Altair Engineering has unveiled the LCO-140H (Low-Cost of Ownership-1st 40-foot Hybrid), said to be the world’s first series hydraulic hybrid transit bus. This was developed under the BUSolutions program in partnership with Automation Alley to revitalise bus transport in America.

According to the company, the fuel economy results are 110% better than conventional diesel buses and 30% better than diesel-electric hybrid buses. It is also said to have achieved a fuel economy of 6.9mpg when tested using the downtown ‘stop-and-go’ duty cycles and test protocol established by the FTA for transit bus certification testing.
