Maserati Boomerang (1971)
Viewed from the outside, the Maserati Boomerang unveiled in 1971 isn’t strikingly unusual; wedge-shaped cars were trending during the early 1970s. What sets it apart from its peers is found inside. Positioned nearly vertically, the steering wheel rotates around an instrument cluster with seven gauges, various switches and an array of warning lights. The concept is fully functional, meaning people drove it and realized this wasn’t the most ergonomic way to present information.
