AWD definition and meaning
All-wheel drive (AWD) is a vehicle drivetrain that allows all four wheels to simultaneously receive power from the engine. This can provide increased traction and stability, especially in slippery or off-road conditions.
While AWD systems have been around for decades, they have become increasingly popular in recent years as more and more automakers offer them as an option on their vehicles. Not all AWD systems are created equal; some are better suited for certain types of driving than others.
There are two basic types of AWD systems: full-time and part-time.
Full-time AWD systems are always operating, sending power to all four wheels even when it’s not necessarily needed. This can put a strain on the engine and drivetrain components. However, many manufacturers designed their systems to be “smart” and only engage the rear wheels when necessary.
On the other hand, part-time systems are typically found in off-road vehicles. They’re designed to be engaged only when needed, such as when driving in low-traction conditions. This helps to conserve energy and prevent unnecessary wear and tear on the system.
There are also a few ways that power can be distributed to the wheels in an AWD system.
One common method is known as “torque vectoring.” This uses sensors to monitor the speed and rotational force of each wheel and then sends power to the individual wheel that needs it the most. This can help improve traction and stability, especially when cornering.
Another common method is known as “center differential locking.” This locks the center differential, which connects the front and rear axles, whenever extra traction is needed. This distributes power evenly to all four wheels and can help prevent loss of control, even in extreme off-road conditions.
AWD systems can provide increased traction and stability, especially in slippery or off-road conditions. However, they can also put a strain on the engine and drivetrain components and may not be necessary for all types of driving. When considering a vehicle with AWD, it’s important to understand how the system works and what its benefits and drawbacks are.
