Hybrid transmissions have been the subject of many investigations, initially sponsored by the Environmental Protection Agency in the us and more recently supported by energy research and development councils in various countries of the world. Since the petrol internal combustion engine operates in a very inefficient mode, commonly less than 10 per cent, with a maximum possible efficiency in the order of 30 per cent, there is considerable room for improvement in decreasing the fuel consumption of present day automobiles. The paper describes a novel method of utilising two types of storage, namely batteries and a flywheel and incorporating them with a power sharing epi-cyclic gear box coupled to a relatively small internal combustion engine which provides the long range capabilities of the vehicle. The combination of the two storage devices ensures adequate acceleration performance equivalent to the present 4 litre, 1500 kg car (a). (TRRL)
