As from the 1976 model year the Taunus and Cortina were almost identical, apart from regional variations (in terms of specification changes and trim levels). Internally, they were defined by the setting of the driver´s place – LHD (left-hand drive) cars were badged Taunus while RHD (right-hand drive) cars were badged Cortina, disregarding the country of origin.
However,in Israel,the left Lhd Taunus was sold as the Cortina (imported from UK) until 1981 when it ceased production,but a certain amount of cars from Germany arrived and was sold in Israel as the Taunus.
The major components of the European Taunus “TC2″/”TC3” and Cortina Mk 4 (of the 1979-82 series often referred to as Mk 5 although that has never been the official term)remained basically the same through the entire production run only receiving minor body changes with the biggest re-engineering in the 1979 model year, which involved a facelift (identical to the Ford Cortina Mk 5 update).
The Taunus TC along with the Cortina Mk III and their successors have been produced in slightly updated forms in Europe, Argentina and widely across Asia by Ford or their local co-operators. Cortinas were also built in small numbers starting with the predecessor Cortina Mk II throughout the model serie´s European/east Asian lifespan under license by Korean automaker Hyundai. This led to the Cortina 80 at the end of its production life serving as a starting point for the first Hyundai Stellar which succeeded the Cortina line in South Korea, handing over some major technical components such as the steering rack and the transmission propelling shaft to the otherwise non-Ford successor. Meanwhile, the European production tools for the Taunus TC3 4-door sedan was shipped to Turkey for a new lease on life as the Ford-Otosan Taunus beginning production in late 1983. At the closing of the eighties it had evolved visually from its all-western origin to the point that it took on a slightly new persona as the Taunus 2000, later on badged Taunus GLS for the top-of-the-line. Engines were the ordinary 1.6 or 2.0 OHC backed by a four- or five-speed manual gearbox, but the front and back ends were by now reworked with styling cues from newer European Fords and a quite luxurious new interior. The last Turkish Otosan-Taunus left the factory in 1994.
The Taunus/Cortina was replaced in Europe by the Sierra in late 1982. The Sierra carried over the Cortina/Taunus OHC Pinto Engines and RWD configuration but was otherwise an all new car with independent suspension all round.
The Taunus and Cortina models are very easy to service and share a lot of mechanical components with the other European Ford cars of the period (excluding the Ford Fiesta), making them extremely easy to fix, although they are now a rare sight in even the markets where they were most popular. For example, the British Cortinas of this generation sold more than 1,000,000 units, but little more than 2,000 were in circulation by 2006. The Taunus, however, still can be seen in circulation, in nations like Spain, Germany and Scandinavia and there is an active owners club.
In 1982 production of the Taunus ceased in Europe; it was replaced by the Ford Sierra. Production continued in Argentina until 1984, where a fastback coupé version remained in the line-up right until the end (while in Germany the coupé was dropped after the 1975 facelift), and at Otosan in Turkey, where a restyled version of the last model continued in production until 1994.
