In simple terms, the GranLusso is a more luxurious version of a trim level, while the GranSport is more performance-oriented. The range-topping GTS has no base version; just choose between the GranLusso and GranSport. Whatever your package preference, the Quattroporte is a stylish and attractive choice — especially when you hear the soundtrack from the two available engines.

At the bottom of the trim-level ladder, you've got the Quattroporte S, which comes with a twin-turbocharged 3.0-liter V6 (404 horsepower, 406 pound-feet of torque); an eight-speed automatic transmission (attached to rear-wheel drive); 19-inch wheels; adaptive automatic xenon headlights; automatic wipers; LED running lights and taillights; heated, power-folding auto-dimming mirrors; a sunroof; front and rear parking sensors; blind-spot monitoring; remote start; an adaptive suspension; and keyless entry and ignition.

On the inside, you get dual-zone automatic climate control, a rearview camera, heated and power-adjustable front seats, driver-seat memory functions, a folding rear seat, a power-adjustable steering wheel, wood interior trim, power rear side-window sunshades, ambient interior lighting, Bluetooth, a new 8.4-inch touchscreen, a navigation system, a Wi-Fi hotspot and a 10-speaker Harman Kardon sound system.

For the Quattroporte S, the GranLusso package adds to the standard equipment with 20-inch wheels, chrome exterior trim, black brake calipers, ventilated front seats, power-adjustable pedals, a wood and leather steering wheel, premium interior leather upholstery, a simulated-suede headliner, a power rear sunshade, forward collision warning and mitigation with emergency braking, adaptive cruise control, a surround-view camera and lane departure warning.

The GranSport offers a more performance-oriented vibe by building on the base S trim with unique 20-inch wheels, a black grille, black side skirts, red brake calipers, a sport steering wheel, sport front seats and paddle shifters on the steering wheel.

The Quattroporte S Q4 is a small step up from the standard S, and it adds all-wheel drive, a power trunklid, shift paddles, heated rear seats and a heated wood and leather steering wheel. The GranLusso and GranSport packages essentially add the same equipment to the S Q4 that they do with the base S trim.

At the top of the trim-level list is the Quattroporte GTS which gets the 3.8-liter turbo V8 (523 hp, 524 lb-ft), rear-wheel drive and some GTS badging. With the GTS, you are required to choose between the GranLusso and GranSport, which add basically the same equipment as they do on the lower trim levels.

As with most other luxury sedans in this class, there are a lot of additional options to choose from. If you're so inclined, you can get equipment including 21-inch wheels, four-zone automatic climate control, an array of wood and carbon-fiber interior trim pieces, folding rear-seat tables, a rear center console in place of the center seat (dropping passenger capacity from five to four), a rear-seat entertainment system and a Bowers & Wilkins premium audio system. Most of the upper trim-level equipment can be added as stand-alone items on lower trim levels.
