Maserati has unveiled a new flagship Quattroporte – the Sport GT S. It gets altered gearbox management software, a remapped ECU to boost power by 8bhp to 433bhp and a new throatier sports exhaust.
The front and rear suspension has been revised featuring single-rate dampers, stiffer springs and lower ride height. Visually the car is more aggressive with a new black concave grille, titanium-finish headlamps, black finishing around the doors and new M-design seats in Alcantara.
The new Quattroporte Sport GTS will be unveiled at the 2009 NAIAS in Detroit.
