AWD vs 4WD - What's the Difference?
The average driver usually assumes that 4WD and AWD are the same. At first glance, this makes sense. After all, all-wheel drive means all four wheels. And 4WD seems to mean the same thing. In reality, there are a few key differences to these systems that make it important for a driver to choose the proper one for their goals. Let's see how they differ compared against one another in various situations.
What is All-Wheel Drive?
An all-wheel drive system tends to run automatically through computer systems and is functioning at all times for a driver (Full-time AWD). In other instances, AWD will function with two wheels in decent road conditions and 4-wheels when the roads become slippery or challenging (part-time AWD). Models that have limited towing capacity or don't need highly configurable drive settings - such as family SUVs or sedans - are usually the recipients of a good all-wheel drive setup. Because AWD tends to run seamlessly and with no input, novice drivers can feel perfectly at home using AWD. Many of today's most popular sedans and family SUVs use an AWD system, sometimes lengthened out to All-Wheel Drive. If you want a system where there's not a lot of fuss, part or full-time AWD is going to be a great bet for you.
What is Four-Wheel Drive?
The average off-road SUV or truck is going to have a more complex system called 4WD. This system operates with transfer cases and couplings, delivering a more driver-focused setup that meets unique demands during interactions with challenging terrain or major towing operations. A driver can use a low setting for maximum traction or a high setting for regular weather challenges (snow or rain for example). The primary difference between 4WD and AWD is that the 4WD configuration might need interaction from the driver in order to reach its maximum usefulness. In AWD situations, you'll find that a computer and sensors determine road conditions and then automatically set up AWD. For 4WD, this is more for those who need to really customize where torque goes to each of the wheels.
