Additional Notes

  • The Mazda CX-90 (USA / CAN) front differential holds 0.35 liter across all three AWD configurations covered in the specifications, namely the e-PHEV AWD, e-SkyActiv AWD, and e-SkyActiv High Output AWD.
  • A 0.35-liter front differential capacity is a notably small fill volume, consistent with compact front differential housings found in AWD systems where the front axle operates as a secondary drive unit rather than a primary one.
  • The rear differential capacity is listed at 0.9 liter for all three AWD variants, representing a volume more than twice that of the front unit, which reflects the rear differential's larger housing and its role as the primary torque-distributing component in rear-biased AWD layouts.
  • All six capacity entries in the specifications are designated for normal use conditions, meaning none of the listed fill volumes are associated with a severe-use or first-change interval distinction.
  • The front differential capacity of 0.35 liter is identical across the e-PHEV AWD, e-SkyActiv AWD, and e-SkyActiv High Output AWD configurations, indicating a shared front differential assembly regardless of powertrain type.
  • The rear differential capacity of 0.9 liter likewise shows no variation between the plug-in hybrid e-PHEV AWD and the mild-hybrid e-SkyActiv variants, suggesting a common rear differential unit is used across the powertrain lineup starting from 2023.
