Are 4WD Vehicles More Stable in Rainy Weather?
1 Answers
4WD vehicles are more stable on slippery roads. Four-wheel drive refers to a vehicle maintaining a four-wheel drive form throughout the entire driving process. The following are specific introductions to the 4WD system modes: 1. Full-time drive: The front and rear wheels always maintain a 4-wheel drive mode, with the engine output torque set at a 50:50 ratio between the front and rear wheels during driving. Full-time drive offers excellent driving control and tracking performance, but it consumes more fuel and has poor fuel economy. 2. Part-time drive: The driver can switch between 2-wheel drive or 4-wheel drive modes by engaging or disengaging the transfer case based on road conditions. This is the most common drive mode for general off-road vehicles or 4WD SUVs. 3. On-demand drive: The drive mode is controlled by the computer. Normally, (front) rear-wheel drive is used on regular road surfaces. If the road conditions are poor or the drive wheels slip, the computer will automatically detect and immediately distribute the engine output torque to the other two wheels, switching to 4-wheel drive mode. This mode is simple to operate.
