Even by the standards of the 1950s, with its visions of Jetsons-style technology, the Chrysler TV-8 was strange. Almost monstrous, like some mutated mushroom creature out of a 1980s post-apocalyptic nuclear horror flick.
Chrysler's design was essentially a giant pod-shaped turret mounted on a lightweight tank chassis, like a big head stuck on top a small body. The crew, weapons and power plant would have been housed in the turret, according to tank historian R.P. Hunnicut's authoritative "A History of the Main American Battle Tank Vol. 2".
