If you want to know what types of electric cars are available and how many are out there, there is a website that can help. The plug in vehicle tracker has a list of the highway-capable electric vehicles under development or production broken down by manufacturer. The table has a column showing the "Target Intro" and "Progress" of each make. Most have a label saying they are only a prototype or that there is no planned mass production. However, one thing of note is that those that do have years of planned introduction almost always are being introduced into China and then Europe and then the United States. One more sign that in matters of energy and transport the United States is a backwards player.
