There are various kinds of drive systems in cars with every difference in them. Usually it is also called Wheel Drive or a wheel drive system which functions to distribute power from the tires to the road so that the car moves. The engine will distribute the torque optimally to make the tires move forward or backward.
What Are The Drive Systems In Cars?
This 2WD uses a drive mode system that only uses two wheels. Thus, 2WD mode is further divided into two, namely the front wheel which is called FWD while the rear wheel is called RWD.
- Front Wheel Drive (FWD)
FWD uses two front wheel drive mode. Usually, in the automotive industry, FWD is more profitable, because it doesn’t cost too much to use its components because it’s less than the others. In addition, because there are fewer components, cars with FWD tend to be lighter so they can save fuel.
The FWD engine is on the front side so that the engine load directly points to the two front wheel drives. This can increase the traction of the car, especially for slippery areas. Another advantage of FWD is that the price tends to be more affordable and the car becomes quite stable when on an incline due to the position of the engine and propulsion at the front.
- Rear Wheel Drive (RWD)
RWD is generally used by trucks and high-end sedans. Because, RWD can provide excellent traction to the truck when carrying heavy loads which makes traction on the two rear wheels increase. Meanwhile, luxury sedans use RWD to improve handling performance and balance the overall weight of the car. The drawback is, RWD has poor performance when on slippery or wet roads.
As the name implies, the 4WD drive mode distributes 4 wheels at once. Every corner of the wheel is provided with a power supply, so it really has good traction even when it is accelerating. The advantage is that 4WD cars are able to cross various terrains such as muddy, sandy roads, and others. Its use can be changed manually according to road conditions, so that drivers can change whether they want to use only two driving wheels or four wheels at once. In general, 4WD is widely used by off road cars considering that it is able to pass through a variety of quite extreme terrain.
All Wheel Drive (AWD)
AWD uses a limited slip differential and electronic clutch components . This also distinguishes AWD from 4WD which is the same thing, even though it is not. Because, AWD is designed with 100% control on each tire, while 4WD is designed with 50% control on the two front wheels and two rear wheels. Another plus, AWD mode can be used even on slippery roads. However, AWD also tends to be wasteful of fuel because the power is transmitted directly to the four wheels and puts a load on the engine.
