Has the BMW X3 been changed to an on-demand all-wheel drive system?

BMW X3 has been changed to an on-demand all-wheel drive system. The on-demand all-wheel drive system is a drivetrain that only switches to four-wheel drive when appropriate, while remaining in two-wheel drive under other circumstances. The on-demand all-wheel drive system automatically switches between two-wheel drive and four-wheel drive modes based on the vehicle's driving conditions, without requiring manual operation. The BMW X3 is an SUV model under the BMW brand, featuring two exterior designs: the Luxury Design Package and the M Sport Package, with a black and beige dual-tone interior. The BMW X3 is equipped with a 2.0T turbocharged engine, offering three power outputs depending on the model: 184 horsepower (xDrive25i), 224 horsepower (xDrive28i), and 252 horsepower (xDrive30i). The transmission system is paired with an 8-speed automatic transmission.
The BMW X3 has consistently employed the xDrive system, BMW's signature all-wheel-drive technology. Unlike conventional full-time systems that constantly deliver power, xDrive intelligently prioritizes rear-wheel drive during normal driving to conserve fuel, automatically distributing torque to the front wheels only when wheel slip or unstable road conditions are detected—functioning similarly to an on-demand AWD system. This design relies on sensors that continuously monitor traction and steering inputs, enabling rapid responses on wet or snowy surfaces to enhance safety and driving enjoyment. For instance, it instantly engages when cornering on gravel roads in suburban areas, improving body stability. Since the 2023 model year, a software update has made the system react even faster while improving energy efficiency. Overall, BMW has retained xDrive rather than reverting to a pure on-demand AWD system because it strikes a balance between performance and efficiency, avoiding the abruptness of simpler switching systems.
As an owner of a BMW X3 with over 30,000 kilometers driven, I've experienced how the xDrive system automatically adjusts the power distribution between the front and rear wheels. For instance, during high-speed cornering on rainy days, it instantly engages all-wheel drive to stabilize the vehicle, while remaining fuel-efficient in urban driving—almost like an on-demand AWD system. BMW hasn't altered the fundamental architecture, but each generation sees more refined tuning. The latest iX3 electric version's AWD follows similar logic. I find this intelligent system more reliable than conventional on-demand AWD, especially on muddy mountain roads. As an owner, I recommend regular tire checks and software updates to ensure optimal performance. Fellow owners generally agree that BMW maintains this design for all-weather safety considerations.
