Currently working on a Turkish series, I was wondering about how some Tofas-built Fiat models should be considered in terms of model origin. For what I see, we currently consider of Turkish origin only the Tofas-branded models Dogan, Sahin and Kartal as local iterations of the Fiat 131.

Tofas has got an own R&D center since 1994, and their most notable works so far are:

- collaboration on the Brazilian-guided Project 178 (Palio/Siena)
- collaboration on the Fiat Doblò [223] development, whose intellectual property rights were acquired by Tofas while working on its 2006 facelift
- local iteration of the Project 178 as the Fiat Albea, a facelifted and stretched version of the Siena
- "Minicargo Project", guided by Tofas (who owns the intellectual property rights) for Sevel, producing the Turkish-built Fiat Fiorino/Qubo [225] and PSA-twins Citroen Nemo and Peugeot Bipper
- collaboration on Project 323, a saloon-version of the Fiat Grande Punto [199] sold worldwide as Fiat Linea (engineering by Tofas and styling by Fiat)
- development of the second Fiat Doblò generation [263], later sold also as Opel/Vauxhall Combo and Ram ProMaster City
- "Egea Project", guided by Tofas (responsible for the development and owner of the intellectual property rights) for a new C-segment model, launched in 2016 as saloon, hatchback and wagon, and marketed as Fiat Egea in Turkey, Fiat Tipo in Europe and Dodge Neon in Mexico

All these informations are available on the Tofas site https://www.tofas.com.tr

That said, in my opinion following models could deserve a Turkish origin:
- Fiat Albea
- Fiat Doblò [263] and its twins Opel Combo D, Vauxhall Combo Mk.3 and Ram ProMaster City
- Fiat Fiorino/Qubo [225] and its twins Citroen Nemo and Peugeot Bipper
- Fiat Egea/Tipo and the rebadged Dodge Neon for MEX

Not sure about the Fiat Linea: according to the site, engineering was done by Tofas and styling by Centro Stile Fiat, but nothing more precise is said
