9. Chrysler Airflow

The Chrysler Airflow, introduced in the 1930s, was a trailblazer in aerodynamic engineering. Its streamlined shape and innovative unibody construction improved both fuel efficiency and passenger comfort—features that would become industry standards decades later.
Unfortunately, the Airflow’s radical looks confused traditional buyers, and its advanced technology was ahead of market acceptance. Sales were disappointing, prompting Chrysler to revert to more conventional models.
Despite its commercial struggles, the Airflow’s influence is visible in the evolution of automotive design. Read more about its legacy at Smithsonian Magazine.
