Future meets the past—the MAHLE story from the beginning

Ernst Mahle

The idea on which MAHLE was founded was new and different, and it went one step further.

The success story begins in 1920 when pistons made of heavy gray cast iron were being used in internal combustion engines for automobiles. The Mahle brothers countered this trend by producing light-alloy pistons at their small, newly established company—but the technology is still finicky, and problems come up frequently. To keep dirt and dust out of the engine, they eventually developed air and oil filters as well. Their perseverance paid off: the light-alloy pistons began to take over the market.

Nowadays, half of all automobiles produced worldwide contain MAHLE products. MAHLE has developed from a small test workshop to a technologically leading, globally active systems supplier to the automotive industry.

History1920—1932

alt

Renewal. Development. Breakthrough.

From a small test workshop to a technologically leading industrial company: the central issue at the time is whether the light-alloy piston favored by Ernst Mahle can replace the gray cast iron piston. New alloys and the invention of the ring carrier piston by Ernst Mahle finally provide the breakthrough.

History1933—1945

alt

Dictatorship. Armament. War.

National socialism and World War II also leave a deep mark on the development of EC as a company: aircraft, cars, and commercial vehicles are soon being built primarily for military purposes. And this is how EC—known as MAHLE KG from 1938—becomes a key supplier to the armament industry. Forced laborers also work for the company from 1940 onward. By 1944, the number of employees—including foreign and forced laborers—increases to more than 6,000.

History1946—1970

alt

Destruction. Reconstruction.

Sixty percent of MAHLE KG’s value and assets were lost in World War II. The management of the company is handed over to trustees until 1948. Following the initial hard years after the war, the company has to survive by manufacturing other products, but soon benefits from the general economic boom.
