It addition to its GT coupe, Maserati offers a 4-door model, aptly named the Quattroporte. Its three trim levels are the base version , S and GT S. Each comes with its own drivetrain featuring an 8-cylinder engine. There’s nothing new to report for 2012, as this car is scheduled for an overhaul next year. Rumour has it that it will be equipped with a Pentastar engine (from Chrysler) and MultiAir technology (from Fiat). The Quattroporte rivals the Audi A8, BMW 7 Series, and Mercedes-Benz S-Class.
