The diminutive Zastava was endearing enough to earn the nick name Nicia, which means Little Fiat in Serbian. As was its Fiat 500 cousin to the west, the compact Zastava was endlessly modified and by way of engine swaps and other creative mechanical mayhem. The final version of the car packed a very close to Fiat 850 engine which belted out 39 horsepower. A glorious day Comrade! We ended up with the slightly more powerful Yugo here in the states, also known as the 2CV of the Americas.
