What does AWD mean?

[OJosephine]

AWD refers to the All-Wheel Drive system, which is commonly equipped on off-road vehicles and high-performance sedans. The All-Wheel Drive system is a driving mechanism where all four wheels independently propel the vehicle at all times. It distributes driving force to all four tires through a central differential and independent differentials on the front and rear axles. The functions of the All-Wheel Drive system are: 1. On hard surfaces or during rainy turns, the speed difference between the front and rear wheels is absorbed by the central differential, providing more reliable four-wheel traction; 2. On slippery surfaces such as ice, snow, or marshland, the central differential is locked, and it is unlocked when returning to normal road conditions.
