> still in the concept phase

Multiple generations of prototypes and hundreds of thousands of miles driven is well past the concept phase.

This just comes down to your definition of concept. I consider a prototype as a concept car that exists to show the feasibility of the concept but it has a ways to go before it is ready for production.

[seanflyon]

That makes sense. I would consider a concept to be an idea or a plan, not a working product.
