The sportiest to-date model of Maserati's Quattroporte range made its worldwide debut at NAIAS. The technical changes to the new Quattroporte Sport GT S compared to the 'S' model concern the mapping of the V8 4.7-litre engine which now produces 433HP, the new gearshift management software, the stiffer springs and lower ride height as well as the more sonorous sport exhaust system.The Italian firm's designers also went ahead and made a few subtle changes to the sport sedan's exterior and interior. These include the new black grille with concave vertical fins featuring the Trident logo with red accents, the new headlights, in metallic titanium finish, the new M-design seats with perforated Alcantara and leather upholstery and finally the "titanium colored" composite material dashboard trim.
