The Maserati Boomerang!
Giorgetto Giugiaro’s wedge-shaped concept shocked when it first arrived at the ’71 Turin show, but it influenced the angular look of supercars for two decades to come, and particularly Giugiaro’s own Lotus Esprit. Only one running Boomerang was made; it used a Bora V8 and still exists. The angle of the windscreen was 15 degrees, which was the steepest rake you could achieve and stilll see out of. Hats off once again to the Italians.
