This paper examines the energy cost saving by adopting plug-in hybrid electric vehicles in Toyota City, Japan. Two types of sample data are used in this study, the probe data of plug-in hybrid electric vehicles and person trip survey data. The probe data collected in the social experiment of Smart City in Toyota City are used to propose estimation formulations for electricity and gasoline consumption rates for plug-in hybrid electric vehicles. The person trip survey data collected in 2011 are used to understand the travel distance of ordinary motor cars in Toyota City. The major findings suggest that 1) approximate 81% of vehicles can save energy cost by 85% in workday, and 70% of vehicles can save 85% of energy cost in holiday. 2) 12% of vehicles can save energy amount more than 500 Yen in workday, and 22% of vehicles can save the same amount in holiday.
