Abstract Automation Alley, Altair, and the Federal Transit Administration (FTA), in a public-private partnership, teamed up to advance a new transit bus initiative that would improve Americas local and regional transit systems while requiring no infrastructure upgrades to op-erate. The goal was to develop a significantly lighter-weight, heavy-duty bus design that yields superior fuel efficiency to conventional buses at a lower lifecycle cost. The four main areas of focus for reducing the lifecycle cost of the new bus were purchase price, fuel economy, scheduled maintenance, and unscheduled maintenance. The results yielded the Altair ProductDesign LCO-140H hydraulic hybrid bus. A physical technology demonstration vehicle that is projected to have a 20 percent lower purchase price than most electric hybrids and saves over 30 percent in total lifecycle costs. The LCO-140H is projected to even save 20 percent in lifecycle costs over a basic non-hybrid diesel bus. Fuel economy test results showed a 110 percent improvement in fuel economy as compared to the aver-age non-hybrid diesel bus, and over a 30 percent better fuel economy than the best-in-class hybrid electric bus results found in the Altoona database. The net result is that this design enables a transit authority to reduce their reliance on oil and save money while doing it.
