The 1958 Sir Vival was Walter C. Jerome’s eccentric concept car, designed in Massachusetts to be the world’s safest vehicle. Built upon a modified 1948 Hudson, its revolutionary segmented design split the car into two sections connected by an articulated joint. The front half was meant to absorb head-on collisions, safeguarding the passenger cab. It featured a raised driver’s turret for 360-degree visibility, plus early innovations like seat belts and roll bars. Despite advanced features and high-profile showings, only one prototype was ever built.
