This inaugural service comes after the Mayor of London, Ken Livingstone, recently announced plans for an increased hybrid bus fleet for the capital.
Built by Wrightbus, the double-decker is a series hybrid with a 660-volt lithium-ion battery pack powering two 85kW electric motors. A 1.9-liter Euro-4 diesel engine is the genset. By contrast, a conventional double-deck bus uses a 7-liter engine. The hybrid bus is expected to cut emissions by up to 40%.
