Italdesign – particularly Giorgetto Giugiaro – designed a handful of Lancia products throughout the '70s. But arguably the firm’s greatest achievement was the Delta hatchback. Following its introduction in 1979, it was voted European Car of the Year in 1980, and went on to spawn the hot rally versions, the HF Integrale and the HF Integrale Evoluzione, that we know and love today.
