Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2015-Present BMW 750i use?

The 2015-Present BMW 750i features an xDrive all-wheel-drive (AWD) system. This system is paired with an 8-speed Steptronic automatic transmission and a 4.4-liter TwinPower Turbo V8 engine, delivering 523 horsepower and 553 lb-ft of torque.

What is the torque rating of the drivetrain in the BMW 750i?

The drivetrain in the BMW 750i is rated for a maximum torque of 553 lb-ft (750 Nm) at 1,800-4,500 rpm. This ensures optimal performance and acceleration across a wide range of driving conditions.

How does the xDrive system improve drivetrain performance?

The xDrive system dynamically distributes torque between the front and rear axles, with a default 40:60 front-to-rear split. It continuously adjusts based on driving conditions, improving traction, stability, and handling, especially in adverse weather or uneven terrain.

What is the recommended service interval for the drivetrain components?

BMW recommends inspecting the drivetrain components, including the transfer case, differential, and driveshaft, every 30,000 miles or 3 years, whichever comes first. Fluid changes for the transfer case and differential should be performed every 60,000 miles or as specified in the owner's manual.

Can the drivetrain handle high-performance modifications?

While the drivetrain is robust, modifications such as increased horsepower or torque beyond factory specifications may require upgraded components, including the transmission, driveshaft, and differential. Unauthorized modifications can void the warranty and compromise safety.
