First hybrid double decker bus hits the road in London

There are certain iconic images that when seen by most people immediately bring to mind a certain place. The Eiffel Tower calls up Paris. A pyramid makes people think of Egypt. Seeing either Big Ben or a red double-decker bus almost invariably makes people think of London, England. The classic London bus is now moving into the new century with the entry into service of the first hybrid variant. The new bus is a series hybrid with a 1.9L diesel engine. The standard version of the bus uses a 7.0L engine. The diesel is used drive a generator to charge the 660V lithium ion battery pack which feeds a pair of 85kW electric motors. If you happen to be in London you can catch the first hybrid bus on Route 141.
