The Maserati GranTurismo is an upcoming grand tourer to be produced by Italian automaker Maserati. It was officially presented at the Geneva Motor Show in March 2007. The GranTurismo is a two-door 2+2 coupé. Many design elements come from the Ferrari 599 GTB Fiorano, which is also a grand tourer.

The engine is the same Ferrari-sourced 4.2-litre (4244 cc) unit which is currently used in the Coupe, Spyder, GranSport and Quattroporte, although uprated to a maximum output of 405 hp. The GranTurismo uses a dry sump and the transmission is located in the front of the vehicle, as opposed to a wet sump and a rear-mounted transmission used on Duo Select models of the Coupé and Quattroporte. The dry sump method is also featured on the up-and-coming Maserati Quattroporte Automatica. Given the location of the transmission, the Automatica still boasts a 49/51 front/rear weight distribution — extraordinary for a front-engined car. There is speculation that a GranSport model will carry a 470 bhp 4.7-litre V8 from Alfa Romeo's 8C Competitizione.

At the Barcelona Motor Show Maserati previewed a 4.5-litre V8 version of the GranTurismo, which could be accompanied by a new version of the CambioCorsa transmission, or the same 6-speed automatic found in the 4.2-litre version (base model) and the Quattroporte Automatica. It is also rumored to have approximately 500bhp.
