To "push the limits / boundaries as further as possible" is the work of a Concept Car.
To "work on refining & evolving the solutions / design theme" is what a designer does for the car that will enter the market.
Bangle and Co have turned some of their cars into Concept Cars and released them completely unrefined on the market. It's a completely wrong move in my eyes. That is why the Beemers only begin to look how they always should have looked...
That is at least how I see things!!
