Future meets the past—the MAHLE story from the beginning

Dr. 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 components. MAHLE has developed from a small test workshop to a technologically leading, globally active Group.

Renewal. Development. Breakthrough

From a small test workshop to a leader in technology and an industrial enterprise: 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.

War. Armament. Destruction

The darkest chapter in German history—national socialism and World War II—also leaves a deep mark on the development of EC as a company: with aircraft, cars, and commercial vehicles being built primarily for military purposes, EC—known as MAHLE KG from 1938—becomes a supplier to the armament industry because of its product range.
