Four-wheel steering system functions, advantages, and disadvantages

August 9, 2017 | Car Technology

The newest steering technology to be implemented into vehicles is the four-wheel steering system. What is great about this technology is that it enhances the steering response and allows you to easily keep the vehicle stable while driving at higher speeds. And, of course, the rear wheels of the vehicle will turn left and right just like the front wheels. This is something you don’t see in two-wheel steering systems which only have the front wheels turn left and right. However, there are still some people that prefer two-wheel over four-wheel, and vice versa.

To figure out which is better, below are all the main advantages and disadvantages of a four-wheel steering system.

Advantages

  1. Better Steering Response – Your vehicle will respond faster to the steering that you perform overall. This allows your steering to be more precise and controllable on the road.
  2. Cornering Stability – When you’re going around a corner in a vehicle, four-wheel steering will give you control and stability as you drive. This especially comes in handy if the road is wet.
  3. Smaller Radius While Turning – Because you can turn the rear wheels in the opposite direction of the front wheels, this allows you to make smaller circular turns at lower speeds.
  4. Better on Tougher Terrains – If you live in an area with a lot of dirt roads or possibly snowy roads in the winter, then you’ll want a vehicle with four-wheel steering to help you drive better on these difficult terrains.
  5. Straight Line Stability – If you’re driving your vehicle down a straight road, the four-wheel steering will give you the best stability you could ever want. This helps when you have potholes and high winds within the environment.
  6. Easy Lane Changing – If you’re traveling fast on the interstate and you need to change lanes quickly, you can easily do so with a four-wheel steering vehicle without having to turn the steering wheel too much.

Disadvantages

  1. Expensive – As great as four-wheel steering systems are, they also require many more components in their construction than two-wheel steering systems. Because of this, vehicles with four-wheel steering are more expensive.
  2. Bigger Chance of Problems – Due to the fact that four-wheel steering systems have many components, especially electronic components, the entire system could become inoperable if just one of these components malfunctions. This means you’ll spend more time repairing or replacing components in a four-wheel steering system vehicle.
