Maserati celebrates its 70th anniversary and first Indy victory with a new variant of their original big-boys sedan. The Maserati Quattroporte Sport GT S ($140,000) features a recalibrated V8 4.7 liter engine, boosting power to 433 hp that can launch the Italian beauty from zero to 60 in less than 5. 5 seconds. The Sport GT S interior receives new M-design seats with Alcantara and leather trim, while the exterior gains a black grille complete with a chrome trident logo with red accents as well as black finish to the door pillars, belt line, door handles and exhaust pipes.
