Learn the difference between 4WD, AWD, FWD, and RWD

Driving systems vary with different cars. Each car company puts in its car the optimal system for it, which helps it to carry out the tasks for which it was made. SUV cars, for example, are made with AWD or 4WD all-wheel drive.As for Berlin cars, for example, they come either with front wheel drive (FWD), which is very common, or with rear wheel drive (RWD), which you often find in American cars.What is the difference between these systems? What are the pros and cons of each system?

First: AWD system:

And the all-wheel drive system is a system that allows the four wheels of the car to always work, and this system helps in driving in difficult terrainOFF-ROAD Companies manufacture their cars for difficult terrain, so we find it, jeeps, etc. However, this system has drawbacks, as is the case in all the systems that we will discuss. This system increases the weight of the car, which directly leads to slow acceleration of the car compared to other systems, and it also increases fuel consumption to always operate the four cars, and all-wheel drive cars are Slow acceleration, due to the distribution of the car’s power to the four wheels, which increases the timing of acceleration, for exampleWe take a Toyota Land Cruiser with 250 hp. When we distribute 250 hp to the four wheels, it gives us 62.5 hp per wheel. If we take a Toyota Avensis 126 hp front-wheel drive car and distribute the power to the two wheels, we get 63 hp per wheel, which is in the interest of the Avances, Overweight as well.

Second: the four-wheel drive system 4WD:

The four-wheel drive system, like all-wheel drive, is a system intended for difficult terrain as well, but what distinguishes it from the latter is the separabilityWhat is separability? Separability means that the car can separate the four-wheel drive system and operate with only two wheels instead of four in the case of normal roads, which is a smart way to save fuel. Some cars separate the car’s computer alone, the power from the two rear wheels, for example, when it feels that you do not need it, for example, while driving in the city, and restarts it in case it feels that there is difficulty in moving the car in difficult terrain. dedicated to it.As for its downsides, it also consumes relatively more fuel than the front and rear drive systems, as well as the extra weight, which increases the car’s acceleration.

Third: Front wheel drive system FWD:

The front-wheel drive system is a system that makes the engine distributes power to the two front wheels only, and it is one of the practical and most prevalent systems currently in economic and practical cars, due to its multiple advantages.It is easier than pushing from the rear, which gives an advantage compared to other systems in terms of acceleration, and it is also more economical because the engine is closer to the front wheels than to the rear wheels. This is why, as we mentioned, we find it more in economic cars.However, it is also not free from the disadvantages of the difficulty of steering when starting fast in a race, for example, DRAG-RACE, due to the thrust force that puts pressure on the front wheels, the impossibility of drifting, and the ease of breaking it because it cannot bear difficult terrain and bumps, etc.

Fourth: RWD rear wheel drive system:

The rear-wheel drive system is a system that relies on the drive from the rear wheels, and it is the most loved system by car enthusiasts because it provides ease in performing acrobatic movements in the car. We find this type of propulsion a lot in German and American cars and some fast cars because of its many advantages. It is considered to be harder than the front-wheel drive system in terms of endurance and lack of faults, but it is not without drawbacks, as it is less erratic than other systems in curvatures, especially as the car may go off its track, which is The so-called over steer which will be our next topic.

The bottom line is that before buying any car, we must first know the reasons for buying the car, the way I will drive and the tracks I will drive on. Lovers of sneezing and reckless driving and a lover of mechanics and speed, I advise you on the rear-wheel drive system, as it will quench your thirst for adventure, but if you are driving on a difficult road always and the difficult road overcomes the flat road, I advise you to AWD all-wheel drive. If you live in the city and rarely go to adventure in the deserts or forests, I advise you Pal 4WD it will definitely suit you.
