What does the 'xDrive' feature in BMW X3 do?

I've noticed that the BMW X3 has a feature called 'xDrive', but I'm not sure what it does. Can you explain its purpose and how it benefits the driving experience?

xDrive is BMW's all-wheel drive system that helps with traction and stability on different road conditions. It constantly monitors the vehicle's steering, acceleration, and braking to distribute power between the front and rear axles as needed. This allows for better control and handling, especially in adverse weather conditions.
