'Serial Hybrid' uses electric motors "exclusively" to drive the vehicle and the combustion engine is used to drive a generator to power the electric motors and re-charge batteries. Diesel-Electric trains do this very well. The "combustion engine" could be a small power plant that uses fuel cell tech, or Natural Gas, or gasoline then engine size does not have to large. The electric motor has a lot of torque so it can handle any load or any application. Siemens has been around and produced electric motors since the late 1800s. Ford and Siemens could combine: Ford engines and vehicles with Siemens electric motors, controllers and other electronics to produce a planet loving vehicle product. I have read several ideas from others that suggest the same thing. The technology is here now. I realize that no other car maker is working on this, but, Ford should do this. By using a small engine to turn a generator, an EVs range would be limitless. The torque produced by the electric motors in a 'serial hybrid' configuration could power commercial trucks.
