1. Engine

The Maserati Quattroporte isfittedwithtwo differentengines(F136S and F136UC). Both enginesare all-alloy90°8 cylinderV-engineswith a total displacementof 4.2 litres. The maindifferencebetweenbothenginesliesin the lubricationsystem. Power and torque figuresof bothenginesare comparable.

The F136S dry sumpengineisusedin the Quattroporte modelswithDuoselect transmission. Thisengineisanevolutionof the F136R engineasusedin the M138 models. Certainmodificationsweremadeto the cylinderheads, intakemanifoldand enginesoftware.

The F136UC wetsumpengineisusedforthe Quattroporte modelswithZF automatic transmission. Althoughthisengineisconsideredasanevolutionof the F136R/S engine, 80% of itscomponentsare new.

Bothenginescan easilybeidentifiedwhenopening the bonnetasthe dry sumpengine hasredcylinderhead covers, whileforthe wetsumpenginetheyare paintedin blue.

Forthe introductionof the Quattroporte withautomatictransmission, a new enginewitha traditional, wetsumplubricationsystem was developped. Thissolutionisconsideredas more adequateforthe applicationin Maserati vehiclesasitislessnoisyasa dry sump enginewithitsexternal, multiple oil pump. Thisenginehasmaintainedthe high power and torquevaluesof the dry sumpenginewhileat the sametime itistechnicallylesscomplex and thusmore economical. Also, reliabilityand fueleconomy of the new enginehasbeen improved.
