Maserati Quattroporte MY13 Power Increase


2012 Maserati Quattroporte S and Sport GT S (4.7 l, M139, MY13) received a Power Increase package along with the new GranTurismo Sport. Thanks to optimising the engine mapping, increasing the valve overlap above 5,500 rpm thanks to VVT system and optimal use of timing advance. All this resulted in increased performance in SPORT mode above 5,500 rpm (+10 PS and +20 Nm). New F136 YR and YT engine codes were assigned to this update. Production of M139 also ceased in 2012.
