Additional Notes

  • The Hyundai Bayon BC3 manual transaxle fluid capacity varies by engine. The 1.0 T-GDI variants, including both 48V-Hybrid outputs, hold 1.5-1.6 liters, while the 1.2 MPi transaxle holds a noticeably smaller 1.3-1.4 liters.
  • A capacity expressed as a range rather than a fixed value typically reflects manufacturing tolerances and the practical limits of a drain-and-refill service, where full recovery of the previous fluid charge is not always achievable.
  • Across all engine variants, the manual transaxle fluid interval under normal use conditions is a check at 48 months or 60,000 km, whichever comes first, with no fluid change specified for that condition.
  • Under severe use conditions, all variants share a check interval of 60,000 km or 48 months, combined with a mandatory fluid change at 120,000 km. The check interval distance matches the normal condition, though the addition of a change interval distinguishes severe service requirements.
  • The 1.2 MPi covers model years 2020-2023, and its transaxle capacity of 1.3-1.4 liters is lower than the 1.0 T-GDI figure. A smaller transaxle unit paired with a naturally aspirated engine commonly corresponds to a reduced fluid volume compared to turbocharged applications.
  • Both 48V-Hybrid configurations of the 1.0 T-GDI, rated at 74 kW and 88 kW respectively, share identical manual transaxle fluid capacities and service intervals, indicating no differentiation in transaxle specification between the two power outputs.
  • The 88 kW 48V-Hybrid variant is listed for 2020-2024, while the 74 kW 48V-Hybrid carries a starting year of 2020 without a closing year in the specifications.
