The new car, which is codenamed M156, will use an updated version of the current 4.7-litre V8 - massaged almost inevitably for better fuel economy and emissions figures - while the styling is expected to be influenced by the look of the GranTurismo.
But an all-new Quattroporte isn't the only new Maserati on the way. The company has bold ambitions to push sales to 20,000 units a year (last year it managed 5675 cars, while its record year was 2008, with just under 8600 cars built) and to help it achieve this it plans to add a smaller saloon to the range in 2014.
This car - known in Maserati-speak for now as the M157 - will eventually take on the higher echelons of the BMW 5-series and Mercedes E-class market segments, while the new Quattroporte will be pushed a little further upmarket than the current model.
All of which is excitingly ambitious, but it does leave us with one burning question unanswered: if the Quattroporte name means simply 'four-door', what will Maserati call the smaller saloon?
