Hyundai Motor is currently developing their very own plug-in hybrid vehicle with a 2013 launch date being targeted, intending to bring this eco-friendly four-wheeler to both folks at home as well as others living abroad. So far, Hyundai has paraded a prototype Sonata plug-in hybrid from its plant, where said prototype took a good three years and more to build, only to be ready to face some real life world testing this time around. Basically, full electric vehicles still have some distance to go before they can be commercialized for the masses simply because of the lack of long distance support as well as scarce charging facilities. This is why Hyundai went ahead with their plug-in hybrid electric vehicle first before taking the next big step forward.
