What do you mean by front and rear drive?

Front rear wheel drive is the common name of automobile drive form, that is, engine front rear wheel drive, which is the most traditional drive form.

Usually, a car has a front wheel and a rear wheel, which are directly driven by the engine, so it is the driving wheel that drives (or pulls) the front wheel of the car. The most commonly used driving modes in automobiles are front drive, front and rear drive and full-time four-wheel drive.

According to the number of driving wheels, it can be divided into two categories, two-wheel drive and four-wheel drive. According to the position of the engine in the car and the position of the driving wheels, two-wheel drive can be divided into four forms: front and rear drive (FR), front and rear drive (FF), rear and rear drive (RR) and central rear drive (MR).

Distribution form

The advantages of front drive are compact structure of power system, short drive shaft and low power output loss. In terms of handling, front-wheel drive is inherently understeer and easy to drive. Its disadvantage is that it will reduce the front axle load when starting, which will lead to the decrease of tire adhesion and affect the power output. In addition, the front wheel is responsible for driving, steering and most of the braking force, so the wear is serious.

Front rear wheel drive is just the opposite. Its advantage is strong starting acceleration, even four-wheel load. But its disadvantage is that it is easy to oversteer when turning, which requires good technology or advanced electronic equipment. So most racing cars are still driven by rear wheels. In terms of handling performance, the most ideal arrangement is the rear wheel or four-wheel drive of the central engine.
