Mercedes-Benz AMG GT 4-Doors, X290 (EU)

Additional Notes

• Across all five configurations of the Mercedes-Benz AMG GT 4-Door X290, the transfer case fluid capacity falls within a range of 0.65 to 0.68 liter. A specified range rather than a single fixed value reflects normal manufacturing tolerances in the transfer case housing, meaning the exact fill amount is confirmed by level rather than by volume alone.
• The AMG GT 43 4MATIC+ (290.659) and AMG GT 53 4MATIC+ (290.661) share an identical transfer case fluid change interval of 125,000 km under normal use conditions, which is notably longer than the interval assigned to the higher-output variants.
• The AMG GT 63 4MATIC+ (290.688) and AMG GT 63 S 4MATIC+ (290.689) carry a transfer case fluid change interval of 75,000 km or 36 months under normal use, whichever comes first. The addition of a time-based limit alongside the distance figure means the interval is governed by both mileage accumulation and calendar time.
• The 75,000 km or 36-month interval on the AMG GT 63 variants represents a significantly shorter service cycle compared to the 125,000 km interval on the AMG GT 43 and AMG GT 53, a difference of 50,000 km between the two groups despite an identical fluid capacity range across all rows.
• The AMG GT 63 S E Performance 4MATIC+ (290.679), introduced from 2022, follows the same 75,000 km or 36-month change interval and 0.65-0.68 liter capacity as the standard AMG GT 63 and AMG GT 63 S, placing all three V8-based and hybrid-performance variants within the same service specification.
• All five configurations are designated under normal use conditions, meaning the stated intervals and capacities apply to standard operating environments rather than a more demanding severe-use classification.
