A gas turbine/battery hybrid system adopted as the power plant to propell a passenger car has been in development to seek a better fuel economy to drive. The gas turbine engine is a single-shaft type having 86000 rpm which is coupled directly with a generator to yield electricity. The power is used either to propell wheels and/or to charge battery depending upon the operating conditions of the system. The aim of this study is to attain a better fuel economy by operating the engine only around its rating point regardless to the driving conditions of the vehicle. The experimental vehicle has been studied to evaluate the potential of this unique system. Based on the detailed study of the components of the system and the road-load testings of the vehicle, the potential is seen for the system to be superior than a conventional vehicle. This paper will descrive the experimental results of the vehicle performances by this stage suggesting a good potential of the system when developed fully.
