Has this idea any future? We haven´t heard about it any more.
The original concept eventually morphed into the BMW i8 and i8 Spyder. Which by all accounts is expected to be green lighted later this week for a late 2015 launch.
The proposal with TOYOTA is scheduled to come as both Roadster and Coupe, I would like the think that some of the ideas from the initial strategy conforms to that project.
