Plug-In Natural Gas Hybrid Vehicles: A Game Changer [View article]
PHEV-NGVs would be an excellent idea. However, I see two problems.
1) You would be asking current auto manufacturers to take risks on two new technologies. Even something as simple as a NGV is only being made available by Honda. They are resistant to even making cars use that only one of these technologies: PHEV or NGV
2) Another problem is weight: 400 lbs in lithium batteries and the NG tanks weigh at least 200 lbs each and you would probably want to have two tanks for extended range. This extra 800 lbs minimum would certainly make the car less efficient than a standard ICE (Internal Combustion Engine) car.
