AWDS, or All-Wheel Drive System, is a term mostly used in the automotive industry to describe a vehicle's ability to distribute power to all four wheels for improved performance, traction, and stability. However, there are various other synonyms for this term, including 4x4, four-wheel drive, and quad-drive. 4x4 refers to a vehicle with a two-speed transfer case that provides power to all four wheels, while four-wheel drive is a broad term for any vehicle with power distributed to all four wheels. Quad-drive, on the other hand, is a Chrysler term that describes a four-wheel drive system with electronic limited-slip differentials for optimized traction and handling on any surface.
