Much like the GranTurismo, the two model grades include the standard Quattroporte and more powerful Quattroporte S.
The former features a familiar 4.2-litre 298kW V8 engine whilst the latter model adopts the new 4.7-litre 320kW V8 engine as introduced in the GranTurismo S.
Both models feature a six-speed automatic transmission developed in association with ZF.
Exterior styling changes to the new Quattroporte are minimal, comprising of a new grille with vertical slats reminiscent of the GranTurismo, more prominent side mouldings, new rear bumpers and new front and rear lights featuring LED technology.
The interior has received a far more generous update, with a new centre console featuring a more ergonomic control layout as well as a fully updated navigation system as part of the new Maserati Multimedia system.
There are also two new shades of leather on offer: Marrone Corniola (Brown) and Sabbia (Sand), replacing the beige which was previously in the range.
The Maserati Quattroporte will make its Australian and New Zealand public debut at the Australian International Motor Show in October, with deliveries starting early 2009.
Existing owners will also be treated to a private viewing prior to the public launch.
