The Citroën C15 is a panel van produced by the French manufacturer Citroën from late 1984 until 2005. It was the successor to the Citroën Acadiane, which had replaced the Citroën 2CV vans that pioneered the box van format from the 1950s to the 1970s, although the Acadiane continued in production alongside the C15 initially. The name refers to the car's French gross vehicle weight rating and indicates its position beneath the C25 and C35 in Citroën's commercial vehicle range at the time. Design The C15 was based on the Citroën Visa (discontinued 1988), and mainly used a 1769 cc XUD or 1868 cc (DW8 on late models), naturally aspirated (non turbo) diesel engine. Until the early 1990s, it was also available with a petrol PSA TU engine. At the time of introduction, the engines were the XUD (C15D) or the 1124 cc petrol TU1 (C15E). The diesel engines also powered vehicles several classes larger. Both Bosch and Lucas/CAV/Roto diesel injection systems were used. The TU petrol-engined versions were sold until the beginning of the 1990s. The engines and drivetrains were taken from the Citroën Visa lineup. While the car was mostly the same as a regular Citroën Visa ahead of the B-pillar, the cargo area was unique. The C15 had a lengthened wheelbase, and a sturdier rear axle shared with the Peugeot 305 Break and Citroën BX since it had to carry heavier loads than the Visa. The very curved sides of the windscreen, enabled the use of a very large single wiper on the long narrow windscreen, without it catching the windscreen seal. The shape of the bumper and plastic trim on the front of the van, like those of the Visa car, were designed to aerodynamically reduce the deposition of dirt on the headlights, and to reduce the risk of stone chips to the headlights, bonnet and windscreen. The heating and ventilation system, (even though it used only a water control valve for temperature control and not air mixing), could provide cold air from fascia side vents, to the face while warming the car. The central directable fascia vents could be pointed directly at the windscreen in front of the driver, to blow hot air to keep it clear in extreme misting conditions. There was also an additional mid-level vent. The C15 also had height adjustable halogen headlights, and multi speed/intermittent front wipers, which was better than
