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

If you’re someone who takes the St Paul detours, then you probably drive a vehicle with more than just front-wheel drive (FWD). Because of this, you’ve undoubtedly become familiar with the terms all-wheel drive (AWD) and four-wheel drive (4WD). What is the difference between AWD and 4WD? Learn some of the key differences between these two drivetrains with the service center at Motorwerks BMW as well as how BMW-specific AWD stands out among standard AWD. 

How Does 4WD Work?

Is AWD the same as 4WD? 4WD is a conventional 4×4 drivetrain, and one of the main differences between AWD and 4WD is that 4WD systems send power to the front and rear axles as well as direct a certain amount of power between the left and right wheels. Compared to AWD systems, 4×4 systems are built more for off-road capability, and Minneapolis drivers will usually find this kind of drivetrain in truck-based vehicles. 

How Does AWD Work?

AWD directs torque from the engine to the front and rear axles of all four wheels through differentials. In a nutshell, there are two different kinds of AWD systems: full-time AWD and part-time AWD. Full-time AWD sends torque to the front and rear axles all of the time, while part-time AWD systems only direct power to the front axle. Part-time AWD monitors road conditions and driving patterns to decide when it’s necessary to send power to the front axle. 

Usually, Richfield drivers will find AWD systems on vehicles with unibody frames, like a BMW 3 Series. 

Is AWD Better Than 4WD?

Which is better: AWD or 4WD? The type of system that is “better” for you will depend on what your driving needs are around Bloomington. Here are some distinguishers for which drivetrain system would be preferable based on different driving needs:

• AWD: Better for suburban-area drivers that need a little more traction control when weather conditions become unpredictable. 
• 4WD: Better for drivers who need optimal off-road stability and control on rough terrains. 

BMW xDrive AWD vs. Standard AWD

BMW vehicles are equipped with a specific system of AWD called xDrive AWD. How does xDrive compare to regular AWD systems? Standard AWD systems direct engine torque between the front and rear wheels. Here are some key characteristics of the BMW xDrive AWD: 

• Uses a multi-disc clutch integrated into the drivetrain that’s electronically controlled to monitor road conditions
• Constantly adapts to changing road conditions and decides how much power to direct to the front and rear axles based on the changing road conditions
