AWD vs 4WD - What's the Difference?

Many of the vehicles on the market now come with several options. You may be able to pick between AWD and 4WD depending on the model you're looking at. Some individuals mistakenly believe that these are the same configurations; however, they are not. Distinctions between the two can be bewildering. Let's go through each of these systems to make an informed decision about which car is best for you.

What is All-Wheel Drive, and How Does It Work?

AWD means that the vehicle's powertrain drives both the front and rear wheels. There is a full-time AWD option that keeps all four wheels moving at all times. In most cases, a part-time system operates in two-wheel drive mode, but it will transition to AWD when traction is required.

The AWD technology works without the driver having to do anything. However, there are a few models on the market that allow extra control options. A series of differentials, couplings, and clutches will distribute torque to all four wheels.

What is 4WD?

Larger vehicles, such as SUVs and trucks, are more likely to have four-wheel drive. It transfers power to all four wheels using a set of differentials in the front, center, and rear and transfer cases and couplings.

The 4WD system distributes torque to all of your vehicle's wheels as needed, and it works in both full-time and part-time modes, much like AWD. When driving, you can pick between low and high ranges. This is often accomplished through the use of an electrical switch or a lever. A low setting provides the most grip, but a high setting is good for road surfaces that are only mildly slick, such as sand, snow, or gravel.
