One thing that really impressed me about the Model S is the overall efficiency. Yes, the model S is a very fast large luxury car with a long range but does not use up much more energy than a Nissan Leaf. I'm also impressed how much progress Tesla has made in the last four years. The Model S is much more efficient per pound than the Roadster.
I created this comparison table.
I have to admit, I didn't even look at the Ford Focus Electric or the Mitsubishi Electric. These low end range vehicles have a place but I'm not particularly interested in them myself.
I have seen very little discussion on this topic. I think going forward overall efficiency is relevant for both costs of electricity and the way electricity is produced. I have more than enough solar panels to support both my home usage and one electric car.
I don't think Tesla can keep pace with something like Moore's law as there is not a correlation. I'm wondering where future improvements in efficiency can come from.
