The goal was to explain the workings of Prius' Hybrid Synergy Drive in an informative, fun and engaging way. The challenge was how to make consumers understand now the system performs differently based on driving situations. The solution was to use 3-D rendering technology to create a virtual city filled with various driving situations (city driving, highway driving, etc.) for the Prius to drive through and showcase its technology.Understanding the main consumer benefits of the vehicle, we also integrated demonstrations on fuel economy and emissions, providing the user with not only the 'how it works,' but the 'what it does.'
