode stability is better Sport mode is more inclined Power Torque Thank you for your support to the car master [If you have a question about the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, definitely the stability of the comfort mode is better, [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

It's okay, but don't switch too fast.

Manual Transmission (MT) Manual transmission, also known as manual transmission, is to change the gear meshing device in the transmission by toggling the gear lever by hand, and change the transmission ratio, so as to achieve the purpose of shifting.

The pump wheel and the turbine are a pair of working combinations, they are like two fans placed oppositely, the wind force blown by one fan will drive the blades of the other fan to rotate, and the wind force has become the medium of kinetic energy transmission, if the liquid is used instead of air to become the medium of kinetic energy transmission, the pump wheel will drive the turbine to rotate through the liquid, and then add the guide wheel between the pump wheel and the turbine, and the speed difference between the pump wheel and the turbine can be realized by the reaction force. Because the range of automatic transmission torque change of the torque converter is not large enough, several rows of planetary gears are connected in series behind the turbine to improve efficiency, and the hydraulic control system will operate the planetary gears by itself with the change of engine work, so as to achieve automatic variable speed and torque change. The auxiliary mechanism automatic shift can not meet a variety of needs on driving, such as parking, reverse, etc., so it is also equipped with an intervention device, that is, a manual lever, and the signs P (parking), R (rear gear), N (neutral), D (forward), and also in the forward gear"2"with"1"for starting or climbing slopes.

Since its transmission area is divided into several gear-ratio sections, which are infinitely variable only within the specified transmission section, the AT is actually an automatic transmission between stepless and stepless. Advantages and disadvantagesAT does not use the clutch to shift gears, the gear is less and the change is large, and the connection is stable, so it is easy to operate, which not only brings convenience to the driver, but also brings comfort to the passenger in the car.

Hello, the manual mode and automatic mode of the automatic manual transmission can be switched at any time.

The automatic manual transmission only adds an artificial shift function to the automatic transmission, and its power transmission route in manual mode is exactly the same as that in automatic mode.

Yes, it can be switched! There is no need to step on the brakes, the number of gears of the automatic transmission is corresponding to the manual one, so don't be careful!

There is a relationship between rotational speed and speed.

Driving is for smooth and comfortable exercise. Not advocated.

Sport mode is to increase the power of the engine in a short period of time, to achieve the effect of instantaneous acceleration, simply put, acceleration gear, climbing gear, overtaking gear, with sports mode, the speed will increase sharply, about 800-1000 rpm or so, fuel consumption will also increase at any time, so this gear is generally not used, unless you pursue speed more, remember one point, do not use sports mode when starting, it will be very bad for the engine, remember!

How to use the automatic manual mode correctly? In these cases, manual mode is safer.

S gear, refers to the sports mode When this button is pressed, the timing of the shift of the "D" gear will also change, and the automatic change of gear will be carried out in the area of higher engine speed, so the power of the car is more thorough. However, when using the "S" button to turn on the sport mode, unlike using "Limit", it only adjusts the timing of the gear shift, but does not limit the gear shift, so there is no over-speed operation of the engine. The sporty features and style of the "S" button are generally suitable for drivers who like to accelerate quickly, but fuel consumption will increase when starting this function.

It is mainly used for running mountain roads, and it will also be used for a small biao on the highway.

It is the sport mode of the car S gear (S stands for Sport).

In the S mode of sport, the gearbox can shift gears freely, but the opportunity is delayed when shifting, so that the engine can be kept at high rpm for a longer time, and the large torque is output immediately, so that the vehicle power is increased. Generally speaking, ordinary automatic transmission or CVT models will keep the rev at about 2000 rpm, while S gear can delay the shift time until the engine is running at its best, and if it is a vehicle with paddle shifters, it will kill all the way to the rev red zone.

When using the S gear, the amount of fuel injected into the engine changes due to the increase in speed, and the force increases. At the same time, the suspension has become stiffer than usual, so that the roll is reduced when cornering and the brakes are less nodding. Of course, the comfort is worse in S mode.

It is used when running on mountain roads or in drag racing.

It is true that too low a speed can easily cause carbon deposits. First: Fill high-quality gasoline Impurities such as wax and gum in gasoline are the main components of carbon deposits, so the trend of carbon deposits in gasoline with high cleanliness is weaker.

Unfortunately, at present, the quality of gasoline in China is still low compared with developed countries, and it can only be simplified because of ugliness. It should be noted that high grade does not equal high quality, that is to say, the oil of No. 97 is not necessarily less impurities than that of No. 93, and the label only represents the octane number of the oil, not the quality and cleanliness. In order to ensure the cleanliness of gasoline, some car owners will adopt the practice of adding gasoline detergent to gasoline.

This can effectively prevent the formation of carbon deposits on the metal surface, and can gradually activate the original carbon deposits and slowly remove them, so as to protect the engine from damage. However, the addition of gasoline detergent must be cautious, if you add shoddy products, you will get the opposite effect. Second:

Don't idle for long periods of time The longer the idle time is, the longer the engine reaches normal temperature, and the slower the rate of evaporation of gasoline when it is injected into the back of the valve, which creates carbon deposits. At the same time, if you are driving at idle speed, the air flow into the engine will be small, so the scouring effect on carbon deposits will also be weak, which will promote the deposition of carbon deposits. Third:

Run more high-speed and increase the speed as much as possible The purpose of running more high-speed is to use the scouring effect of the air flow on the intake tract to prevent carbon deposits. In addition, increasing the speed of shifting gears is also similar to running at high speed, turning the original gear shift at 2000 into 2500 conversion, which can not only effectively prevent the generation of carbon deposits, but also improve the dynamics of the car, and also avoid the detonation caused by too low shift speed and protect the engine. Nowadays, many automatic transmission models also have a manual mode, which can be used to downshift reasonably to increase the rpm.

It's all automatic.

The gear order for Audi is p n d s

BMW is automatically going back,Pull back is D gear,There is a button on it to press down is P Mercedes-Benz is an American bosom gear,Backward is D,P block is pressed on the side and it is written very clearly,I understand it at a glance。
