http://www.electricdrive.org/ All the major car manufacturers are developing the hybrid now. >From the feature: Ford, Porsche, BMW, DaimlerChrysler, GM. All of them perhaps have big research program on fuel cell, 42V vehicle power "bus" and some high speed protocol to replace CAN or similar but all that is future. GE and Siemens and some others also have big interests in this kind of things. I hear that GE's NY research center (Schenectady, near to Albany, the state capital) is doing some very advanced research on this field.
