In December 1990 Maserati presented the Chubasco, a two-seater sports coupe prototype foreshadowing a new top-of-the-range model.
Designed by Marcello Gandini, it is wedge-shaped, its doors are hinged upwards and we notice the rear wheel arches, as on the Shamal, and later on the Quattroporte IV launched in 1996

The Chubasco is powered by the Shamal's 3.2-litre twin-turbo dry-sump V8, boosted to 430bhp, power sent to the rear wheels via a six-speed manual gearbox and limited-slip differential.
It is also a car whose aerodynamics are very worked with air flows used for cooling and aerodynamic support.

It never got beyond the prototype stage because Fiat, then owner of Maserati, deemed the car too expensive. The prototype, however, still exists and is part of Umberto Panini's collection.
