History

[edit]

Formation

[edit]

In 1920, engineer and pilot Hellmuth Hirth established a small workshop in Bad Cannstatt with others, where he developed and constructed a two-stroke engine.[4] 26-year-old Hermann Mahle started working for Hirth on 1 December 1920 as his seventh employee. The workshop was then called Versuchsbau Hellmuth Hirth.[a] 1 December 1920 is acknowledged as the birth date of today's Mahle Group.

It soon became clear that the workshop would not survive by only conducting engine tests, so the need arose to build a profitable line of production in order to finance ongoing engine tests. At that time, pistons in automotive engines were generally made of cast iron, but Versuchsbau Hellmuth Hirth experimented with light alloy pistons.

On 1 November 1922, Hermann's brother Ernst joined the factory as head of engineering. In 1924, the company merged with Chemische Fabrik Griesheim-Elektron, the inventors of the magnesium alloy Elektron,[5] and was renamed Elektronmetall GmbH.[6]

In 1927, the company developed Germany's first controlled-expansion piston, and in 1931, the world's first aluminium ring carrier piston for diesel engines. Following this, piston technology was steadily improved. In 1931, aero engine manufacturing was split off as a separate company, Hirth Motoren GmbH.[7]

In 1938, Elektronmetall became Mahle KG, and a new company logo was introduced. The company expanded, and before World War II was the only company in Germany manufacturing die-cast magnesium alloy products.[8] During the war, the company's Bad Cannstatt factory made alloy pistons ranging from those for small cars to pistons with a 40 cm (15.7 in) bore for submarine engines (such as the 522 L (31,854 cu in) diesel MAN M9V 40/46). The Fellbach plant accounted for 70% of Germany's output of magnesium, aluminium and zinc alloy pressure die castings.[9] After 1945, new products were developed and produced (such as aluminium cylinders with Cromal surface coatings in 1951).

In 1964, Hermann and Ernst Mahle decided to waive private ownership in their company and make it part of a foundation for public benefit. They transferred the company shares to the Mahle Foundation.

In 1976, Mahle made the first series-production aluminium engine blocks in Europe using low-pressure die casting. In 1988, their composite camshaft was enhanced to production standards, and in 2001, they developed a cooling system for diesel engine pistons in high-speed passenger cars. The first all-plastic oil filter in the world followed in 2003. Mahle developed and constructed its first complete engine in the same year, which was used in Formula Student.

Mahle has become a predominant system supplier for components of piston systems, cylinder components, valvetrain systems, air management systems, and liquid management systems. The Mahle Group generated sales in excess of €5.2 billion in 2010, and in excess of €12.8 billion in 2017.

History

Founding and early development

Mahle GmbH originated on December 1, 1920, in , , when Hermann Mahle, a businessman, joined the workshop Versuchsbau Hellmuth Hirth, founded by engineer and aviator Hellmuth Hirth. The venture initially focused on developing and producing light alloy pistons for aircraft engines, capitalizing on the post-World War I demand for advanced aviation components. With an initial workforce of fewer than 10 employees, the company laid the groundwork for its expertise in precision . In 1922, Hermann's brother, Ernst Mahle, a graduate engineer from the Technical University of Stuttgart, joined as the technical director, strengthening the firm's engineering capabilities. By 1924, the company underwent a significant transformation through a merger with Chemische Fabrik Griesheim-Elektron, pioneers in the Elektron magnesium alloy, leading to its renaming as Elektronmetall GmbH. This partnership shifted the business emphasis from aviation to automotive pistons, with light-alloy components increasingly applied in motorsports and series production vehicles; employee numbers had grown to around 50 by this period. Hermann Mahle was appointed commercial director in 1926, and Ernst took on the technical director role in 1927, guiding the firm's expansion. The Mahle brothers acquired equal shares in the company by 1932, becoming sole shareholders in 1933 amid the growing automotive sector. In 1938, they renamed it Mahle KG, underscoring their personal leadership and the firm's dedication to aluminum pistons for passenger cars, while introducing the enduring Mahle logo. The initial capital at founding stood at 100,000 Reichsmarks, reflecting modest beginnings that evolved into a robust operation. To safeguard the company's independence and align it with long-term societal goals, Hermann and Ernst Mahle transferred ownership to the non-profit Mahle Foundation in 1964. The foundation acquired 99.9% of the shares, ensuring strategic autonomy without private profit motives. By then, Mahle KG had expanded to 5,500 employees and generated annual sales of DM 200 million, solidifying its position as a key player in engine components.

Following , Mahle GmbH focused on rebuilding its operations amid the economic challenges in , resuming production of light-alloy pistons and expanding into new product lines during the 1950s. By 1948, the company introduced its first AUTOTHERMIK® pistons, designed for improved management in engines, marking a key step in recovery. In 1949, Mahle developed the first aluminum cylinder featuring a chrome-plated working surface under the CROMAL® , enhancing durability and performance for automotive applications. Series production of the AUTOTHERMATIK® piston began in 1955, incorporating advanced compositions to achieve better stability by compensating for differential expansion between the piston and cylinder materials through integrated insert strips. Mahle's key innovations in piston technology laid the foundation for its growth, with early breakthroughs including the development of Germany's first controlled-expansion in 1927. This utilized a special with embedded or iron strips to regulate , ensuring tight fits in cylinders across varying operating temperatures and reducing . In 1931, Mahle pioneered the world's first for diesel engines, where the ring carrier—a insert guiding the top rings—was integrated by the around it, allowing the material to shrink and lock securely during solidification for superior heat resistance and sealing. Later advancements included the three-piece oil control ring introduced in 1969, which featured two thin rails and an expander for low-friction oil scraping, minimizing oil consumption in high-speed engines. By 2003, Mahle launched the world's first all-plastic oil filter module, replacing metal housings with durable materials to reduce weight by up to 40% while maintaining filtration efficiency and enabling easier . International expansion accelerated in the mid-, with Mahle establishing its first production facility through MAHLE Cylinders Inc. in , in 1975, focusing on cylinder manufacturing to serve North American automakers. Entry into Asian markets began in the late , with the acquisition of Chongqing Changjiang Izumi Industries in in 2003, which bolstered local production and supported growing demand from regional manufacturers. These moves complemented earlier diversification into via the 1972 acquisition of a majority stake in Knecht Filterwerke in , enabling entry into air and oil products by the , and thermal management through the 1986 acquisitions of Técafiltres and Soparis in . By 1990, these efforts contributed to significant growth, with sales reaching DM 2 billion (approximately €1 billion) and the workforce expanding to 15,000 employees worldwide. A pivotal expansion occurred in 2013 when Mahle increased its stake in the Behr Group to 50.71%, acquiring majority control to integrate Behr's expertise in thermal systems such as radiators, condensers, and climate control modules. This acquisition, valued at several hundred million euros, allowed Mahle to consolidate its thermal management portfolio under a unified business unit, generating synergies through shared R&D facilities and supply chains that reduced development costs by optimizing component integration for engine cooling and cabin air systems. The integration was completed by late 2013, boosting Mahle's overall sales by €956.7 million from the Behr operations starting in October and positioning the company as a leader in holistic vehicle thermal solutions.
