Additional Notes
- The BMW 7 Series G11/G12 transfer case fluid capacity is specified at 0.7 liter across all listed xDrive configurations, a figure consistent with the compact, single-speed transfer cases commonly found in longitudinal all-wheel-drive platforms of this class.
- A 0.7-liter capacity reflects a service fill volume, meaning the amount of fluid required when servicing the unit without full disassembly, rather than a complete overhaul fill that would account for residual fluid in passages and components.
- The 740i xDrive spans two specification entries covering 2016-2019 and 2019-2022, both returning the same 0.7-liter transfer case capacity, indicating no change in transfer case fluid volume between those generation intervals.
- The 750i xDrive similarly carries entries for 2015-2019 and 2019-2022, with the 0.7-liter capacity held constant across both periods, placing the V8-powered variant on the same transfer case fluid specification as the inline-six 740i xDrive.
- All four rows are designated under normal use conditions, meaning the stated 0.7-liter capacity applies to standard operating environments rather than severe-duty cycles such as frequent towing, off-road use, or extreme temperature exposure.
- The 750i xDrive coverage begins in 2015, one year earlier than the 740i xDrive entries, which start in 2016, reflecting the staggered model introduction of the G11/G12 generation in the US market.
