How Does All-Wheel Drive Work?

All-Wheel Drive

As the snow begins to fall and drivers begin to rely on their all-wheel drive more than ever, they may ask themselves, “How does all-wheel drive work?” In a world where every new SUV seems to have all-wheel or four-wheel drive, it may seem confusing.

Fortunately, all-wheel drive is actually a simple system, allowing you to cruise over ice and snow with ease.

Vehicles that are equipped with all-wheel drive use a center differential, which splits the transmission power between the front and rear axles. When wheel sensors notice a loss of traction in one of the wheels – like if a wheel is slipping on ice – more transmission power will be sent to the wheels with more stability.

Most all-wheel drive vehicles are in all-wheel drive mode at all times, which is different than four-wheel drive – which usually only activates when necessary. When you are driving an all-wheel drive vehicle, you can be sure that your vehicle is constantly shifting power to the most reliable wheels.

Of course, some all-wheel drive systems are different than others. On-demand all-wheel drive keeps the focus on the front wheels until an issue is detected, whereas symmetrical all-wheel drive splits the focus four ways, at all times.
