Photos of a well covered Maserati are circulating on the net. Despite the heavy cover up the prototype seems to be sporting a new front end, bigger headlamps and bigger air-intakes in what seems to be a revised front bumper. New engines with direct fuel injection to ensure better fuel economy are also expected to be added on the new Maserati. The rear was also taped which means there would be some alteration to be done on the back bumper as well. It is expected that new Porsche Panamera and Aston Martin Rapide will become the tough competition for the new Maserati Quattroporte. Unfortunately for us we will have to wait until 2012 before we finally get to see the next-generation Quattroporte.
