Bus 712 was a Volvo B5RLEH diesel-powered parallel hybrid bus, with Bustech VSTH body which operated for ACTION between August 2017 and early November 2018.
When a trial of three plug-in electric buses planned for 2017 did not proceed, Transport Canberra sought tenders for “alternative energy” buses which could be evaluated for possible purchase. This vehicle, built to Transport NSW specifications in 2015, was offered for lease by Volvo Buses.
The B5RLEH is powered by a 4.76 litre 4-cylinder Euro V diesel engine and also a 120kW electric motor. According to reports, it used one quarter the volume of diesel over the same operating distance when compared with an unspecified control bus.
