Our core competencies in engineering are power-train technologies and lightweight engineering. Our service portfolio ranges from efficiency technologies and the development of combustion engine systems to electric drive systems. In the area of lightweight engineering, our focus is to compensate for the additional weight of comfort and safety systems and added drive components. GreenIng`s cooperation with university institutions results in unique synergies from basic research and practical serial development. We work under contract (concept examinations, design/construction), do consulting (assessment of technologies, training) and basic research. In our technology lab, we can build and validate vehicle prototypes. In addition, we use our e-test vehicle to test electric drive components. This "open source" drive assembly carrier is built on an existing vehicle platform and equipped with the latest electric drive technology. The technology carrier is versatile and can be used for validating new systems and components for electric vehi-cles. It can also be used for manufacturer-inde-pendent training purposes.
