Here's the BMW prototype roadster that caused a split among those who thought was the new Z9 (Z8 replacement) and others who swore it was the Z4. Those in the latter camp were sold by its size and scale, though some massive body panels caused those in the former camp to think the proto-Z was larger than it is. All we know is a new facial treatment keeps the kidney grille, though alterations appear to be focused around the lamp areas. The mecha-shark body style, however, looks largely the same.[World Car Fans]
