At the 1976 Geneva Motor Show, Alfa Romeo revealed the final iteration of its series of concept cars based on the race-inspired Tipo 33 Stradale chassis and drivetrain. This final concept, named “Navajo”, was penned by Nuccio Bertone and was perhaps the wildest and most “futuristic” take on the Tipo 33 concept cars. Looking like something out of the “Star Wars” movie, which was wildly popular that year, the Navajo featured a rectilinear, wedged shape body with active spoilers.
