When it comes to naming its models, Maserati keeps it simple. Case in point: the Quattroporte, which, as its name suggests, is a four-door sedan. Descended from a long line of high-performance cars, it comes standard with a 404-horsepower, twin-turbo V6, but a 523-horsepower V8 is also available for performance enthusiasts. All engines are paired with an eight-speed automatic transmission. The Quattroporte rivals German models like the Mercedes-Benz S-Class and BMW 7 Series.
