Maserati's goal is to expand its global sales from 6,300 in 2012 to more than 50,000 by 2015, said Maserati CEO Harald Wester.
After the Quattroporte was unveiled, Wester was joined on stage by Chrysler and Fiat CEO Sergio Marchionne and Fiat Chairman John Elkann.
Elkann's presence on stage, as a member of the Agnelli family that founded Fiat, underscores the importance of the launch of the redesigned Quattroporte.
Wester said Maserati expects to achieve that by launching three new products globally and in the U.S. including the new Quattroporte this year, the Ghibli midsize sedan at the end of this year and the Levante small SUV by the end of 2014.
Together, those three products will make Maserati "a genuine global player," Wester said.
The sixth-generation Quattroporte unveiled Monday is a model "which will once again shape Maserati's future," Wester said.
The all-new Quattroporte luxury sedan brings Italian style and performance to a market for $100,000-plus cars that German brands have dominated.
With industry sales in Italy sinking to their lowest level since 1979, Fiat has launched a major reorganization plan that hinges on boosting exports of luxury models from Italy to prevent plant closings.
Marchionne's plan is to sell more Maserati, Alfa Romeo, Jeep and Fiat 500 cars in the U.S. and other growing markets to stem Fiat's losses in Europe.
But last year in the U.S., Maserati sold only 630 Quattroportes and only 2,730 vehicles of all its models, while both BMW and Mercedes-Benz approached nearly 300,000.
Maserati has yet to announce a price for the Quattroporte in the U.S. market.
The redesigned Quattroporte, which will go on sale by June, gets its power from a pair of direct-injection, twin-turbo engines engineered by Maserati and built by Ferrari.
The 3.0-liter V6 produces 404 horsepower and 406 pound-feet of torque and accelerates to 62 m.p.h. in 4.9 seconds and reaches 177 m.p.h.
The 523-horsepower 3.8-liter V8 generates 523 pound-feet of torque, hits 62 m.p.h. in 4.9 seconds and tops out at 191 m.p.h.
The V8 Quattroporte is faster, more powerful and 20% more efficient than the outgoing model.
The interior is available in four- or five-seat configurations. Other features include WiFi, an 8.4-inch touch screen and a 15-speaker, 1,280-watt Bowers and Wilkins audio system. Maserati builds the Quattroporte in a new plant in Turin, Italy.
