What type of 4WD system is AWD?

[Reagan]

AWD (All-Wheel Drive) is a full-time four-wheel drive system. Full-time four-wheel drive means that both the front and rear wheels of the vehicle have power, and the engine's output torque can be distributed in different proportions to all wheels based on the road conditions to improve the vehicle's driving capability. Four-wheel drive modes can be divided into full-time four-wheel drive and part-time four-wheel drive. The difference between them is that part-time four-wheel drive can switch between 4WD and 2WD, while full-time four-wheel drive is almost always in 4WD mode. Four-wheel drive systems are categorized as follows: 1. Full-time four-wheel drive: The vehicle is always driven by all four wheels independently; 2. Part-time four-wheel drive: The driver can manually engage or disengage the transfer case to switch between two-wheel drive and four-wheel drive based on road conditions; 3. On-demand four-wheel drive: The system automatically switches between 2WD and 4WD based on driving conditions, engaging four-wheel drive only when necessary and remaining in two-wheel drive otherwise.
