AWD vs. 4WD – What’s The Difference?

Many of the vehicles on the market now come with many 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. Though the distinctions between the two can be bewildering, let’s go through each of these systems so you can make an informed decision about which car is best for you.

What exactly is AWD?

AWD indicates that the vehicle’s powertrain powers both the front and rear wheels. There is a full-time AWD option that continuously moves all four wheels. A part-time system operates primarily in two-wheel drive mode but will switch to AWD when traction is required.

The AWD feature works without the driver having to do anything to engage the system, though a few models on the market offer more control options. A set of differentials, couplings, and clutches will distribute torque to all four wheels.

What exactly is 4WD?

4WD is a feature seen primarily in larger vehicles such as SUVs and trucks. 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 will send torque to all of your vehicle’s wheels as needed, and it is available in full-time and part-time modes, just like AWD. When driving, you can also select from low and high ranges. Typically, this is accomplished via an electronic switch or a lever. The lowest setting provides the most traction, while the highest setting is useful for road surfaces that are only slightly slick, such as sand, snow, or gravel.
