Citroën’s ownership of Maserati was problematic for both companies. The French plan for the second-generation Quattroporte was to share the V6 drivetrain with the Citroën SM. The design was by Bertone but a front wheel drive Maserati with a slow V6 rather than a V8 wasn't what the market was looking for. Only 13 cars were completed with prototype construction starting in 1974. The Quattroporte II was never fully homologated for sale, so all sales where in markets where homologation wasn't required: Saudi Arabia, Qatar, and Spain (not part of the EU at the time). It helped to drive Citroën into bankruptcy and Maserati into the hands of Alejandro de Tomaso.
