Enhanced traction in challenging road conditions, such as snow, ice, or mud, represents a key capability of vehicles equipped with power distributed to all four wheels. For example, a vehicle navigating a steep, unpaved incline benefits from the improved grip provided by all wheels working in unison.
This capability offers increased stability and control, particularly in adverse weather or on uneven terrain, contributing to improved driver confidence and safety. While initially prominent in off-road vehicles and certain luxury models, this drivetrain technology has become increasingly common in a wider range of passenger vehicles, reflecting growing consumer demand for improved handling and all-weather performance.
