Maserati's Quattroporte Sport GT S, is their most powerful luxury sedan ever. The Sport GT S features four major technical and five significant stylistic improvements - increased power for the V8 4.7 liter engine to 433 HP; sportier gearshift management for a 0 – 60 time of less that 5.5 seconds; a re-engineered front and rear suspension system featuring stiffer springs and lower ride height; and a new sports exhaust system controlled by pneumatic valves for a “deep, throaty and captivating sound.”
