Prague Public Transit Co. presents two new articulated hybrid buses

Prague, 12 January 2011 – The Prague Public Transit Co. (PPT) has expanded its fleet with the addition of two new SOR NBH 18 articulated hybrid urban buses. These buses were presented to the public for the first time today.

 

"The new SOR NBH 18 urban buses are equipped with an Allison parallel hybrid power plant that enables accumulation of braking energy that is then used during acceleration, theoretically resulting in fuel savings of up to 30%, and a corresponding reduction in the volume of emissions produced," stated Martin Dvořák, the general manager of the Prague Public Transit Co.

Low-floor SOR NBH 18 buses are intended for short-haul urban mass transit. They have a 151-passenger capacity (44 seated + 107 standing) and include space and anchor points for a wheelchair. They have three axles, five doors and are based on the SOR NB 18 urban bus chassis. Their maximum speed is 80 km/h.

Test operation of these new hybrid buses will be based out of the DPP Hostivař depot. During the first phase of testing, the Prague Public Transit Co. will deploy them on bus routes 136, 139, 250 and 271.

Operation of these two buses should confirm theoretical expectations of reduced fuel consumption when used within the City of Prague. Purchases of additional hybrid buses will be based on the results of test operation, with a framework contract with SOR Libchavy presuming the delivery of up to 20 of these buses.

"Prague City Council supports the development of hybrid urban mass transit vehicles, whose operation is easier on the environment," said Karel Březina, first deputy mayor and councillor for transport.
