The Volvo hybrid bus that was unveiled at the Delhi Auto Expo, would be launched on Bangalore roads soon, said Karnataka Transport Minister Mr. R Ashoka.
The 105-seater single bus would have a two-month trial run in the city, expected to be from this month itself. As per a preliminary report, it cuts diesel fuel costs by 30 per cent, while emissions are significantly less.
According to officials, the Volvo 7700 hybrid has a diesel engine and an electric motor, which can be used either independently or jointly. The battery that drives the motor is charged through re-generative braking. The engine shuts off when the vehicle is stationary and does not start again till the bus reaches 15-20 kmph, further saving fuel.
