Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2019-2021 BMW X6 use?

The 2019-2021 BMW X6 is equipped with an intelligent all-wheel-drive system called xDrive. This system dynamically distributes power between the front and rear axles, with a default 40:60 front-to-rear torque split, ensuring optimal traction and stability in various driving conditions.

What is the maximum torque capacity of the drivetrain in the BMW X6?

The drivetrain in the BMW X6 is designed to handle up to 750 Nm (553 lb-ft) of torque, depending on the engine variant. For example, the X6 M50i with the 4.4L V8 engine produces 650 Nm (479 lb-ft) of torque, while the X6 M Competition generates 750 Nm (553 lb-ft).

Can the xDrive system be manually adjusted or disabled?

No, the xDrive system is fully automatic and cannot be manually disabled. However, drivers can select different driving modes (e.g., Comfort, Sport, Eco Pro) that adjust the system's behavior to prioritize efficiency, performance, or stability.

What is the maintenance interval for the drivetrain components?

BMW recommends inspecting the drivetrain components, including the transfer case and driveshaft, every 30,000 miles or 24 months, whichever comes first. Regular fluid changes for the transfer case and differentials are also required, typically every 60,000 miles.

What type of differential is used in the BMW X6?

The BMW X6 uses an electronically controlled multi-plate clutch differential as part of the xDrive system. This allows for precise torque distribution between the front and rear axles, enhancing traction and handling performance.
