Tata Motors puts first hybrid bus on Delhi roads

(September 27, 2010) Tata Motors this month presented to the Delhi Transport Corporation (DTC) the first of four CNG-Electric Hybrid Low-floor Starbuses. This is the first time in India that hybrid buses will be used for public transportation.

Meant for intra-city transportation, the Hybrid Tata Starbus is powered with a parallel hybrid engine comprising an internal combustion CNG engine and an electric motor using regenerative energy storage system. Parallel hybrid technology uses power generation simultaneously through both the CNG engine and the electric motor to drive the vehicle. The system reutilises lost braking energy to recharge the battery.

The Tata Hybrid Starbus offers substantial improvement in fuel economy compared to a conventional bus. As a result, the usage of this technology leads to lower emissions, thereby contributing to cleaner air and a greener, more environment-friendly commercial passenger transportation application.

The low-floor (15.7 inches in height) air-conditioned bus can seat 32 passengers, and can also accommodate wheel chairs. Pneumatically operated in-swing and out-swing flat doors and kneeling facility allow easy entry and exit, reducing halt time and trip lengths.

Full air suspension and telescopic double-acting shock absorbers provide excellent ride quality, while an energy-efficient HVAC system enhances comfort. With high starting acceleration, and a maximum speed of 43 miles per hour, the Hybrid Starbus is an innovative solution for fast and comfortable intra-city passenger movement in an environment-friendly manner, Tata says.

The four hybrid buses will run in the city of Delhi during the Commonwealth Games period.
