Mahle acquires the German transmission design specialist

Mahle’s acquisition of the German transmission specialist ZG-Zahnräder und Getriebe GmbH adds extra transmission expertise to Mahle Powertrain.

ZG-Zahnräder und Getriebe GmbH was founded as a spin-off from the Technical University of Munich in 2008 and today works closely with several major vehicle manufacturers and Tier 1 suppliers. From program inception to prototype testing, the company has established a core competence in the development, optimisation and production of advanced gears with particular expertise in electric- and hybrid-drive concepts.

ZG-Zahnräder will become part of the Mahle Powertrain family, and the acquisition complements the company’s dual strategy for optimising the internal combustion engine (ICE) while focusing on new developments in alternative drive technologies.

“As drivetrains are increasingly integrated in pursuit of reduced emissions, efficiency gains come from increasingly focused refinements,” says Simon Reader, Mahle Powertrain engineering director. “Gears can be overlooked, whether in the ICE, transmission or an electric driveline. Today’s high-torque hybrid powertrains demand exceptional gear refinement and durability, but there is a constant need to reduce component size and weight.

“This is where the ZG acquisition fits in. The ZG team has proven expertise in optimized gear design and transmission layouts. These can facilitate marked improvements in NVH, friction performance, packaging and weight reduction, leading to improved efficiency, especially for electric drives. Every aspect of our work, from full powertrains to electric drivelines, can be improved by good gear and transmission design, which is why ZG’s acquisition is an important development for us.”

The deal is the latest investment in future powertrain development facilities and the expertise of Mahle Powertrain, the propulsion systems development specialist, which also has expanded its GBP 8.3 million Real Driving Emissions Center to help the automotive industry meet stringent future efficiency targets.
