The BUSolutions demonstrator LCO-140H (Low Cost of Ownership–1^st 40-foot Hybrid) series hydraulic hybrid transit bus yields fuel economy of 6.9 mpg (34 l/100km) on the industry-standard ADB duty cycle—110% better than conventional diesel buses on the road today and 30% better than the best-in-class electric hybrid buses available today, according to the final report on the project published by the US Federal Transit Administration (FTA).

More importantly, according to the report written by a team from Altair ProductDesign, which led the project, such a bus will cost more than 20% less than a conventional diesel bus to own and operate over its life and more than 30% less than an electric hybrid.
