Additional Notes

  • Both diesel configurations of the Maserati Quattroporte M156 share an identical AdBlue tank capacity of 19.6 liters, which is a relatively large reservoir typical of vehicles designed to extend refill intervals between scheduled maintenance visits.
  • The 19.6-liter capacity applies equally to the 184 kW and 202 kW diesel variants, meaning neither engine output level requires a differently sized AdBlue system despite the difference in power rating.
  • The check interval for AdBlue is set at 20,000 km or 12 months under normal use conditions, whichever comes first, applying to both diesel variants across the 2018-2021 model years.
  • Both diesel variants are equipped with a selective catalytic reduction system, which is the emissions control technology that consumes AdBlue to reduce nitrogen oxide output in the exhaust stream.
  • The 184 kW variant is specifically noted as the Italy-market configuration, distinguishing a regional specification within the same model year range of 2018-2021.
