Hinduja Group flagship Ashok Leyland today unveiled HYBUS, India’s first plug-in CNG hybrid bus, at its stall at Auto Expo 2010. 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%.

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. HYBUS has a host of commuter-friendly features including ultra low entry at 390mm with kneeling option, noise-free rear engine, front and rear air suspensions and retractable ramp for wheel-chair entry.

HYBUS also incorporates some innovative pedestrian safety concepts: sound and light alerts while the bus moves, a camera-assisted reversing aid for the driver and night time highlighters near the tail lights. The bus front has a novel design to absorb impact on collision, which drastically reduces severity of injury.

“We are happy to lead with green bus technologies once again, following CNG buses in 1997 and Hybrid Electric Vehicle in 2002”, said R Seshasayee, MD-Ashok Leyland. “For Indian cities where CNG is available, HYBUS is the greenest option with high performance, enhanced fuel efficiency and low greenhouse emissions”, he added 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. “HYBUS heightens both the economic and ecological gains”, he said.
