All-wheel drive (AWD) and four-wheel drive (4WD) — They’re the same thing, right? I mean, all cars have four wheels...Well, actually, the two systems are quite different.
Even with all the online resources, car shopping can still be a real pain. There’s a long list of confusing topics to go through and AWD and 4WD often seems to confuse some people.
The key intention of both systems is to help with a car’s traction, assisting its acceleration in bad conditions. However, they do have their differences. Let’s dive in and take a look at AWD and 4WD.
AWD
As the name implies, AWD sends power to all corners, all the time. Unlike 4WD, you can never turn it off. AWD systems are engineered to enhance on-road performance for all-weather traction.
AWD propels power to the wheels with the most traction by dividing power between the front and rear axles on the center differential and the individual wheels by way of the front and rear differential.
AWD can transition from pavement to slippery conditions, such as snow, rain, or dirt virtually instantaneously.
4WD
4WD functions by locking the front and rear axles together, splitting torque between them. This provides great traction, but a vehicle locked in 4WD cannot safely be operated on dry pavement because its front and rear axles are forced to rotate at the same speeds. However, 4WD is the best option for off-road capability.
Unlike AWD, it can be turn on and off to improve fuel economy. The downside is that 4WD is usually a much more expensive option than AWD.
Whether you need a 4WD vehicle for off-roading or an AWD vehicle for all-year round, you're getting a reliable vehicle. Be sure to consult your dealer to determine which option is best for you and your needs.
