Thomas Built Buses announced on 23 October that it will further expand its alternative-fuelled offerings with the addition of a CNG Saf-T-Liner C2 school bus. Thomas Built plans to fit this bus with a Cummins Westport ISB6.7 G 6.7-litre natural gas engine currently in development and expected to be available in 2015. The ISB6.7 G engine, based on Cummins’ ISB6.7 diesel, will use Cummins Westport’s spark-ignited, stoichiometric-cooled exhaust gas recirculation (SEGR) technology.
Thomas Built’s current line-up also includes the Saf-T-Liner C2e diesel-electric hybrid, propane-fuelled Minotour and Saf-T-Liner HDX CNG models. A propane-fuelled version of the Saf-T-Liner C2 bus is expected to be available in 2013.
Thomas Built Buses launched its Type D CNG-fuelled rear-engine Saf-T-Liner HDX school bus in 1992, since when the company has put more than 1,300 HDX CNG buses on the road and says it has seen demand increase in the last five years.
