Additional Notes

  • All three 2023 Mazda CX-90 (USA / CAN) configurations — the e-PHEV AWD, e-SkyActiv AWD, and e-SkyActiv High Output AWD — share an identical automatic transmission fluid capacity of 7.3 liters.
  • A 7.3-liter capacity is consistent with a full transmission service fill, meaning the figure accounts for the fluid volume held within the transmission assembly during normal operating service.
  • The e-PHEV AWD variant pairs a plug-in hybrid electric system with an automatic transmission, and despite the added complexity of the hybrid drivetrain, the automatic transmission fluid capacity remains at 7.3 liters, the same as the non-hybrid inline-six configurations.
  • The e-SkyActiv and e-SkyActiv High Output AWD configurations represent two distinct inline-six mild-hybrid outputs, yet both carry the same 7.3-liter automatic transmission fluid specification, indicating a shared transmission unit across those two power levels.
  • All three configurations carry a normal use condition designation for the 7.3-liter automatic transmission fluid capacity, meaning the specification applies to standard driving conditions rather than a severe or first-change-only service scenario.
