What does 4WD on a car mean?
1 Answers
4WD on a car stands for four-wheel drive, which distributes the engine's output torque to the wheels in varying proportions based on road conditions to achieve better handling and traction. Types of four-wheel drive systems: 1. Full-time 4WD: The vehicle is always driven by all four wheels independently; 2. Part-time 4WD: The driver manually switches between two-wheel drive and four-wheel drive modes via a transfer case based on road conditions; 3. On-demand 4WD: The system automatically switches between two-wheel drive and four-wheel drive depending on driving conditions, engaging four-wheel drive when necessary while remaining in two-wheel drive otherwise.
