Land Rover Range Rover Sport, L461 (USA)

Additional Notes

• The P360 MHEV and P400 MHEV share an identical cooling system capacity range of 6.8–8.4 liters, reflecting the use of related inline-six mild hybrid engine architectures across both power outputs.
• A capacity range rather than a fixed value is listed for several configurations. In cooling system specifications, a range typically accounts for variation between a drain-and-refill service fill and a full system overhaul capacity, where the higher figure represents a completely drained system including all passages and the reservoir.
• The Land Rover Range Rover Sport P530 and P635, both equipped with the 4.4 V8 twin-turbo engine, share a cooling system capacity range of 8.7–10 liters. The larger range compared to the inline-six variants corresponds to the greater total coolant volume required by a V8 engine block and its associated cooling passages.
• The P440e plug-in hybrid lists two separate cooling system capacities: 7–9.1 liters for the combustion engine circuit and 2.1 liters for the battery cooling circuit. These are independent thermal management systems, each serving a distinct function within the powertrain.
• The P550e carries the same split cooling system structure as the P440e, with 7–9.1 liters for the combustion engine and 2.1 liters for the battery. The identical battery cooling capacity across both plug-in hybrid variants indicates a shared high-voltage battery thermal management system.
• The fixed 2.1-liter battery cooling capacity on both plug-in hybrid variants, in contrast to the range-format figures on the combustion engine circuits, suggests a sealed or low-variation circuit where total volume does not differ meaningfully between service and overhaul procedures.
• The P635 4.4 V8 twin-turbo, introduced from 2023, carries the same 8.7–10 liter cooling system capacity as the P530, indicating that the higher-output tune of the same engine does not alter the physical cooling system volume.
