The Maserati Quattroporte is a luxury four-door sedan made by Maserati of Italy. The name translated from Italian literally means "four doors". There have been five generations of the car, each separated by a period of roughly five years. The Maserati Quattroporte is offered in four configurations: the base Quattroporte, the Quattroporte Sport GT, the Quattroporte Sport GTS, and the Quattroporte Executive GT.

Only 5,700 Quattroportes were made in 2006.[4] In 2009, the Aston Martin Rapide will be the Quattroporte's main rival as the market, trim, and exclusivity will be very similar, although it will be powered with a V12 engine and will be much more expensive. Also in 2008/2009 the Porsche Panamera will be on sale, creating more competition to the high-end luxury saloon segment.
