The most important technical evolution for the Quattroporte came with the introduction of an automatic version at the 2007 Detroit Motor Show. While the Quattroporte with Duoselect transmission has proven to be an ideal match for Maserati’s sporty reputation, demand for a fully automatic version had always been present. The Quattroporte Automatica is much more than a Quattroporte simply fitted with a new gearbox. From the 16,500 components of which the Quattroporte is made, 4,800 are new. The powertrain is completely new with the adaption of a new wet sump engine (F136UC), 6-speed automatic gearbox from ZF, propeller shaft and limited slip differential. The Quattroporte Automatica is available in standard version as well as Sport GT and Executive GT. The Sport GT was later on replaced by the more expressive Sport GT S.
