The brand aims to sell at least 13,000 of its new four-door Quattroporte sedans in 2013, priced between 100,000 euros and 150,000 euros each. This compares with a total of about 4,700 cars Maseratis sold in the first three quarters of 2012.
Maserati's new Quattroporte is the second car built from a shared car body to be launched by Fiat since the start of its 2009 tie-up with US carmaker Chrysler. It competes with the BMW 7 Series and Porsche's Panamera.
The launch is being watched by enthusiasts and investors alike to see how well Fiat executes its ambitious plan to leverage Chrysler's market access and technology to build up the Maserati brand in the United States.
While previous attempts by Fiat to grow its luxury Maserati and Alfa Romeo brands have been disappointing, the Turin-based company hopes that access to Chrysler's 2,300-store US dealer network will make it successful this time around.
The sleekly-styled new sedan is built on a Chrysler 300-derived chassis, and is powered by an engine designed and manufactured in Italy by Maserati's sister brand Ferrari.
"This is a totally different product and it speaks to a much broader customer base," said Wester when asked how he intends to meet his aggressive sales target.
The Quattroporte is built at a new Turin factory refurbished by Fiat at a cost of around 1 billion euros.
LONGER AND WIDER
Wester said he was targeting Quattroporte sales of 80,000 over the seven-year life of the new model.
Maserati will increase its dealerships worldwide to 425 by 2015, from 250 at the end of this year.
The brand had sales of 472 million euros in the first nine months of this year, up 6% from a year ago. This compared with combined Fiat-Chrysler revenues of 62.14 billion euros for the period.
Later next year, Maserati will launch a smaller sedan called the Ghibli, priced at between 50,000 to 100,000 euros. A new sports utility vehicle, the Levante, likely to be made at the Fiat factory Mirafiori in Turin, will follow in the third quarter of next year.
The new Quattroporte has been completely redesigned, said Lorenzo Ramaciotti, head of design centre Centro Stile Fiat.
This new version of the Maserati 1963 classic has a four-wheel drive, which should also help to appeal to drivers in Canada, Russia and Scandinavia, Wester said.
It comes in V6 and V8 versions. At 5.26 metres it is longer and wider, meaning it can also be chauffeur driven, and is 20% more fuel efficient than the model it replaces because 35% of its body is made of aluminium, according to the presentation on Monday.
