This project gave the drive systems producer Voith and bus manufacturer Solaris the opportunity to optimise bus hybrid systems in conditions other than just on a test bench: the preproduction vehicle was optimised and tested in real operation on site in the presence of future operator BOGESTRA.

The participating companies were able to acquire important expertise in developing and using the pre-production vehicle. The insights gained have already been successfully implemented at Voith and Solaris in the course of full production of 18 further buses of the same type. All of the participants now have the necessary experience in the areas of repairs, servicing and especially in respect to working with high-voltage equipment. During the long-term use of the bus in scheduled operation, BOGESTRA, as the operator of the pre-production vehicle, was able to test out the handling of such vehicles, to satisfy itself about their possible uses and to examine the potential for fuel savings, as well as to train safety personnel.
