Many people love to drive in 4D, and it helps to attain the maximum speed when you do not need to apply frequent brakes on highways.
What Does 4D Mean on a Car? 4D in a car means that you are driving in the highest fourth gear. The 4 represents the number of gears, and the D depicts that you are driving. It is beneficial to attain the maximum speed and drive in equilibrium conditions. You can shift your car into 4D while moving on highways at more than 30 mph speed. You can directly shift the transmission to 4D in winter to keep the engine warm and provide a smooth driving experience.
Nowadays, the latest cars are equipped with an automatic transmission system which is easy to use and less confusing. Moreover, it contains a shifter knob mentioned with numbers to shift the gears from high to low.

What is the meaning of 4D?
The different gears are present in automobiles to change the speed and give the wheels power according to these changes.
The shifting knob is present in automatic cars for the shifting of gears. These shifting knobs are mentioned in the higher to lower range.
The numbers like 1 to 4 are written on them to ease drivers during driving. 1 is the lowest gear shift, and 4 is the upper gear shift, while you can also engage the 5th and 6th during driving.
The 4D means driving in the 4th gear to attain the maximum speed. It shows that you drive in an equilibrium position after attaining the top speed.
You can see this on your dashboard, which shows that your automatic transmission is in fourth gear. The shifting knobs and levers are also mentioned with this number.
What are the uses of 4D on a car?
Many people love the automatic transmission because of less effort in shifting gears. However, there are several benefits of putting your car in 4D while driving.
Sometimes you want to move at high speed in case of emergencies and while going to the office.
You have to return home from the office or your working place when someone calls you or sends a text message.
You can shift your car from the less efficient 3rd gear to the highest fourth gear. It is beneficial to attain maximum speed during driving.
It is a safe driving position because the vehicle attains the maximum speed and provides the best mileage.
Smooth driving on highways
Highways are roads that are different from the normal ones. These are the broad roads with less traffic load, and you can drive freely there.
Many people want to drive their cars on highways while going for long-distance trips. Therefore, it is beneficial to adopt that road because it can save you time.
You will reach your destination in time and also saves gallons of fuel. People always drive at high speed on highways to save fuel and cover the maximum distance in minimum time.
You can put your automatic transmission into 4D and drive smoothly on highways. The engine gives the maximum power at this speed for smooth running.
The idling issues are also less because of the continuous supply of power. Smooth driving on highways is relaxing and comfortable for drivers and passengers because of fewer bumps.
It is better for highway driving because engine drag is less, and you must apply brakes less frequently on these roads.
Efficient use of gas
The efficient use of gas during driving is necessary to save fuel costs. However, not everyone can afford the high fuel cost and continuous refilling.
You should adopt reliable driving methods to save fuel economy and provide a better driving experience.
Many people complain that automatic transmission consumes more fuel due to advancements in features and the shifting of gears.
The frequent shifting of gears while driving cause the engine to burn more fuel due to changes in torque output.
You should use 4D gear it helps to improve your fuel efficiency. It keeps the RMPs in range and provides continuous power to attain the maximum speed.
It also provides the best fuel efficiency during uphill movement by keeping the RMPs higher.
Best for driving in towns
Due to its correct speed range, it is an ideal and suitable option for driving in towns and city areas. However, it is necessary to drive slow in a populated area.
The roads are full of traffic and pedestrians in the city area. Therefore, driving fast can increase the risk of accidents and collisions with other automobiles.
You should drive safely there and with full attention to minimize accidental cases. The accident will ultimately increase the repairing cost of your car.
You need continuous power from the engine and high RMPs. It is only possible when you shift the transmission into 4th gear.
You can drive without stalling issues because of the continuous power supply.
However, it is better to move at D3 in the city area and shift towards D4 when driving fast on highways.
The engine warms up faster in cold
The low outside temperature makes the engine cold in the winter season.
The stalling occurs due to oil viscosity and freezing of fuel lines. You can try the jump start method for proper and quick ignition, but it is harmful to engine parts.
You should use your vehicle in 4D because it keeps the engine cold in the winter season. As a result, you do not face stalling issues or jerky rides when you turn on the ignition switch.
The 4D means the engine supplies power continuously and maintains the equilibrium. It keeps the equilibrium at high revolutions per minute.
How do you put your car in 4D?
The automatic transmission in automobiles is connected to the onboard computer system. The computerized system detects the optimum revolutions per minute of the engine.
The transmission automatically shifts towards the higher gears like 4D, 5, and 6 when the engine has high RMPs.
The transmission is shifted towards the lower gears like 1 or 2 when the engine’s RPMs are low.
Release it after gaining the minimum speed, and it is better for uphill movement because you need more power from the engine.
The engine does not have to work harder for downhill movement. Therefore, you should not press the gas pedal while downshifting and relax the pedal for shifting towards lower gears.
Is 4D the same as 4WD?
4D or 4WD look similar, but these are different terms and have different functions. For example, 4D is the feature of the automatic transmission system, while 4WD is associated with the movement of wheels.
4D means moving in the highest fourth gear and at high speed. 4WD depicts that all tires will spin at the same speed while receiving power from the engine.
It engages all wheels while moving challenging roads and decreases the chances of slipping and rolling.
4WD is better for safe and comfortable driving on snowy roads. This is because the engagement of all wheels during driving maintains traction and control on the road.
You can drive better on off and slippery roads in the snowy season.
What is the maximum speed in 4D?
4D is best for driving at the slow speed of 25kmp/h to 30kmp/h in a city and populated area. You cannot feel the stalling issue at this slow speed because the engine provides high RMPs.
It is the highest gear and a suitable option for driving on highways.
You can drive fast on highways with constant power from the engine. The maximum speed you can attain in 4D on the highway is about 30 mph.
Can you go from 1st to 4th gear?
It is safe to skip gears during upshifting and downshifting.
Many of my friends who use automatic cars said they directly come from 2nd to 4th.
It is not damaging to any components, and you can also safely do this. The problem comes when you do this frequently while moving on highways.
The wear and tear in a component in transmission components and gears occur due to frequent up and downshifting.
The option of skipping gear is also present in the modern manual transmission.
What do car drivers say about this?
I surveyed about 609 American drivers who have automatic cars to take their reviews about the driving experience on 4D.
Out of 609 drivers, 497 (82%) said that it is best to increase the car’s speed when moving on highways.
Fifty-three drivers (9%) said they use this gear because it saves fuel economy by keeping the speed and revolution per minute at the maximum rate.
However, the remaining 59 (9%) people said D3 is best for city driving, and you can use it only on highways to attain high speed.
One of the car drivers said: “I prefer to keep my car in 4D when I drive on highways because it can maintain the maximum speed and provide good fuel efficiency”.
Stalling is a common issue when you drive at low speed in city or town areas because of fewer revolutions per minute.
The other driver mentioned: “I use the 4D in city areas because there is no stalling issue at the speed of 33kmp/h”.
Driving in hilly areas is calming and relaxing, but it seems adventurous because you can get confused while shifting transmission.
The third driver said: “I need high speed while uphill movement and keep pressing the pedal to put my automatic transmission into 4D”.
