Ok, it might not be as beautiful as the 507 roadster from the late 1950s, but then again the series is not called the “Most Beautiful Concepts We Forgot.” Billed as being a “masterpiece in mechatronic design,” the Z22 had just about the same footprint as a 3 Series (E46), but with the wheelbase of a 7 Series (E38). How was that possible? Just look at those tiny front and rear overhangs. Since the distance between the two axles was similar to BMW’s fullsize sedan, it goes without saying the amount of available room inside the cabin was comparable to the flagship. At the same time, the concept was about one third lighter than a 528i Touring (E39).
