Ashok Leyland unveiled HYBUS, India’s first plug-in compressed natural gas (CNG) hybrid bus, at Auto Expo 2010 (January 5-11, 2010 – New Delhi). The latest in green technology for urban mass transportation, HYBUS is more eco-friendly than a CNG-powered bus, thanks to integration of hybrid technology. Compared to a conventional bus powered by IC engine, HYBUS offers significant fuel saving of 20-30 per cent.

   The HYBUS combines conventional CNG engine with electric propulsion system. The engine is operated at an optimal efficiency to drive the generator for charging on-board battery. The Lithium-Ion battery that powers the electrical drive system provides the propulsion.

   The HYBUS intelligently selects the most efficient operating mode to ensure maximum fuel efficiency without compromising performance, comfort or passenger safety.

   R. Seshasayee, MD -Ashok Leyland, said they are happy to lead with green bus technologies once again, following CNG buses in 1997 and Hybrid Electric Vehicle in 2002. He added that for Indian cities where CNG is available, HYBUS is the greenest option with high performance, enhanced fuel efficiency and low greenhouse emissions, and noted that the commuter-friendly features getting inducted in the city buses are already helping in reducing traffic congestion and per capita reduction in fuel consumption and carbon footprint. He expressed that HYBUS heightens both the economic and ecological gains.
