Maserati Quattroporte, M156

Additional Notes

• The Maserati Quattroporte M156 in S Q4 configuration carries a transfer case fluid capacity of 0.62 liter across all listed model year ranges, from 2013 through the Modena variant introduced in 2021.
• A capacity of 0.62 liter is a relatively small volume, consistent with a compact transfer box unit rather than a larger, gear-driven transfer case assembly found in body-on-frame four-wheel-drive vehicles.
• All five configurations share the same 0.62 liter figure under normal use conditions, meaning the specified capacity applies to standard operating environments rather than severe-duty or off-road service cycles.
• The S Q4 designation identifies the all-wheel-drive variant of the Quattroporte M156, which is the only configuration in the provided specifications to carry a transfer case fluid entry, as the Q4 suffix denotes the presence of the transfer box component itself.
• The 2013-2016 and 2016-2017 entries represent two distinct specification rows for overlapping or transitional production periods, yet both carry the identical 0.62 liter capacity, indicating no change in transfer box fluid volume across that boundary.
• The Quattroporte S Q4 Modena, listed from 2021, retains the same 0.62 liter transfer box capacity as earlier S Q4 variants, showing continuity in the transfer case specification despite the Modena trim designation representing a later production revision.
