The curves on the 1941 Chrysler Thunderbolt were inspired by streamliner trains. The car was among the first to have power windows -- Chrysler used hydraulic motors to move them. The fully retractable hardtop and button-operated pop-open headlights were also seminal design features that showed up in cars decades later. It was one of the last Art Deco designs before concepts leaned towards futuristic aesthetics.
