Components

We develop and optimize all components from the hybrid system

All components in the hybrid powertrain must be coordinated to optimize performance, ride comfort and fuel economy for the drive concept. Our unparalleled expertise in the entire vehicle puts us in a position to develop all components for complex hybrid systems to the level of mass production. We meet the demands placed on functionality and efficiency by following a start-to-finish process for developing components, functional assemblies and complete hybrid systems. Our development teams selectively use design and simulation tools, some of which have been engineered in house, state-of-the-art CAD and PDM systems as well as a wide range of measuring and testing equipment.
