When buying cars, all of the different engine types, makes, models, and built-in features can pretty much get confusing, especially when you’re not a car enthusiast. One thing you will probably hear come up a lot when searching for a new car is all-wheel drive (AWD) and four-wheel drive (4WD).
You may want to consider paying more attention because while it might seem like these two terms are interchangeable, they’re actually different.
Four-wheel drive is made for drivers who are a little more adventurous. Cars with 4WD are optimized for off-road driving such as going through mud, over boulders, and up steep hills with loose dirt.
This system is found mostly in big trucks and SUVs. Four-wheel drive works by sending torque to all four wheels to increase traction when needed. It’s available in both full-time and part-time, meaning, for instance, if the vehicle has part-time 4WD, the driver has the ability to switch it on and off. Additionally, some four-wheel-drive systems let the driver select how much power is given to each wheel.
All-wheel drive means that power is going to both the front and rear wheels of the vehicle all the time. Similar to four-wheel drive, AWD can be both part-time and full-time.
In vehicles with part-time AWD, the majority of the time the vehicle operates in two-wheel drive but when additional traction control is needed, all-wheel drive kicks in.
The main difference between part-time AWD and part-time 4WD is that the car will transition into AWD without the help of the driver. The system of such cars is designed to react when it senses a loss of traction. All-wheel drive is available in a much wider range of vehicles, from small sedans to large SUVs.
Does every driver need all-wheel drive or four-wheel drive?
The simple answer is no. The type of system your car needs will depend on where you live and if there is a need for you to use your vehicle in bad driving conditions. If you live in an area that gets a lot of snow or dirt, you might want to consider a vehicle with AWD or 4WD.
Four-wheel drive is better for people who live in rural areas and need to travel in deeper snow, mud or on roads that might not get plowed quickly. One thing you should however keep in mind is that while 4WD and AWD vehicles can help you get through a snowy or muddy road, they can’t help make the vehicle stop, so it’s always important to practice caution.
