The acceptability of the hybrid electric vehicle (HEV) technology in Philippine tricycles will be defined by its economic viability. This study investigated the optimum HEV component and control variable combination that will provide the most incremental life cycle cost benefits relative to the current conventional tricycle power train. Simulations were implemented using an instantaneous vehicle model specifically developed for Philippine tricycles and based on local drive cycles. Its viability was evaluated vis-a-vis projected technology developments and component price reductions. Results indicated that the 60 cc ICE, 8.66 kWpeak and 0.47 kWh battery configuration will provide the best fuel economy and highest financial feasibility while the 70 cc and 80 cc systems may also be adopted should lower capital cost is desired. Viability is strongly dependent on future fuel oil prices and is not expected before 2020.
