Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2012-2017 BMW 650i use?

The 2012-2017 BMW 650i is equipped with an all-wheel-drive (AWD) system known as xDrive. This system features a rear-biased torque distribution, typically sending 40% of power to the front wheels and 60% to the rear under normal conditions, with the ability to adjust torque dynamically based on driving conditions.

What is the transmission type and gear ratio for the 650i drivetrain?

The 2012-2017 BMW 650i comes with an 8-speed automatic transmission (ZF 8HP). The gear ratios are as follows: 1st (4.714), 2nd (3.143), 3rd (2.106), 4th (1.667), 5th (1.285), 6th (1.000), 7th (0.839), and 8th (0.667). The final drive ratio is 3.077.

What is the torque capacity of the 650i drivetrain?

The 2012-2017 BMW 650i drivetrain is designed to handle a maximum torque output of 450 lb-ft (610 Nm) from the 4.4-liter TwinPower Turbo V8 engine. The xDrive system and transmission are engineered to manage this torque efficiently across all driving conditions.

How often should the transfer case fluid be replaced in the 650i xDrive system?

BMW recommends replacing the transfer case fluid every 60,000 miles (96,000 km) or as specified in the vehicle's maintenance schedule. Use only BMW-approved transfer case fluid (part number 83 22 2 282 583) to ensure optimal performance and longevity.

What are the signs of drivetrain issues in the 650i?

Common signs of drivetrain issues include unusual noises (e.g., clunking or whining), vibrations during acceleration, difficulty shifting gears, or a warning light for the xDrive system. If any of these symptoms occur, it is recommended to have the vehicle inspected by a certified BMW technician immediately.
