We're still a few years out from seeing an all-new sedan from Maserati, but the firm did spiff up its 2009 Quattroporte with a few changes.

Perhaps the most significant addition is the new Quattroporte S model. More than an attempt to look sporty, the S makes use of the same 425-hp 4.7-liter V-8 found in the slinky GranTurismo S coupe, while base models make use of the carryover 4.2-liter V-8, good for 400 hp. Regardless of the engine, a ZF-sourced six-speed automatic is standard fare.

Other changes to the '09 Quattroporte are much more subtle. Maserati's left much of the original Pininfarina design unchanged, only to refine small details. For instance, the 2009 cars now sport LED lighting in both the front turn signals and rear lamps, along with a new grille (with vertical slats) and tweaked bumper skins.

Interior modifications are likewise limited, consisting of a new navigation and audio system and two new shades of leather seating.

Look for both the 2009 Quattroporte and Quattroporte S to arrive in dealers worldwide in the fall of 2008.
