Front wheel drive advantages and disadvantages

Front wheel drive advantages

First, it can reduce the cost of the car, which is why many car manufacturers today use this drive system. Front wheel drive (FWD) is much cheaper to manufacture and install than rear wheel drive (RWD). It does not pass through the drive shaft under the cockpit, nor does it make the rear axle housing. The transmission and differential are assembled in a single housing, which requires fewer components. This front-wheel drive system also allows the designer to more easily install other components on the bottom of the car, such as the brake system, fuel supply system and exhaust system.

Reducing the weight of the entire vehicle is another advantage of front-wheel drive. Reducing the weight of the car can improve acceleration, braking and fuel economy. Since the driving wheels of the front-wheel drive car bear the weight of the engine and the drive axle, the adhesion of the drive wheels can be increased, which will be of great help to cars traveling on slippery roads.

The biggest advantage of front-wheel drive is that it can have a large indoor space, and the cab does not have a large bump due to the passage of the drive shaft. Take a look at the Honda Civic, you will find that this car can also have a rear seat space that many cars can't match, because there is a flat bottom plate, and there is no rear differential, the luggage space is also Will get bigger.

Front wheel drive disadvantage

The main disadvantage of front-wheel drive is that the handling of the car is degraded. Because most of the mass is concentrated in the front of the car, the rear of the car will become lighter, so that the adhesion of the rear wheel will become smaller, and it is easy to travel on the road covered with ice. Skid. However, this problem has been solved. The designer will set the weight as much as possible at the back of the car. The ideal mass distribution is the ratio of the mass of the front and rear wheels to 50:50, but the front-wheel drive car. Few have reached or approached this ratio.

Another disadvantage is the load on the front wheels. The front wheels must transmit acceleration, the forces acting on the tires when steering and braking. Tires have limited adhesion, and when part of the adhesion is used to accelerate, it will definitely reduce the force on other parts. The rear wheel is not able to withstand this force, it only needs to follow the front wheel to roll.
