The A9, designed by Bertone, was the last prototype of Anadol. It was a 4-door sedan with a very modern design for early 1980s. The rear parts of the car resembled the future Peugeot 405, while the overall form resembled the Volvo sedans of the mid 1980s.

A new and more contemporary-looking Anadol logo was developed for the A9. The design of the wheels were also characteristic of the European cars of the mid to late 1980s. However, the A9 couldn't make it to full mass-production, as well as FW11 and Cagdas models and the prototype was destroyed. No information could be found about this prototype, other than the below visual materials.A9 was the last studies of Otosan under Anadol brand.

The Anadol passenger car production has been ended by Otosan in 1984. The R&D studies for the new models have been ceased. The global economic developments and the unstable domestic political and economical situations, together with the increasing oil prices forced Otosan to end up the already developped R&D studies of the new prototypes.

However, Otosan continued the manufacturing of the pick-ups (otosan 500 and Otosan 600D) until 1991. Otosan has signed another protocol with Ford Motor Company in 1984 for the production of Ford Taunus (Cortina) passenger cars. The investments in the Hasanpasa-Istanbul factory for the new production lines ended in 1985 and Ford Taunus passenger car production continued between 1985-1993. The last production of Hasanpasa Factory was Ford Escort (1993-1999).

In 1997, Ford Motor Company and Otosan signed an agreement for a joint-venture and Ford Otosan has been born. Today Ford Otosan continue the production of Transit Connect in their new plant in Golcuk-Kocaeli and Ford trucks in another plant in Inonu-Eskisehir.
