In 2009, Porsche entered an agreement with Volkswagen to create an 'integrated working group' by merging the two companies' car manufacturing operations.

[12] The name is short for Ferdinand Porsche's full title in German, Doktor Ingenieur honoris causa lit.

[14] Initially, the company offered motor vehicle development work and consulting,[5] but did not build any cars under its own name.

Ferdinand lost his position as chairman of the board of management of Volkswagen, and Ivan Hirst, a British Army major, was put in charge of the factory.

[20] The prototype car was shown to German auto dealers, and when pre-orders reached a set threshold, production (with aluminum body) was begun by Porsche Konstruktionen GesmbH, founded by Ferry and Louise.

Porsche's company logo stems from the coat of arms of the Free People's State of Württemberg of Weimar Germany of 1918–1933, which had Stuttgart as its capital.

Württemberg-Baden and Württemberg-Hohenzollern both in 1952 became part of the present Bundesland of Baden-Württemberg after the political consolidation of West Germany in 1949, but the old design of the arms of Württemberg lives on in the Porsche logo.

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 a fair amount of success in motor-racing with various models including the 550 Spyder, and with the 356 needing a major re-design, the company launched the Porsche 911: another air-cooled, rear-engined sports car, this time with a six-cylinder "boxer" engine.

Company leader Ferry Porsche took his son's drawings to neighbouring chassis manufacturer Reuter.

Louise's son and Ferry's nephew Ferdinand Piëch, who was responsible for mechanical development of Porsche's production and racing cars (including the very successful 911, 908 and 917 models), formed his own engineering bureau, and developed a five-cylinder-inline diesel engine for Mercedes-Benz.

The first chief executive officer (CEO) of Porsche AG was Ernst Fuhrmann, who had been working in the company's engine development division.

He was then replaced in 1988 by the former manager of German computer company Nixdorf Computer AG, Arno Bohn, who made some costly miscalculations that led to his dismissal soon after, along with that of the development director, Dr. Ulrich Bez, who was formerly responsible for BMW's Z1 model, and was CEO of Aston Martin from 2000 to 2013.

[22] In 1990, Porsche drew up a memorandum of understanding with Toyota to learn and benefit from Japanese lean manufacturing methods.

Wiedeking took over the chairmanship of the board at a time when Porsche appeared vulnerable to a takeover by a larger company.

[25] Designed by architectural firm HOK, the headquarters will include a new office building and test track.

"[33] In August 2022, Bloomberg News reported that Porsche has lined up interest in subscription of its initial public offering for a valuation between US$60–85 billion.

In August 2009, Porsche SE and Volkswagen AG reached an agreement that the car manufacturing operations of the two companies would merge in 2011, to form an "Integrated Automotive Group".

[41] In 2018, Porsche acquired a 10% minority shareholding stake of the Croatian electric sportscar manufacturer Rimac Automobili to form a development partnership.

[4] As part of the preliminary offering, 113,875 thousand shares were sold at the upper limit of the price range - 82.5 euros.

[45] In April 2022, Porsche Australia announced they are planning to open an efuel manufacturing facility in the island state of Tasmania.

The facility is to be named the HIF (Highly Innovative Fuels) Tasmania Carbon Neutral eFuel Plant.

[46] The headquarters and main factory are located in Zuffenhausen, a district in Stuttgart, where Porsche produces flat-6 and V8 piston engines.

[47] Cayenne and Panamera models are manufactured in Leipzig, Germany, and parts for the SUV are also assembled in the Volkswagen Touareg factory in Bratislava, Slovakia.

An Irish green Carrera S was built for the celebration, and it will be taken on a global tour before becoming a permanent exhibit at the Porsche Museum in Stuttgart.

[89] The current Porsche model range includes sports cars from the Boxster roadster to their most famous product, the 911.

Also a plug-in hybrid model called the Panamera S E-Hybrid was released in October 2013 in the United States[91][92] and during the fourth quarter of 2013 in several European countries.

In 2007, Porsche was expected to construct no fewer than 275 dedicated race cars (7 RS Spyder LMP2 prototypes, 37 GT2 spec 911 GT3-RSRs, and 231 911 GT3 Cup vehicles).

In a survey conducted by the Luxury Institute in New York, Porsche was awarded the title of "the most prestigious automobile brand".

[111] Porsche's 911 has been officially named by the TÜV (Technischer Überwachungsverein; Technical Inspection Association) as Germany's most reliable car.
