ZFs work better with the Cummins ISBe compared to Voiths though.

Got to bear in mind that whilst Stagecoach have a good partnership with Voith, then unless Scania clean up their act and tailor the needs of the new N250UD to Stagecoach, then a ZF Gearbox coupled with a Cummins ISBe engine would be better suited to the interurban type of work that a Scania would traditionally be used for and therefore, Voith wouldn't lose out on any trade as the ADL E400s with the Scania chassis / engine already have ZF Ecomat (Ecolife MMC onwards) gearboxes fitted.

Voith gearboxes are more suited to being s**t of the mark around towns and cities whereas the ZF Gearbox is desgined to give a more smooth and continuous power delivery.
