Have you ever wondered why Toyota and Honda brought hybrids to global markets before anyone else but have been behind Nissan, General Motors, and BMW in plug-in electric vehicles? According to a few auto industry insiders, Toyota and Honda have been more convinced about hydrogen fuel cell vehicles than plug-in electric vehicles. Honda has been testing, in a very limited way, its FCX Clarity, on lease deals in California since 2008. Toyota has said once again that it will be bringing a fuel cell car to its dealership network in 2015, said Justin Ward, advanced powertrain program manager at the Toyota Technical Center in Ann Arbor, Mich. Initially it will go in sale in California, which plans to have 68 hydrogen fueling stations up by the end of 2015. Ford, GM, Chrysler, and Volkswagen plan to roll out their own fuel cell cars, but are not saying when.
