Early versions ofthe vehicle used a Nickel-metal hydride battery. Nitz says “But now we’re using lithium-ion batteries. We’ve done extensive battery thermal management work in the lab and on the road, and plug-in charge integration is fully operational and undergoing refinement.” There is still more research and development that needs to take place before the plug-in Vue is at a showroom near you. Based on Nitz’s announcement it would appear that the Saturn team are on the right path to getting the vehicle into your garage within the next few years.
