3. Chrysler TurboFlite
Introduced in 1961, the Chrysler TurboFlite was a radical concept car that showcased a third-generation turbine engine. Designed by Virgil Exner and built by Ghia of Italy, it featured a retractable glass canopy that lifted in sync with the doors, and a prominent rear spoiler. Despite its innovative design, the turbine engine proved impractical for consumer vehicles, making the TurboFlite a glimpse into an alternate automotive future. (motorcities.org)
