E.E: What can you tell us about market trends?

There is a huge swift towards (Battery) Electrical Vehicles. For steering and suspension parts this is not a threat, but requires engineered solutions to withstand the higher weight of the cars (due to the heavy battery pack) and the higher torque to ensure maximum strength and safety.

Another trend is the rise of Chinese Electrical Vehicle brands (e.g. BYD). Here again, no threat for Sidem as also those brands are monitored.
