I have successfully converted a ordinary car(a VW) into a plugin hybrid electric vehicle with 50 miles drive range and 50 miles/h speed using two 96V 80AH lithium battery installed in the car trunk. The conversion procedure is very simple and does not change the original car's gas power system at all. You can drive your car using gas as usual but you can always switch to electric drive any time you want. I already have patent protection and would like partners to join me in this project to make every car driving in city emission free.
