A lot of buzz in the Dealership lately revolves around the now in field testing Prius Plug-In Hybrid. Like the conventional Toyota Prius the new plug-in version uses a 1.8 litre Synergy Drive Hybrid system but instead of the nickle-hydride battery, a new lithium-ion batter is used along with a "plug in" feature to top up the battery's charge when parked. It's not clear when exactly the new lithium-ion batteries will make there way into the mainstream Prius, Camry and Highlander Hybrid line. But once lithium-ion technology can safely replace nickle-hydride batteries currently used, the hybrid vehicle will have a whole lot more (pardon the pun) charge in it!
