In the 1950s the bodies for the Porsche 356 were built and fully painted at the Reutter factory and then delivered with windows and interior equipment. Porsche subsequently undertook fitting of the engine and running gear. In 1964, Porsche purchased the Reutter carbody factory. This meant that for the first time Porsche was in possession of an independent automobile factory.
In 1969, vehicle assembly moved into the newly built multistory building on Schwieberdinger Straße. At that time, vehicle interior equipment was fitted on the third floor. Installing the engine and bolting together the running gear followed on the second floor.
In 1979, a second production line was introduced for the production of the Porsche 928.
This was the first time that a hanger system was used in running gear installation, which was adopted for the Porsche 911 a short time later. At the beginning of the 1980s, Porsche converted to movement on skids on the third floor. The assembly process was still executed on a static vehicle. However, at the end of the cycle assemblies were forwarded automatically within the respective production section. In the meantime, production technology at Porsche has been developed further so that the Boxster and 911 are now both assembled using the mixed-model system on a continuous line.
Since 1987, bodies welded previously in the main plant have been transported from a newly erected body shell production site over a bridge to the paint shop and then fed to the assembly hall.
