This concept basically invented the minivan/MPV (no sliding doors, but most European MPVs don't have them).
After Fiat/Lancia passed on putting it into production themselves, multiple manufacturers took note and began working on their own production versions. The Japanese were actually the first to market with the 1982 Nissan Prairie and 1983 Mitsubishi Chariot. The Americans and Europeans were next: Chrysler launched the 1984 Dodge Caravan and Plymouth Voyager, while Matra and Renault launched the 1984 Renault Espace (it was designed by Matra and originally intended to be sold by PSA as a Talbot... but PSA killed the Talbot brand and with it their partnership with Matra at the last minute, so Matra took the design to Renault).
