I can honestly say that it’s pretty confusing. I personally have a Toyota 4Runner and when I bought it, they asked if I knew how to handle the 4WD (4 Wheel Drive). After like 1 minute of silence, I realized that they were talking to me so I just replied, “Well yeah, it has 4 wheels & I passed my driving test-so of course I know how to drive.” After that response, you can tell that they were going to have a hard time explaining it to me. So here’s what they told me:
4WD is a method that gives power to all four original wheels, whether it’s on a rough terrain for those adventures of yours, or just simply on the street.
AWD, or all-wheel drive, is essentially the same as 4WD, but they are less handy when it comes to off-roading. AWD is mainly for getting you from one place to another.
I’m still learning more about all of these options, but hopefully this sheds some light on your confusion.
Thanks for reading (:
