Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2012-2018 BMW M6 use?

The 2012-2018 BMW M6 features a rear-wheel-drive (RWD) system with an optional M xDrive all-wheel-drive (AWD) system for enhanced traction and performance. The drivetrain is paired with a 7-speed M Double Clutch Transmission (M DCT) or a 6-speed manual transmission.

What is the torque capacity of the M6's drivetrain?

The drivetrain in the BMW M6 is designed to handle up to 680 Nm (502 lb-ft) of torque, which is the maximum torque output of the 4.4-liter S63 twin-turbocharged V8 engine.

How does the Active M Differential work in the M6?

The Active M Differential is an electronically controlled limited-slip differential that optimizes traction and stability. It uses wheel speed sensors and driving dynamics data to distribute torque between the rear wheels, improving cornering performance and reducing wheel spin.

What is the recommended service interval for the drivetrain components?

BMW recommends inspecting the drivetrain components, including the transmission, differential, and driveshaft, every 30,000 miles or 2 years, whichever comes first. Fluid changes for the transmission and differential should be performed every 60,000 miles or 4 years.

Can the M6's drivetrain handle high-performance modifications?

While the M6's drivetrain is robust, significant modifications such as increased engine power or torque may require upgrades to the transmission, differential, or driveshaft to ensure reliability. Always consult a BMW-certified technician before making performance modifications.
