Now the mainstream sedan is front wheel drive or rear wheel drive

Pre-drive and rear-wheel drive. And doesn't say anything!!

The key is that he didn't really reflect their respective advantages!

Wisdom is a rear-wheel drive car, but he can't do it at all!

On the contrary, it is her shortcomings!

In addition to buying a high-end car.

Or buy a front-wheel drive car with relatively mature technology!

There are many front-wheel drive, and there are quite few rear-wheel drive except for high-end cars.

Cheap front-wheel drive Expensive rear-wheel drive.

Front-wheel drive is more rear-wheel drive is generally a high-end car.

Most of them are prodromal, accounting for a large proportion.

Most of the mid-to-high-end ones are front-wheel-drive.

The most advanced is the rear drive.

The power distribution mode of front-wheel drive is that the engine only drives a pair of front wheels, and the power distribution mode of rear-wheel drive is that the engine only drives a pair of rear wheels. The drive shaft of the front-wheel drive does not need to pass through the cockpit and does not need to make the rear axle housing, the transmission and differential are assembled in a single housing, the drive shaft of the rear-wheel drive needs to pass through the cockpit, and to make the rear axle housing, the transmission and differential are assembled separately.

Front-wheel drive or rear-wheel drive can only be analyzed according to the use of the vehicle, and there is no absolute good or bad. Front-wheel drive is suitable for flat roads, acceleration can be well improved, and handling is stable. Rear-wheel drive can be used on mountain roads or off-road, and front-wheel drive is unbeatable in terms of load.

Front-wheel drive takes the most common front-wheel drive as an example, which is also the most common arrangement on family cars, the so-called front-wheel drive, which means that the engine is in the front of the vehicle, and the front wheels of the car are responsible for both steering and driving at the same time. The most obvious advantage of the front wheel drive is that there is one less transmission shaft in the structure, which not only saves costs, but also saves fuel to a certain extent due to its light weight. Secondly, without the power transmission of the propeller shaft, the front-wheel drive will be better in terms of transmission efficiency.

In terms of space, without the influence of the arrangement of the drive shaft, the floor of the rear row can be more easily flat, improving the comfort of the ride. With advantages comes disadvantages, and when the vehicle reaches the uphill section, the vehicle's climbing ability is worse than that of rear-wheel drive due to the center of gravity. In terms of handling, front-wheel drive will also have the problem of understeer, which is what we often call pushing.

Rear-wheel drive is also an example of the common front-wheel drive, the front wheel is responsible for steering, and the rear wheel is responsible for driving, which can reduce the burden on the front wheel. Secondly, because the weight distribution is relatively uniform, it is conducive to the chassis engineers to better play their advantages when doing calibration, and the rear-wheel drive car will not be bad in terms of handling and stability, and the ability to climb hills will be better. However, the arrangement of the propeller shaft will inevitably affect the space, fuel consumption and transmission efficiency.

In terms of handling, although rear-wheel drive cars have advantages over front-wheel drive, there will also be oversteer, that is, tail flick.

Problem description: Is it easier to steer with rear-wheel drive? Or front-wheel drive steering is easy.

Analysis: The top floor is copied from somewhere, the front drive is much cheaper than the rear drive, so why are the cheap cars using the rear drive method?

Yes, rear-wheel drive vehicles steer more easily than front-wheel drive vehicles. Since it is front-wheel drive, the force on both front wheels is the same, and it takes a lot of force to make it change direction when changing direction. The driving wheels of the rear-wheel drive car do not affect the change of direction of the front wheels in the rear, so the rear-wheel drive car can be maneuverable flexibly and can be used as you like without the power steering assist system.

Today's front-wheel drive vehicles are generally equipped with power steering assistance systems to solve the problem of poor handling.

The advantages of a front-wheel drive car in the case of the same displacement are:

The effective output kinetic energy is high, the fuel consumption is low, the power is strong, the volume is small, the interior space is large, the vehicle is lightweight, the structure is compact, the failure rate is low, and the driving speed is high.

Disadvantages of front-wheel drive cars: (This is exactly what you want to know).

Complex structure, high machining accuracy, high manufacturing cost, high maintenance process requirements, poor bearing capacity, poor control performance and other shortcomings.

These advantages and disadvantages of the front-wheel drive car determine that it is used in small cars with high needs and large space needs.

The advantages of a rear-wheel drive car are:

It has the advantages of good bearing capacity, simple structure, convenient maintenance and good control performance.

The disadvantages of rear-wheel drive cars are:

Large volume, high quality, high and slow driving speed, high fuel consumption, high failure rate and other shortcomings.

Therefore, rear-wheel drive vehicles are only used for large and medium-sized freight and passenger vehicles with large volume and large cargo capacity.
