The tendency of rear-wheel-drive (RWD) vehicles to skid mainly stems from their mechanical structure and power distribution characteristics. Since core components like the engine are concentrated in the front compartment, the weight distribution between the front and rear wheels is uneven (typically 55% on the front wheels and 45% on the rear wheels). As the driving wheels, the rear wheels have weaker grip due to insufficient load-bearing, especially on wet or icy roads where the friction coefficient drops sharply, making the rear wheels more likely to exceed the grip limit. For power transmission, RWD vehicles "push" the body via the rear wheels. When starting or accelerating rapidly, they need to overcome greater static friction. If the torque output exceeds the road adhesion (for example, a 2.0T engine may output 400N·m of torque on ice, but the rear wheel grip threshold is only about 300N·m), it will cause wheelspin. Data shows that the loss-of-control rate of RWD vehicles in snow-covered corners is 30% higher than that of front-wheel-drive vehicles. About 68% of RWD vehicle accidents on ice and snow are related to operational errors. To reduce risks, It is best to switch to snow tyres (which can increase grip by 40%), activate snow mode to limit torque, avoid rapid acceleration and sharp steering, and maintain a longer following distance. These measures can improve the stability of RWD vehicles on low-adhesion roads while preserving their unique handling characteristics.
