Even though the world premiere of the 2013 Maserati Quattroporte is a few days away, the first review of its new version has already surfaced the web. With two engine choices, the new Quattroporte (2013) hopes to earn the hearts and wallets of even more customers than before. Maserati is going to sell the 2013 Quattroporte with either a 404 hp 3.0-liter twin-turbo V6 engine or a 523 hp 3.8-liter twin-turbo V8 one. Its price list has not been announced yet.
