One of Madrid’s city transport companies have asked Tata Hispano Motors Carrocera SA (Tata’s wholly owned subsidiary in Spain) to provide them with 10 of their CNG Series Hybrid buses. These low floor CNG buses are powered by latest environmentally friendly hybrid technology and have some really advanced convenience features as well. The buses will be delivered to the city transport company in 2012.
Meant for urban transportation, the Tata Hispano CNG Hybrid is powered with a series hybrid system. For a series hybrid vehicle, the engine is not connected to the driveline. Instead it just runs a generator which charges the battery pack at a steady power. The battery pack provides electrical energy to the motor which in turn generates tractive power. Besides, the engine operates on a constant speed, constant load mode, maximising engine efficiency irrespective of large variation in vehicle speed and frequent stops and starts. The vehicle chassis is capable of being integrated with pure electric mode, CNG micro turbine and hydrogen fuel cell in the future.
The low-floor bus (floor height: 350 mm) is equipped with heater, air-conditioner, wheel chair, baby seat, space for luggage, security cameras, WIFI, electrical ramp, ticketing machine, reverse camera, electronic display board, electrically operated in-swing and out-swing doors and kneeling facility allowing easy entry and exit, reducing halt time and trip lengths. Electronically controlled air suspension (ECAS) and electronic braking provide excellent ride quality, handling and passenger comfort. With high starting & smooth acceleration, and a maximum speed of 70 km per hour.
Nice to see Tata buses plying on Madrid streets – way to go, Tata!
