The Maserati GranSport is a modified version of the Coupé and Spyder that was first unveiled at the 2004 Geneva Motor Show. It is equipped with aerodynamic body cladding, a chrome mesh grille, carbon fiber interior trim, and special 19-inch (480 mm) wheels. It uses the Skyhook active suspension, with a 0.4 inch (10 mm) lower ride height, and the Cambiocorsa transmission is recalibrated for quicker shifts. The exhaust is also specially tuned to "growl" on start-up and full throttle.
It is powered by the same 4244 cc, 90° V8 petrol engine used on the Coupé and Spyder. However, the engine develops 400 PS (294 kW; 395 hp) at 7000 rpm due primarily to a different exhaust system and improvements on the intake manifolds and valve seats. A six-speed paddle shift transmission comes as standard. The car is 178.1 inches (4,520 mm) long, 71.7 inches (1,820 mm) wide, 51.0 inches (1,300 mm) high and weighs 3,704 pounds (1,680.1 kg).
