Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2016-2021 BMW M2 use?

The 2016-2021 BMW M2 features a rear-wheel-drive (RWD) drivetrain with an optional M DCT (Dual Clutch Transmission) or a standard 6-speed manual transmission. The system includes a limited-slip differential (LSD) for improved traction and handling.

What is the torque capacity of the drivetrain in the BMW M2?

The drivetrain in the BMW M2 is designed to handle up to 500 Nm (369 lb-ft) of torque, which is the maximum torque output of the N55 (2016-2018) and S55 (2019-2021) engines used in this model.

How does the limited-slip differential (LSD) work in the BMW M2?

The limited-slip differential in the BMW M2 uses a mechanical locking mechanism to distribute torque between the rear wheels. It provides up to 60% lock under acceleration and 40% lock during deceleration, enhancing stability and cornering performance.

What is the recommended service interval for the drivetrain components?

BMW recommends inspecting the drivetrain components, including the differential and driveshaft, every 30,000 miles or 3 years, whichever comes first. Transmission fluid should be replaced every 60,000 miles for the M DCT and every 50,000 miles for the manual transmission.

Can the drivetrain handle aftermarket performance upgrades?

The drivetrain in the BMW M2 is robust and can handle moderate performance upgrades. However, significant increases in power (e.g., turbocharger upgrades) may require reinforcing the drivetrain components, such as the driveshaft or differential, to prevent failure.
