Additional Notes
- The BMW 6 Series Gran Turismo G32 (USA) carries a split cooling architecture, with a high temperature cooling system holding 11.3 liters and a separate low temperature cooling system holding 4.1 liters across the 640i xDrive Gran Turismo configurations spanning 2017-2020.
- The high temperature circuit at 11.3 liters handles the primary engine thermal management, while the 4.1-liter low temperature circuit is a secondary loop typically associated with charge air cooling or ancillary component temperature regulation.
- The 640i xDrive Gran Turismo produced as of 01-08-2018 shares identical coolant capacities with the later 2019-2020 configuration, meaning the mid-cycle production date change did not alter the total system volume in either the high or low temperature circuits.
- The 2017-2019 row carries a production date qualifier of 01-08-2018, indicating the capacity figures apply specifically to vehicles built from that date onward within that model year span, rather than to the full 2017-2019 range without distinction.
