The Innocenti Spider originally sold well in Italy, with production running at 13 cars per day in 1962, but it had a hard time competing against the cheaper Sprite in export markets. As more modern competitors arrived and as the British-built Sprite was modernised, sales dropped precipitously, with only 63 cars built in 1965. Thus, Innocenti presented the reworked Innocenti Coupé in September 1966, still with the same 1100 engine as seen in late Spiders. The badging on the car simply read "Innocenti C". The Coupé's all-new bodywork was wider and longer than the Spider's, and the wheelbase was extended by 150 mm to . The floorpan was reworked to allow for the seats to be mounted lower than in a Sprite, making the cabin less cramped. It was competitively priced in the Italian market, slotting nicely between the smaller Fiat 850 Coupé and the bigger Fiat 124 Sport Spider. It cost 1,190,000 lira, versus 950,000 for the 850 Coupé and 1,550,000 for the 124. Only 794 were built when production ended in 1968.
