For the third time, the Prius-III PHEV-12

Based on the third-generation Prius, the PHV Concept expands Toyota?s Hybrid Synergy Drive technology, utilizing first generation Li-Ion battery technology and enabling electric operation at higher speeds and longer distances than conventional hybrids. When fully charged, the vehicle is targeted to achieve an electric-only range of approximately 12.5 miles and will be capable of achieving at least 62 mph highway speeds in electric-only mode. For longer distances, the PHEV concept reverts to ?hybrid mode? and operates like a regular Prius. This ability to utilize all-electric power for short trips or hybrid power for longer drives alleviates the issue of limited cruising range encountered with pure electric vehicles.
