Wrightbus is launching the new generation StreetDeck Ultroliner, featuring the Cummins B6.7 diesel engine and Voith transmission, maintaining ultra-low emission standards for diesel buses. The Cummins-powered Ultroliner is accredited as an Ultra-Low Emission Bus (ULEB), continuing the environmentally friendly legacy of Wrightbus. The first five buses will be supplied to Bus Vannin, the Isle of Man's government-owned bus service. These buses offer two horsepower options to ensure efficient and smooth operations. While currently diesel-powered, the buses are designed with the potential to integrate hydrogen technology in the future, aligning with Cummins' advancements in this area. Wrightbus emphasizes a responsible transition to cleaner technologies, including battery electric and hydrogen fuel cells, to facilitate decarbonization while maintaining operational viability. The company aims to enable a potential mid-life repower of these diesel buses to zero-emission vehicles through its NewPower business. Bus Vannin's Director acknowledges the buses as a step forward in internal combustion engine technology, remaining mindful of climate commitments and potential future hydrogen options in line with electrification trends.
