I'm sure that everyone realizes that the production ELR will look somewhat like the concept, except for changes made for the ELR to meet federal safety standards.
My guess is that the windshield will not be as large as the concept and that some type of "B" pillar will be added to meet rollover standards. Swingup doors (Scissor doors?) would be great, but I don't know enough about the difference in structure or weight that might mean they wouldn't be considered.
Clearly, the interior must be outstanding. It must shout, buy me and you will be coddled in luxury and the latest in electronic toys.
It should be interesting!
My biggest problem with something changes is the side mirrors. They will have to facilitate actual mirrors and unless done right (camaro mirrors maybe?) they could look gaudy.
