The Maserati GranSport is a sportier version of the Coupé that was first unveiled at the March 2004 Geneva Motor Show.

It featured improved aerodynamics, retuned suspension, engine and transmission, and a sportier interior.

An open-top GranSport Spyder with similar modifications was introduced a year later, at the September 2005 Frankfurt Motor Show.

It was powered by the same 4,244 cc, dry sump, 90° V8 petrol engine used on the Coupé and Spyder. However, the engine develops 400 PS (294 kW; 395 hp) at 7,000 rpm due primarily to a different exhaust system and improvements on the intake manifolds and valve seats.

Only the six-speed Cambiocorsa paddle shift transmission was offered, and was recalibrated for quicker shifts.

The exhaust, equipped with bypass valves, was also specially tuned to “growl” on start-up and full throttle. The GranSport used the Skyhook active suspension, with a 10 millimetres (0.4 in) lower ride height.
