The SP FFX is a 2013 one-off based on the Ferrari FF. Instead of the shooting brake rear of the FF, which offers up to 800 liters of trunk capacity with the rear seats folded down, it features a bespoke body with a coupe-like tail. Commissioned by a customer from Japan, Ferrari's Special Projects division built it to a design by Pininfarina. Early patent drawings led to speculation that it might be the design for the next California.
