AWD vs. 4WD: What's The Difference?

One reason so many Darlington and Sumter drivers gravitate to BMW vehicles is because of their exceptional performance. Behind the incredible traction and handling of many BMW models, you’ll find the powerful xDrive intelligent all-wheel drive system. Found in most new BMW models, this all-wheel drive system allows engine power to automatically be sent to the wheels that need it most for an agile, curve-hugging ride. But what about four-wheel drive? What’s the difference between AWD and 4WD? Which is better: AWD or 4WD? Take a look with the team at BMW of Florence and see if AWD or 4WD best suits the way you drive.

Both AWD and 4WD are types of drivetrains that determine how the power from your engine is distributed to your tires on Marion streets. Most BMW models that don’t have AWD are equipped with rear-wheel drive, which means power is being sent to the rear wheels. While both AWD and 4WD direct power to all wheels, the way it does it separates the two. Take a look at the difference between AWD and 4WD below.

All-wheel drive systems like BMW’s xDrive direct torque from the engine to the front and rear axles through differentials. Intelligent AWD systems like xDrive detect which axle needs more power and automatically send the torque to the correct place. Other brands offer AWD systems that might require you to turn on AWD manually. Intelligent AWD like xDrive switch on automatically when the system senses rough or slippery terrain. AWD is most often found on unibody frames like you’ll find on BMW vehicles. This unibody frame is one of the reasons why you experience such a smooth and easy-to-handle drive in your BMW.

4WD is also known as four-wheel drive or 4×4. The primary difference between AWD and 4WD is that 4WD systems also send power to the front or rear axles as needed, but they can also direct amounts of power between the left and right wheels. This makes for an even more precise distribution of power needed in truly rugged driving scenarios, like off-roading. You’re most likely to find 4WD on vehicles where the body is built onto the frame, instead of it all being one piece like a unibody frame.

If you’re wondering which is better: AWD or 4WD? The answer depends on how you drive in Florence and beyond. AWD is plenty for most drivers who aren’t interested in off-roading, or drivers whose driving is mostly done in good conditions. 4WD is the way to go for more adventurous drivers who enjoy off-roading or are doing heavy work with their vehicles.
