Mahle Powertrain, a subsidiary of Stuttgart-based Mahle Group has acquired German transmission specialist ZG-Zahnraeder and Getriebe.

Mahle said the acquisition "adds significant extra transmission expertise as ZG will be part of the Mahle Powertrain family and the acquisition complements perfectly the company's dual strategy for optimising the internal combustion engine (ICE) and 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," said 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 [because] ZG has proven expertise in optimised 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."

ZG-Zahnraeder und Getriebe 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 programme inception to prototype testing, the company specialises in the development, optimisation and production of advanced gears with particular expertise in electric and hybrid drive concepts.
