Most of today's vehicles are bought with various features. Often, there will have to be made of a choice between an AWD and 4WD vehicle. Many buyers are often confused about the difference between an AWD and a 4WD vehicle, and that is understandable. Therefore, let's discuss the difference between the two to make an informed decision about the correct vehicles for you.
What is an All-Wheel Drive Vehicle?
The AWD designation means the powertrain powers both the rear and front wheels of the vehicle. A full-time option is also available where all four wheels are powered continuously. The part-time system primarily uses a two-wheel drive mode then can be switched to AWD when required for additional traction.
The automatic AWD designation powers all wheels automatically without driver intervention. However, more drive mode options are offered by some models for additional traction control. All systems drive the wheels providing torque through a system of couplings, differentials, and clutches.
What Designates a Four-Wheel Drive Vehicle?
More often than not, four-wheel drive is found in larger vehicles such as SUVs and trucks. A system of differentials along the front, center, and rear of the vehicle works with couplings and transfer cases to transfer power to all four wheels on demand.
As required, torque is delivered to all the wheels and is delivered either full-time or port-time similar to AWD. Also available is a selection mode between high and low ranges for driving, dependent on the terrain conditions. The desired mode is typically driver-selectable via a lever or switch. The low driving range is usually most appropriate for the most challenging driving conditions, while the high range is appropriate for less demanding surfaces such as snow, gravel, or sand.
