Some info on the kind of plug-in hybrid I want i.e. large electric motor and small I/C. I just hope some manufacturer builds something like this in the future. Given a dedicated design instead of piecing together existing components I think it could be 30 to 40% more efficient. http://www.team-fate.net/techpapers/The%20...c%20Vehicle.pdf Plus another interesting read http://www.epriweb.com/public/000000000001000349.pdf
