New Maserati Quattroporte Sport GT S with 433HP to Debut in Detroit

At the 2009 North American International Auto Show in Detroit this January, Maserati will take the wraps off the sportiest Quattroporte yet. Based on the Quattroporte S, the new Sport GT S gains a more powerful version of Maserati's 4.7-litre V8 engine with a remapped ECU that delivers an output of 433HP. Maserati also updated the gearshift management software while the front and rear suspension system gets new single-rate dampers, stiffer springs and lower ride height. Other mechanical changes concern the new sport exhaust system which is controlled by pneumatic valves for a deeper and more throaty sound bite.

Cosmetic changes over the standard Quattroporte S include a new black grille with concave vertical fins featuring the Trident logo with red accents, a metallic titanium finish for the headlights, body-coloured door handles, black finishing around the doors and black twin oval exhaust pipes. Inside the sportiest Quattroporte boasts new M-design seats with perforated Alcantara and leather upholstery as well as titanium colored composite material for the trim.
