The C15 was based on the Citroën Visa (discontinued 1988), and mainly used a 1769cc XUD or 1868cc (DW8 on late models), naturally aspirated (non-turbo) diesel engine. Until the early 1990s it was also available with a petrol PSA TU engine. As well as standard van configuration, the vehicle was available with rear side-windows and a rear seat, (which had been pioneered in the 2CV), which can be seen as a forerunner to today's utility vehicles such as the Ford Transit Connect, Opel/Vauxhall Combo, Citroën Berlingo and Peugeot Partner. The C15 was available without the rear box section, as a 'chassis only' model. Rare pickup truck versions were also made.
