A drivetrain system that delivers power to all four wheels of a vehicle enhances traction on low-friction surfaces such as those encountered during winter weather. This capability allows for improved control and stability, particularly on snow or ice-covered roads, compared to two-wheel drive systems. For example, a vehicle equipped with this system can often navigate snowy inclines or unplowed roads more effectively.
Enhanced traction offered by such systems contributes significantly to automotive safety during challenging winter conditions. The ability to maintain control and avoid skids makes winter travel safer and reduces the risk of accidents. This technology has evolved over decades, with early implementations found in military and off-road vehicles before becoming a common feature in consumer vehicles. The increased prevalence of this feature reflects a growing emphasis on vehicle safety and performance in diverse conditions.
