The Quattroporte offers two-door Italian exotic performance with four real doors and more than serviceable back seat accommodations. It is powered by a 4.3-liter Ferrari-sourced V-8 rated at 393 horsepower, with a six-speed, clutchless, “Duo-Select” manual transmission the standard gearbox. This transmission can function in full automatic mode, like a conventional fluid-drive automatic; in manual mode, the driver has full control of shifting operations, while a computer and electric servos engage and disengage the clutch. As Maserati’s most luxurious model, the Quattroporte comes standard with an active suspension system, premium Bose audio system, xenon HID headlights, and DVD navigation. A Sport GT package adds 20-inch wheels, more aggressively calibrated shifting characteristics for the six-speed transmission, drilled brake rotors, sport-tuned exhaust, and carbon fiber trim, among other upgrades. An Executive package adds Alcantara suede trim, rear climate control, heated and massaging seats, pull-down dining trays for rear seat occupants, and a DVD entertainment system.
