Additional Notes
- Across all listed configurations of the BMW 6 Series Convertible F12, the automatic transmission fluid capacity is uniformly specified at 8.5 liters under normal use conditions.
- An 8.5-liter figure for automatic transmission fluid typically reflects a full service fill, meaning the quantity required when draining and refilling the transmission during a standard fluid service rather than a complete overhaul with torque converter replacement.
- The 640i Convertible covers the widest model year span in the specifications, running from 2011-2018, while the 650i Convertible and 650i xDrive Convertible are each listed only for 2011-2012.
- The 640i xDrive Convertible entered the lineup later than the rear-wheel-drive 640i Convertible, with specifications beginning from 2013 compared to 2011 for the non-xDrive variant.
- All four configurations share the same 8.5-liter capacity regardless of whether the drivetrain is rear-wheel drive or xDrive all-wheel drive, indicating the automatic transmission unit itself carries an identical fluid volume across both drivetrain layouts.
- All capacity figures are tied exclusively to normal use conditions, meaning the 8.5-liter specification applies to standard operating environments rather than severe-duty cycles such as towing, extreme temperatures, or high-performance driving.
