Additional Notes

  • The INFINITI Q50 HV37 (EU) automatic transmission holds 7 liters of fluid across all listed configurations, a figure that represents a service fill capacity rather than a full overhaul fill, which would typically account for fluid retained in the torque converter and valve body.
  • The 7-liter capacity applies uniformly to both the rear-wheel-drive 3.5 Hybrid and the AWD variant, indicating no measurable difference in transmission fluid volume between the two drivetrain layouts for the HV37 platform.
  • All listed configurations carry a check interval of 15,000 km or 12 months, whichever comes first, under normal use conditions, meaning the interval is tied to a dual trigger rather than a single mileage or time threshold alone.
  • The 3.5 Hybrid AWD configuration spans three separate model year groupings in the specifications: 2013-2015, 2015-2017, and 2018-2020, each carrying identical capacity and interval values of 7 liters and 15,000 km/12 months.
  • The 3.5 Hybrid rear-wheel-drive configuration is grouped into two ranges, 2013-2017 and 2018-2020, both sharing the same 7-liter capacity and 15,000 km/12-month check interval under normal use.
  • A 15,000 km or 12-month check interval for automatic transmission fluid is a relatively frequent schedule, reflecting the added thermal and mechanical demands associated with hybrid powertrains, where the transmission interacts with both an internal combustion engine and an electric motor.
