Zuffenhausen-based company, Reutter Karosserie, which had previously collaborated with the firm on Volkswagen Beetle prototypes, to produce the 356's steel body. In 1952, Porsche constructed an assembly plant (Werk 2) across the street from Reutter Karosserie; the main road in front of Werk 1, the oldest Porsche building, is now known as Porschestrasse. The 356 was road certified in 1948.
Porsche's company logo was based on the coat of arms of Free People's State of Württemberg of former Weimar Germany, which had Stuttgart as its capital and became part of Baden-Württemberg after the political consolidation of West Germany in 1949.
Not long afterwards, on 30 January 1951, Ferdinand Porsche died from complications following a stroke.
In post-war Germany, parts were generally in short supply, so the 356 automobile used components from the Volkswagen Beetle including its internal combustion engine, transmission, and suspension. The 356, however, had several evolutionary stages, A, B, and C, while in production, and many Volkswagen parts were replaced by Porsche-made parts. The last 356s were powered by entirely Porsche-designed engines. The sleek bodywork was designed by Erwin Komenda who also had designed the body of the Beetle. Porsche's signature designs have, from the beginning, featured air-cooled rear-engine configurations (like the Beetle), rare for other car manufacturers, but producing automobiles that are very well balanced.
In 1964, after some success in motor-racing, namely with the Porsche 550 Spyder, the company launched the Porsche 911 another air-cooled, rear-engined sports car, this time with a six-cylinder "boxer" engine. The team to lay out the body shell design was led by Ferry Porsche's eldest son, Ferdinand Alexander Porsche (F. A.). The design phase for the 911 caused internal problems with Erwin Komenda, who led the body design department until then. F. A. Porsche complained Komenda made unauthorized changes to the design. Company leader Ferry Porsche took his son's drawings to neighboring chassis manufacturer Reuter. Reuter's workshop was later acquired by Porsche (so-called Werk 2). Afterward Reuter became a seat manufacturer, today known as Keiper-Recaro.
The design group gave sequential numbers to every project (356, 550, etc.),
