What are the advantages and disadvantages of front wheel drive and rear wheel drive

Cars were first rear-drive, and now trucks are still rear-drive, which does not represent advanced and advanced.

In the 80s, sedans moved from rear-wheel drive to front-wheel drive, which was a big step forward. Why didn't the cars of the past use front-wheel drive?

The biggest advantage of a front-wheel drive car is that the floor is lowered, which increases the space and makes it easy to arrange.

The second advantage is the improved comfort. When encountering an obstacle, such as a brick, a small stone, a pipe, the front drive wheel is easy to cross, the rear wheel is easy to drag over, without deceleration, the rear drive car, the front wheel has no driving force, it will play a "brake" effect, the instantaneous speed reduction, the stability of the car speed is destroyed, and the person who sits in the car will "lean forward and close".

In addition, it also saves raw materials, saves drive shafts, etc., which saves costs and can make the car cheaper.

There is a more important reason: the driving wheels must be heavy on the load-bearing axle, and the car is mainly the engine and other metal lumps, so in general, the front axle is the main load-bearing bridge, unless there is an extra-large fat man sitting in the back seat, and the luggage compartment is used to pull the iron block. Load-bearing axles should be driven axles, and the reason for this goes without saying.

So why didn't the cars of the past use front-wheel drive? There are two main reasons for design and manufacturing.

Front-wheel drive car, must be transverse engine, the engine should be placed vertically, and then the power goes around to the front, like the transfer case of a jeep, there are many difficulties, and the cost of materials, the cost will inevitably rise. To transverse engines, the engine must be designed to be compact, and this compact engine is difficult to design and arrange without computer-aided design.

Even if it's designed, it doesn't make much sense. Because of the low level of manufacturing and the high failure rate in the past, a car had to be repaired constantly, just like today's trucks. It is unthinkable that a compact engine is very difficult to repair, and it is unthinkable to remove a lot or even all things to touch the parts to be repaired, so before the manufacturing level is improved, the engine compartment needs space for repairs, and it is impossible to make it so compact and stuffed.

After the progress of science and technology, computer-aided design makes it easy to arrange compactly, and at the same time, the manufacturing level has also been improved, the engine can be trouble-free for a long time, and the new car does not need to be repaired for several years, and the durability is guaranteed, which makes it possible to have a front-wheel drive. Hence the precursor that became popular.

Now the engine of the van is crudely made, the failure rate is high, and the engine still needs to be in line to free up room for maintenance and repair. Since the center of gravity is in the rear compartment, rear-wheel drive is a must.

The front wheel drive of the car also has serious disadvantages, that is, when going uphill, the center of gravity is on the rear wheels, but the rear wheels are not the driving wheels, and the powered front wheels are not strong, which is very unreasonable. When the rear-wheel drive car goes downhill, although it also has such a problem, it does not have much impact, because it does not need much power to go downhill, and the rear wheels do not need to eat much.

In general, the front wheel drive and the rear wheel drive have their own advantages and disadvantages, and it makes no sense to simply say which way is better.

Note: It's not my answer, it's someone else's.

I think it's better to have rear-wheel drive

The advantages and disadvantages of front drive and rear drive are as follows: The advantages of the precursor are: the power system is compact, the transmission shaft is short, and the power output loss is small.

In terms of handling, front-wheel drive is inherently understeered and easy to drive. In terms of layout, there is no propeller shaft through the body, which can reduce the bulge in the middle of the body and increase the empty space of the car. Disadvantages of the precursor:

When starting, the load on the front axle is reduced, resulting in a decrease in tire adhesion and affecting power delivery. Coupled with the fact that the front wheels are responsible for driving, turning the sail and most of the braking power, the wear is severe. Advantages of rear drive:

Rear-wheel drive is common in supercars. The advantage of the sock car is that the front and rear weight ratio of the vehicle is close to perfect, taking into account the advantages of the front and rear drives, but there is no transmission loss like the front and rear drives. Disadvantages of rear drive:

Rear-wheel drive cars often leave large bumps on the floor inside the car because the power wheels are in the back. Affect rides. Quick cornering makes it easier to drift.

It is also easy to oversteer. In addition, rear-wheel drive does not grip as well as front-wheel drive on ice and snow roads, and cannot go uphill.

The advantages and disadvantages of front-wheel drive and rear-wheel drive are as follows: 1. The advantages of front-wheel drive are: compact power system, short drive shaft, low power output loss.

In terms of handling, front-wheel drive cars are inherently understeer and easy to drive. In terms of layout, there is no propeller shaft passing through the compartment, which can reduce the bulge in the middle of the body and increase the usable space of the compartment. 2. Disadvantages of the precursor:

At the start, the load on the front axle is reduced, resulting in reduced tire adhesion and affecting power delivery. In addition, the front wheels are responsible for the drive, steering and most of the braking power, so the wear is severe. 3. Advantages of rear drive:

Rear-wheel drive is generally found in supercars. The advantage is that the front-to-rear weight ratio of the vehicle is close to perfect, and it takes into account the advantages of front-rear-wheel drive vehicles, but there will be no transmission loss like front-rear drive vehicles. 4. Disadvantages of rear drive:

Rear-wheel drive vehicles often leave large bumps on the floor of the car because of the power wheels in the rear. Affect the ride. Quick cornering makes it easier to drift.

It is also easy to oversteer. In addition, on ice and snow roads, the grip ability of the rear drive car is not as good as that of the front drive, and it is impossible to climb uphill.

Front drive and rear drive are 2 different forms, there is no better or more advanced than which one, each has its own advantages and disadvantages, we need to combine our own actual car needs to choose, it is the most reasonable.

1. Advantages of predrive:

The power system is compact, the drive shaft is short, and the power output loss is low. In terms of handling, front-wheel drive cars are inherently understeer and easy to drive. In terms of layout, there is no propeller shaft passing through the compartment, which can reduce the bulge in the middle of the body and increase the usable space of the compartment.

2. Disadvantages of the precursor:

At the start, the load on the front axle is reduced, resulting in reduced tire adhesion and affecting power delivery. In addition, the front wheels are responsible for the drive, steering and most of the braking power, so the wear is severe.

3. Advantages of rear drive:

Rear-wheel drive is generally found in supercars. The advantage is that the front-to-rear weight ratio of the vehicle is close to perfect, and it takes into account the advantages of front-rear-wheel drive vehicles, but there will be no transmission loss like front-rear drive vehicles.

4. Disadvantages of rear drive:

Rear-wheel drive vehicles often leave large bumps on the floor of the car because of the power wheels in the rear. Affect the ride. Quick cornering makes it easier to drift. It is also easy to oversteer. In addition, on ice and snow roads, the grip ability of the rear drive car is not as good as that of the front drive, and it is impossible to climb uphill.

Front-wheel drive and rear-wheel drive models

1. Front-wheel drive representative models: Volkswagen Magotan, Passat, Golf, Toyota Camry, Audi A3, etc.

2. Rear-wheel drive representative models: BMW, Jaguar, Koenigsegg, Pagani, Aston Martin, etc.
