Based on the other day's spy shot of the mysterious BMW being rolled into storage, Jon Sibal made a rendering of the future BMW Concept Vision Z or Z6 set to be revealed at the Frankfurt Motor Show.

The Z Vision Concept is a combination between the 3 Series Coupe and the CS Concept. This concept will be the first one to use the new upturned grille, and will be followed by the next generation BMW 1er Coupe and by the BMW Z2 Roadster and Coupe.

If only BMW hadn't denied this one.
