Anyone heard of the Fiat ESV ?

[Minijohn]

Only just stumbled across this monstrosity - wonder why it never reached production? 

In total, Fiat built three cars for the safety contest. The first was the ESV 1500, a compact 680-kilogram rear-wheel-drive sedan built using components from the Fiat 500 and Fiat 126. 13 prototypes (mostly in red and yellow) were assembled and shown at conferences in Washington and Kyoto. The black parts are polyurethane linings, which avoided damage during accidents at city speeds.
