Can we simmer down a little bit? I have both cars and enjoy them. They both have their purposes, and I happily plug both in at night. In the Volt, I'm still on the tank of gasoline from the dealership since March. It's used for a second car and squeezing miles out of the battery is kind of a fun game.
Enjoy the cars, enjoy the cost savings, enjoy the technology, etc. We're all of similar mindset.
And for the record, the Volt is an EV with a range extender. The main difference between the Volt and the i3REx is the Volt's generator (electric side) is used for driving the wheels when it's not generating. There is never a link between the ICE and the wheels. The REx in the i3 has a dedicated generator (lawn mower!)
This has been covered a thousand times but there can be a mechanical linkage between the motor and wheels (accelerating up a mountain for example) I thought.
