Is BMW xDrive a full-time four-wheel drive system?

BMW xDrive is not a full-time four-wheel drive system; it is an on-demand four-wheel drive system. The xDrive system can be found in many BMW sedans and SUV models. There are three types of four-wheel drive systems: full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive. The on-demand four-wheel drive system automatically switches between four-wheel drive and two-wheel drive via computer control, requiring no input from the driver. BMW xDrive intelligent all-wheel drive system sets new standards in the responsiveness of all-wheel drive. BMW (abbreviated from Bavarian Motor Works) is a German automotive brand under the BMW Group. It has four model series: I, X, Z, and pure numeric models (1, 2, 3, etc.), along with the M series (BMW's official high-performance division) based on improvements to these series. The BMW logo stands for Bavarian Motor Works, and the colors and design of the logo are derived from the coat of arms of Bavaria, where BMW is headquartered.
From my years of driving experience, BMW xDrive is indeed a full-time all-wheel-drive system, meaning it constantly distributes power to all four wheels, unlike some brands that only activate AWD when slippage occurs. I've driven many BMW models, such as the X series, and in rainy or snowy conditions, xDrive automatically adjusts power distribution between the front and rear axles, keeping the car rock steady. This system incorporates electronic control and a transfer case to monitor tire grip in real-time, ensuring safer driving. I recall it significantly reduces skidding risks during turns, which is particularly helpful for novice drivers. Of course, full-time AWD does increase fuel consumption slightly, averaging about 10-15% more, but it's worth it for the added safety. BMW has been developing xDrive for 20 years, and it's become increasingly intelligent – I've never had any issues driving on slippery roads.
