TOYOTA and French power company Electricite de France (EDF) have teamed up to explore plug-in hybrid technology. Under an agreement, a small number of plug-in hybrids will be integrated into EDF's fleet and will be tested on public roads in France under everyday driving conditions.

The vehicles use Toyota's hybrid technology but can be further charged by plugging the car into an electric socket. EDF and Toyota have also developed a charging and invoicing system, equipped in each of the test vehicles.
