Many advantages speak in their favour. Most important, the roof modules will enable car manufacturers to significantly reduce their logistics expenditure in future. Instead of installing a multitude of single parts in vehicles on the production line, the roof modules delivered in the desired time and sequence will only need to be integrated into the standardised vehicle shells. This permits a reduction in the necessary body versions and ensures increased flexibility, for example in reacting to customer requests. New features, e.g. light, aerial or head airbag, can be integrated with greater speed into a vehicle, because no changes are required either in the production sequence or in the  vehicle interfaces.
