Outsource every part of your powertrain operations, from concept to industrialization to manufacturing

To retain market share globally, OEMs will have to innovate both with conventional powertrains and with e-Drives for many years to come. Significant investments are required in ICE design and production to stay ahead of the competition.

Aurobay offers a seamless end-to-end powertrain service for combustion engines, hybrid powertrains and range extenders – through design, industrialization and manufacturing.

Our world-class engineers push the boundaries of powertrain innovation, driving down emissions, driving up performance and minimizing costs. Once the design is improved, we will industrialize it for efficient production in our advanced facilities in Skövde and Zhangjiakou. This includes optimizing the flow of the production line, smooth inbound and outbound logistics, and ensuring a low material scrap rate through careful production design.

We will then deliver your engines ready for installation at your vehicle plant. All the while, keeping tight control of quality through extensive testing and verification, including digitally-enabled traceability during production.

By partnering with Aurobay as your one-stop-shop for complete powertrain services, you can be confident your requirements will be delivered cost-effectively, to a high standard through every stage of the powertrain journey.
