The drivetrain of a vehicle determines how power from the engine is transmitted to the wheels. While some vehicles send power to only two wheels (front-wheel drive or rear-wheel drive), others distribute power to all four wheels for enhanced traction and stability. A system providing power to all four wheels improves handling, particularly in challenging weather conditions like snow or rain, and offers better grip on various road surfaces.
Enhanced traction and stability systems have become increasingly desirable for drivers seeking safety and improved control. This demand has driven automakers to develop and refine such systems, contributing to a rise in their availability across various vehicle models. Historically, this capability was often limited to trucks and SUVs. The growing adoption in other vehicle segments reflects the increased value placed on enhanced performance and handling characteristics by drivers.
