The sixth generation Quattroporte luxury sports sedan from Maserati is set to be unveiled at the upcoming Detroit Auto Show in mid-January of 2013. While preliminary photos reveal a silhouette car enthusiasts have come to expect from the Italian dynamo, specs are being withheld at this point – although car insiders point to the BMW 7-Series, Mercedes-Benz S-Class and Jaguar XJ as the Quattroporte’s main rivals. Head of the Maserati Design Center, Lorenzo Ramaciotti, explained, “Its style was born out of the guiding design principles of Maserati: harmony of shapes, dynamism of lines and Italian elegance. More generous in size when compared to the previous model, the new Quattroporte has a design that is at once graceful and sinuous, fashioned to bring out the sporty nature of the car.” According to Maserati, the 2014 Quattroporte will be powered by an all-new, next generation powertrain designed and developed by Maserati and Ferrari engineers and built at Ferrari’s Maranello plant. Expect more details as they become available.
