The original Yugo
Is really one of these, a FIAT 127
Which was pretty much at the forefront of Euro car tech in the early 1970s = FWD, Monocoque (aka Unibody) construction, OHC engine and end-on gearbox. Compare that with the US compact car market which was the Chevette and Pinto with their RWD live axles - the FIAT/Yugo win.
Of course FIAT replaced the 127 with the UNO (good)
but Yugo continued with the older model.
They replaced it later with the SANA (AKA Florida)
But at about the same time the Yugoslavian civil war got in the way.
