Land Rover Discovery Sport, L550 (USA)

Additional Notes

• Two distinct rear differential fluid capacities appear across the 2.0 Si4 (177 kW) variants: 0.63 liter and 0.9 liter. Both values are listed under normal use conditions for the same engine and year ranges, indicating the presence of two different rear differential units fitted to the Land Rover Discovery Sport L550 depending on the specific build.
• The same dual-capacity pattern of 0.63 liter and 0.9 liter applies consistently across all three year ranges of the 2.0 Si4 (177 kW) engine: 2015-2016, 2016-2017, and 2017-2019. The overlap in model years between these ranges reflects mid-cycle specification updates rather than a single continuous revision.
• The 2.0 Si4 (213 kW) variant covering 2017-2019 carries the same two rear differential capacities of 0.63 liter and 0.9 liter seen in the lower-output 177 kW engine of the same period, suggesting shared drivetrain hardware across output levels in that generation.
• The P250 2.0 (183 kW) and P290 2.0 (213 kW) variants from 2019 onward both specify a single rear differential fluid capacity of 0.8 liter under normal use conditions. This contrasts with the earlier Si4 generations, which listed two separate capacity values, pointing to a standardized rear differential unit in the refreshed L550 lineup.
• A rear differential fluid capacity of 0.63 liter is a relatively small fill volume, consistent with compact integrated or open differential housings where the fluid reservoir is limited by the unit's physical size. The 0.9 liter figure suggests a larger or more complex unit, such as an active or torque-vectoring rear differential, which requires a greater fluid volume to lubricate additional clutch packs or mechanical components.
• The 0.8 liter capacity specified for the P250 and P290 models falls between the two earlier values of 0.63 and 0.9 liter, which is consistent with a revised rear differential design introduced with the 2019 model year refresh of the Discovery Sport L550.
