[Updated 2020] AWD vs. RWD: Where Is Your Choice?


It is typical for drivers having a concentration on a track-like dynamics to compare AWD vs. RWD, particularly with sporty versions such as the Kia Stinger currently providing RWD performance.

There is no Ideal answer because they deliver distinct benefits, but Colorfy is here to talk you through:

  • The difference between AWD v.s RWD
  • The benefit of an All-Wheel Drive (AWD) automobile in contrast to Rear-Wheel Drive (RWD)

What is the Difference Between AWD & RWD?

What is the Difference Between AWD & RWD

Before getting to the particulars of AWD vs. RWD, it helps to lay out exactly how each system operates:

RWD (Rear-Wheel Drive)

As you may have figured, RWD vehicles station electricity simply to the trunk. This was the most typical drive system before FWD was released in the early’80s, but the installation is still utilized to deliver greater horsepower and manage increased vehicle weights.

AWD (All-Wheel Drive)

Often mistaken with 4WD, AWD may also participate in all four wheels but does not do this all of the time. During regular driving, AWD vehicles generally are the FWD vehicles. When a wheel loses grip, AWD kicks in to keep the car in check.

The two AWD and RWD installations deliver exceptional performance in comparison to FWD vehicles, but which one you choose will depend on your priorities.

AWD for Safety

As AWD vehicles may lead power to all four wheels, they are a superb option if you expect to pay snowy, icy, slick, or muddy surfaces. You will be less likely to eliminate control and more inclined to work your way free if you get stuck.

RWD for Performance

Since AWD vehicles need heavier and lighter parts, they consume more fuel than RWD versions, which are inclined to be much milder.

AWD for Choice

The Kia Stinger is a superb option, but it is among those few RWD models out there. By comparison, you will discover lots of all Kia models available with AWD, such as the Sportage and Sorento.

RWD for Durability

RWD systems are simple and rugged, so it’s possible to set them through lots of misuses without necessarily anticipating costly repair bills.

The benefit of an All-Wheel Drive (AWD) automobile in contrast to Rear-Wheel Drive (RWD)

The accepted understanding of an All-Wheel Drive automobile is the fact that it pushes each the brakes all the time. In other words, whatever the sort of street surface or the program where the AWD car is used, all four wheels are used to create forward momentum. A Rear-Wheel Drive automobile as its name describes just uses two of those four wheels to create forward momentum.

This usually means that AWD vehicles have double the grip accessible to transmit driving forces compared to this, which will be open to an RWD car of the identical weight and semi-automatic configuration.

This characteristic of AWD vehicles using double the traction is a substantial safety advantage since the stability and level of driver management of their very best AWD is higher than that of their very best Rear-Wheel Drive car once the car has been pushed forward.

1 instance of the greater level of security in AWD vehicles is through a shoot-off in a street intersection on a slick road, where the degree of traction between Tyre and street is reduced and the driver is hoping to maneuver to a gap in the oncoming traffic.

The benefit of an All-Wheel Drive (AWD) automobile in contrast to Rear-Wheel Drive (RWD)

Based upon the coefficient of friction between the tyre and road surface every tyre has the highest degree of traction. In the event, the sum of engine power placed on the wheel surpasses the available grip the tyre will eliminate grip and the wheel will spin. In the instance of an All-Wheel Drive automobile, because the entire motor drive is spread to all four wheels, each tyre is just required to transmit 1 quarter of their total and so it is less probable that the tyre will eliminate traction and spin. This implies that since an AWD car is driving all four wheels that the whole drive force is not as likely to exceed the sum of grip necessary to maneuver the vehicle ahead.

The outcome is much more secure and trustworthy acceleration of the automobile to the gap in the oncoming traffic, because in this scenario the traction of the ideal AWD car is double that of the very best RWD car.

Another important case of the greater degree of security of an All-Wheel Drive automobile, when compared with your Rear-Wheel Drive automobile, is when cornering under driveway electricity. The tyres in an AWD car are hauling half of the entire drive force when compared with some Rear-Wheel Drive automobiles. When cornering not merely is a tyre transmitting driving forces but also cornering forces. Since a Rear-Wheel Drive automobile drive axle is hauling twice the driving forces of an All-Wheel Drive automobile there is not as much grip accessible for cornering forces.

This implies in an RWD car if engine power raises and utilizes much more of the available traction exiting inadequate traction for cornering forces the tyre will eliminate grip and slide sideways. This ends in the back of the car sliding sideways in what’s called oversteer manoeuvre, meaning that the automobile turns a bigger radius of a turn compared to the driver planned.

As an All-Wheel Drive automobile only transmits half the drive pressure at each wheel, the total amount of traction available for cornering drives is higher than a Rear-Wheel Drive automobile for exactly the identical degree of motor power. Meaning that the ideal AWD automobile will shed sideways traction at higher cornering forces compared to the very best RWD car.

The outcome is the All-Wheel Drive automobile that may more safely negotiate a corner beneath drive electricity that suddenly and unexpectedly is much more slippery than the motorist anticipated.
