Marcello Gandini
In 1994, the aging Quattroporte III/Royale was replaced by the Quattroporte IV which was ultimately based on Biturbo underpinnings. Styled by Marcello Gandini, it was initially available with a V6 engine shared with the Ghibli II. A more powerful V8 variant was made available in 1996 and "Seicilindri" and "Ottocilindri" (six and eight cylindres in Italian) badging was introduced to distinguish between the two models. The engine of the V8 model was a development of the Shamal's V8.
