La Maserati GranTurismo est une automobile de grand tourisme du constructeur automobile italien Maserati, présentée en mars 2007 au Salon international de l'automobile de Genève. Même si la GranSport est restée quelques mois en production, la nouvelle venue a in fine pris sa place. La GranTurismo a été dessinée par Sergio Pininfarina. Trois versions ont vu le jour ; la GranTurismo, la GranTurismo S et la GranTurismo S Automatic. La première dispose d'un moteur Moteur V8 4,2 L, ouvert à 90° et fort de 405 chevaux pour un couple de 460 Nm. La transmission passe par les roues arrière via une boîte automatique ZF à six rapports. Son poids est annoncé à 1 780 kg. En avril 2008, une définition S de la GranTurismo a été développée et se caractérise par une puissance portée à 440 chevaux. La cylindrée passée, pour ce faire, à 4,7 litres (4 691 cm³), permet à la voiture de descendre à 4,9 secondes pour le 0 à 100 km/h et d'atteindre une vitesse de pointe de 295 km/h.
