What's the difference between front drive and rear drive? Which is better?

The difference between front-wheel drive (FWD) and rear-wheel drive (RWD) is whether it is driven by the front wheel or the rear wheel. Is the image point the front wheel? Drag? Running with the car or the rear wheel? Push? Run with the car.

Adults should not only look at things in a simple binary way, but also evaluate things in a dialectical way. First of all, let's talk about the advantages of the front drive: 1. The front drive is more stable in a straight line. This is easy to understand. Imagine a trolley in a supermarket. When it is full of purchased goods, it often tilts when pushed, especially for children. And it's easier to walk out of a straight line if you are pulling in front. 2. Less loss in the process of power transmission. Because the front wheel is close to the engine and gearbox, the transmission distance is short, so the wasted kinetic energy is the least. 3. Simple structure and light weight. The power system of the car is all concentrated in the front, and there is no need for complicated machinery and circuits to run through the front and rear bodies, which can save a lot of manufacturing costs and weight. Therefore, almost all the low-priced cars we see are predecessor designs. 4. Save the space inside the car. Because the front-drive cars are generally transverse engines with compact structure, the space requirements for the engine compartment are small, and all the saved space can be reserved for the use in the car. In this way, the space in the car is more spacious and more suitable for families. In addition, because there is no main transmission shaft, there will not be a raised channel on the center line of the floor inside the car to split the car in two.

disadvantages of the front drive: 1. Because all the power systems and transmission mechanisms are concentrated in the head, the center of gravity of the whole vehicle is forward and the handling is poor. 2. When starting and accelerating, the center of gravity moves backward, and the adhesion between the front wheel and the ground will be reduced, which makes it easy to slip. 3. When braking, the center of gravity moves forward, and the vehicle will? Nod? , passengers in the car? Rush? The feeling. 4. When cornering, the front wheel bears both driving and steering, and the driving force is easy to break through the adhesion, resulting in insufficient steering. Push your head? .

let's talk about rear-wheel drive, which also has advantages and disadvantages. Advantages of rear-wheel drive: 1. Because the engine is vertical, and the transmission mechanism doesn't have to be completely arranged at the front of the car, there is enough space for modeling design to obtain excellent appearance and drag coefficient. 2. When starting and accelerating, the center of gravity moves backward, and the adhesion between the rear wheel and the ground will increase, so it is not easy to slip and the acceleration performance can be improved. 3. Because the power system is evenly distributed in the front and rear, the center of gravity of the whole vehicle can be in the middle of the vehicle, which is conducive to improving maneuverability. 4. The front wheel is responsible for steering, and the rear wheel is responsible for driving, and each has its own duties. The steering is more accurate and it is not easy to understeer.

disadvantages of rear-wheel drive: 1. The linear directivity is slightly poor, also refer to the example of supermarket cart. 2. The transmission loss is large, because the transmission distance is long, there are many transmission links, the transmission system is more complicated and the construction cost is more expensive. 3. unfriendly to novice drivers, once the rear wheel driving force is too large, it is easy to oversteer. Flip your tail? Or? Drift? . 4. Due to the complicated and long-distance transmission system, the weight of the whole vehicle is increased. By analyzing the advantages and disadvantages of front drive and rear drive, we will find that we can't use which one is better to evaluate front drive and rear drive. If you have a high demand for interior space, and the car is only used to pick up and drop off children and commute, driving before is a more economical and intimate choice. If you have a great demand for car handling, and you are an out-and-out car-playing party, then rear-wheel drive is more suitable for you.
