The IFA F9 is a car model of the industry association vehicle construction of the GDR . The car with a three - cylinder two-stroke engine was built at VEB Automobilwerk Audi Zwickau (formerly Auto Union , Audi factory ) from October 1950 to summer 1953 and then rolled off the assembly line at VEB Automobilwerk Eisenach (AWE) under the name EMW 309 until 1956 . The successor was the Wartburg 311 .

history

Even before the Second World War , the Auto Union designed the DKW F9 , which was scheduled to be launched in 1940. When the war began, the plans were put on hold for the time being. The F9 was then officially presented at the Leipzig spring fair in 1948 and built as one of the first post-war models in the GDR.

From 1949, the pre-war IFA F8 model was initially produced in the VEB motor vehicle factory Audi Zwickau (see DKW F8 ), and the F9 also went into production in Zwickau from October 1950 . The bodies were produced in the Horch factory in Zwickau , the engine came from the Chemnitz engine factory , and the cars were assembled in the former Audi factory of Auto Union. The number of units was initially limited, a total of 1920 F9 vehicles were produced in Zwickau. In 1952 a convertible from VEB Karosseriewerk Dresden (formerly Glasses Body ) was added, in the same year the engine output was increased from 28 to 30 HP. Test cars with a plastic body were produced. Development work in this direction was later not pursued any further. In the summer of 1953, production in Zwickau was ended in favor of the newly developed AWZ P70  - an F8 with a plastic body in the shape of a pontoon.

From 1953 to 1956, production at VEB Automobilwerk Eisenach was continued in significantly larger numbers under the internal name EMW 309 . From then on, the sedan had a more modern windshield and a modified rear window : the front window no longer consisted of two flat, angled parts with a central bar, but was now larger, one-piece and curved. A large one-piece panoramic rear window replaced the small rear window, which was previously divided into two. Because of the significantly enlarged windows, there was also talk of a full-view body or a full-view sedan. In the course of 1954, the continuous windshield found its way into all other body variants. The production program was supplemented by a station wagon with either a steel-wood or all-steel structure, the number of which, however, remained very small. It had reinforced springs at the rear, thicker tires 5.50 instead of 5.00, and a different translation in the front axle drive.

In 1954 the tank was relocated to the rear and enlarged from 30 to 40 liters. A more efficient heating system was installed in its previous location. Above all, modified cylinder heads reduced the engine's demands on the knock resistance of the two-stroke mixture, and a modified exhaust system dampened the noise in the passenger compartment a little better. In addition, the transmission and drive ratios have been changed. In 1955 the crutch shift was replaced by a steering wheel shift . The failure-prone central lubrication pump was converted from pressed material to zinc injection molding in 1955. In 1956 the breaker was modified to eliminate ignition problems. The equipment and accessories of the F9 had a number of minor weaknesses until the end of production. Production ended in 1956, and its successor was the Wartburg 311, which was further developed from the F9 in Eisenach . A total of around 30,000 vehicles were built by May 1956. The production of replacement bodies continued at the Dresden bodywork plant until at least 1963.

In 1955, Auto Union filed a lawsuit alleging unfair competition because the F9 was too similar to the DKW F93 and was based on construction plans that were owned by Auton Union. The explosive nature of the lawsuit was limited, however, as the F9 was replaced by the Wartburg 311 in early 1956. With regard to the further use of the engine, chassis and spare parts production, Auto Union and the GDR reached a settlement .

Trivia

The IFA F9 was the last car built in the GDR with suicide doors .

The F9 had a "sister model" - the DKW F89 built by the "new" West German Auto Union from 1950 at the Düsseldorf-Derendorf plant . The vehicles were largely identical, but the F89 had a smaller two-cylinder engine and a different grille. It was replaced in 1953 by the DKW F91 with a three-cylinder engine.
