Leading market positions in our business segments

The MAHLE Group consists of four business units: Engine Systems and Components, Filtration and Engine Peripherals, Thermal Management, and Aftermarket. Added to this are the Mechatronics division and six profit centers, which serve specific market and customer segments.

With this structure, we offer our customers a high degree of flexibility as well as tailor-made applications and components and support them in the development of specific new products.

Engine Systems and Components business unit

Since our company’s early days, the development of piston systems and cylinder components has been a core competence at MAHLE. Because we understand the interaction of all engine components, we can deliver optimal solutions to our customers. Our products are used around the globe in two-wheeled vehicles, passenger cars, commercial vehicles, and large engines. And the range is continuously being expanded, so that emissions and fuel consumption in combustion engines can be further reduced in the future.

Filtration and Engine Peripherals business unit

MAHLE manufactures filters, pump systems, and oil coolers for engine and transmission applications—all of which are designed to increase the engine’s efficiency and service life and reduce emissions. We are thus contributing to clean air and preventing engine damage resulting from oil and fuel contamination. As a development partner and global market leader, MAHLE has partnered with its customers in recent years to develop modular systems for every major product group.

Thermal Management business unit

An increasing electrification of the powertrain calls for superior innovative capacity in thermal management—for batteries and the entire electric powertrain alike. MAHLE is a technological pioneer when it comes to the thermal management of batteries. Our solutions ensure constant temperature levels and an even distribution of temperature between battery cells. This produces long-lasting storage systems that deliver high performance.

Aftermarket business unit

This business unit supplies a broad portfolio of products and services in original equipment quality to the trade and automotive workshops worldwide. In addition to standard MAHLE spares, such as engine parts, filters, turbochargers, and mechatronics components, Aftermarket is increasingly offering products for thermal management, such as thermostats and air conditioning compressors. Vehicle diagnostics, exhaust gas analyzers, and service equipment for maintaining HVAC systems and automatic transmissions complete the product portfolio.

Mechatronics division

Mechatronic components are playing an increasingly crucial role in enhancing the efficiency of the powertrain and advancing e-mobility. With its electric drives, actuators and auxiliaries, and control and power electronics product groups, MAHLE already offers relevant solutions in this area today. These activities are founded on our expertise in the development and manufacture of electric motors, electronics, and mechatronic systems.
