In this final stage of production, the doors are removed first and completed in a separate line. At the same time, the bodywork is given its interior - this is where industrial production and craftsmanship merge. Once the interior has been installed, the finished vehicle changes its means of transport: instead of the lifting table used until then, a rotating hanger is used to install the brakes and fuel tank, which enables ergonomic working. With the following exterior line, the vehicle runs on a lifting table again, which also ensures ergonomic working thanks to its height adjustability. The exterior line includes, for example, the installation of the windscreen, rear window, headlights and seats. The doors are also refitted and the Porsche crest is attached. This is followed by the big moment in the assembly process: the marriage. The marriage is the fully automated joining of the body with the completed powertrain. After the engine wiring, final work such as filling with fuel, brake fluid, coolant and windscreen cleaner takes place on the final assembly line. The wheels are also fitted at this point. The final assembly cycles are used for commissioning, testing and final inspection of the vehicle. After a test drive, final acceptance takes place and the vehicle finally leaves production. An important quality assurance measure is the audit, in which individual vehicles of all model variants are randomly subjected to a more comprehensive inspection. The vehicles are delivered all over the world. Around 75 per cent of the vehicles from the Porsche plant in Leipzig are transported by environmentally friendly rail - powered by 100 per cent green electricity.
