Keywords: srm volvo opportunity charging opportunitycharging bus new routemaster newroutemaster wrightbus b5lhc omnibus indoor Looking towards the front of the lower deck of a Wrightbus opportunity charging (Volvo system) SRM bus. The large box on the left contains the batteries which make this an extended range hybrid which has its batteries topped-up at the route terminus. The SRM buses are part of the New Bus For London / New Routemaster family of buses but are only 10.6m long and feature a more traditional (for London) "twin door + single staircase" format. Another difference is that whilst the body style is NBFL / NRM the opportunity charging variant SRM uses the Volvo B5LHC chassis and a specially tweaked version of the Euro6 parallel style diesel hybrid propulsion that also allows travel in virtual electric mode.
