AWD (All-Wheel Drive):
General Explanation: All-Wheel Drive (AWD) is a system in a vehicle that drives all four wheels at all times. This means that power from the engine is distributed to all four wheels, providing better traction and control in various driving conditions. AWD systems use differentials to split the engine's power to the wheels based on which ones have the most traction. This helps improve stability and handling, especially in slippery or uneven road conditions.
