Maserati announced they will be unveiling their next generation Quattroporte at the 2013 North American Auto Show in Detroit. But prior to the show this winter, the Italian luxury brand has decided to leak this gallery of photos of the sixth generation of its iconic sports sedan, which features a lower roofline, redesigned headlamps, three side windows and an updated luxury interior with screens in the headstocks to keep backseat passengers well entertained. The 2014 Maserati Quattroporte will also feature an upgraded V8 engine, which will be produced in the Ferrari plant in Maranello. Although few technical and performance details have been shared, at least we have a good idea of the visual look of Maserati’s next 5-door halo sedan.
