Maserati's Quattroporte (which translates literally to "four door") is the larger of the Italian automaker's two sedans, serving as the big sibling to the compact Ghibli. The current sixth-generation model was introduced for 2013, and it sees a light face-lift for 2021. It competes with other full-size luxury sedans including the Porsche Panamera, Audi A8, BMW 7 Series, and Mercedes-Benz S-Class.
We've described the Quattroporte as "a Maserati first and a full-size luxury sedan second." It's missing some of the more opulent features we've come to expect—massaging seats, acres of rear legroom, a panoramic moonroof, heated armrests, etc.—but what it lacks in ultimate luxury this Italian makes up for with sporty character.
One of the aspects that stood out in our 2016 First Test was the sing-song engine note of Maserati's twin-turbo V-6. We regularly found ourselves stabbing the go pedal for fun, and the powerplant never hushes into the background the way some of the Germans do. The six-cylinder model didn't leave us wanting for power, either; it happily roasted the rear tires with traction control disengaged. That said, the automatic transmission selector feels vague, and we occasionally missed the position we were aiming for.
The Quattroporte launched with an infotainment system with an 8.4-inch screen that felt ill-fit for a six-figure luxury sedan, but that issue seems to be corrected with this year's new 10.1-inch screen. Maserati made some interior updates this year, too, which may address our concerns over Chrysler-grade plastics. Less rear seat space than the competition remains an issue for those who frequently carry adult passengers in the back. For a driver's full-size luxury sedan, though, this Quattroporte is hard to beat. Unless you're armed with a Porsche badge, that is.
The Quattroporte is offered with six- and eight-cylinder engine options. For 2021, the V-8 gets more power. Both engines are paired with an eight-speed automatic. Six-cylinder models feature a 3.0-liter twin-turbo V-6 developing 424 hp and 428 lb-ft of torque, which is routed to the rear wheels as standard or to all four wheels in the Quattroporte S Q4.
When we tested a 2016 RWD example with a less powerful tune on the V-6 (404 hp and 406 lb-ft), it completed the 0-60 sprint in 4.4 seconds. Fuel economy numbers for the 2021 Quattroporte V-6 come in at 16/24 mpg city/highway with either drive type.
The new-for-2021 Quattroporte Trofeo ditches the V-6 for a Ferrari-built racehorse of a 3.8-liter twin-turbo V-8. It generates 580 hp and 538 lb-ft of torque and is available exclusively with RWD. Maserati claims 60 mph should come in just 4.2 seconds, and Trofeo models are EPA-rated at 13/20 mpg.
Maserati includes a host of driver assist active safety features on every Quattroporte. Adaptive cruise control, lane keep assist, a 360-degree camera system, blind-spot monitoring, traffic sign recognition, and forward collision warning with automatic emergency braking are all standard.
The Quattroporte includes seating for five with 42.1 inches of legroom up front and 35.0 inches in the rear. That latter number doesn't compare favorably to the 44.3 and 44.4 inches of rear legroom offered in the Audi A8 and BMW 7 Series. At 18.7 cubic feet, though, the big Italian's trunk space exceeds those of its German rivals.
Tech is one of the headlines for the Quattroporte this year; all examples swap last year's 8.4-inch display with a new 10.1-inch touchscreen running a new Android-backed infotainment interface. Apple CarPlay, Android Auto, and GPS navigation are still standard, as is a 7.0-inch display in the instrument cluster. Harman Kardon 10-speaker audio is included, and a 15-speaker Bowers & Wilkins system is available as a standalone option.
