Maserati Quattroporte

The new Quattroporte -- Maserati's flagship model -- is larger, lighter, more luxurious and more practical than previous versions, the company says. With a 307 km/h top speed, it's also as fast as most two-door super cars.

The powerful Maserati engines and large cabin are core to the Quattroporte's design. Dominated by a long, powerful nose and a concave Trident grille, the new Quattroporte boasts a 530 hp twin turbo V8 -- making it not only the fastest four-door Maserati has ever built, but also the most powerful and fuel efficient, company officials said.
