From a financial perspective, the manufacturing cost of front-wheel drive cars is usually lower than that of rear-wheel drive cars, and the entry threshold is also lower. This is also the main reason why most A-class cars and mid- to low-priced B-class cars are front-wheel drive cars. reason.

Compared with rear-wheel drive vehicles, front-wheel drive vehicles usually integrate transmission structures such as the main reducer and differential into the gearbox, and also eliminate the need for a drive shaft to the rear wheels, resulting in higher power transmission efficiency. , The car body is lighter and more fuel-efficient. Extended information

Advantages of front drive

The driving wheel is very close to the engine, which directly makes the transmission distance short, simple structure, light weight and low cost. Since there is no need to transmit power to the rear wheel, Without the transmission shaft that runs through the entire vehicle, the intuitive reflection inside the vehicle is that the middle protrusion in the rear row will become smaller and the space will be larger.

At the same time, due to various reasons, the engine compartment of front-wheel drive cars is shorter, which can leave more space for the cockpit. This is why there is often a gap in the interior space between two cars with the same wheelbase. reason.

Disadvantages of front-wheel drive

All transmission components and engines are concentrated at the front of the car, causing the front and rear weight distribution of the vehicle to be uneven, and understeer is likely to occur when the front of the car is overweight;

Because the engine is in the front, it is impossible to install a transmission half-shaft of exactly the same length. Torque steering will occur when driving. This term may be difficult to understand. The intuitive manifestation is that when accelerating, the vehicle will tend to turn on its own. , the stronger the power, the more obvious the trend; the front wheel assumes the tasks of steering and driving at the same time, which will increase the wear of the front wheel.
