Although it looks like a Bertone concept, it is not! In fact this is the 1969 Ghia Lancia HF Competizione concept. I don’t have a ton of information about the actual car; however I do know that it was based on the standard Fulvia HF platform and was FWD with the famous 1600 V4 engine from the Fulvia HF. However, a major difference was that the Ghia concept was even lighter than the standard Fulvia—-which made it even faster and (supposedly) with better handling. The idea was to possibly use this as a basis for a racing car that would have possibly be entered into Le Mans-type race events; alas this was not meant to be.
It was shown at the 1969 Geneva Auto Show; and obviously never produced.
