4.Alfa Romeo P33 Carabo
When it comes to supercar designs, the Carabo from Alfa Romeo is considered one of the best. This was another creation from Marcello Gandini of Bertone, and the name Carabo means beetle. This supercar was based on the wedge design, and a number of future supercars introduced in the market took some styling cues from the Alfa Romeo Carabo. The Carabo was never planned for mass production, but a prototype was based on the Alfa Romeo 33 Stradale, with a projected top speed of 250 km/h.
