The Citroën Acadiane is a small commercial vehicle produced by the French company Citroën from 1977 to 1987. It was derived from the Citroën Dyane and only available in left-hand drive. Its production totalled 253,393 until its discontinuation.^[1] The Visa-based C15 van eventually replaced the Acadiane.^[2]

The name "Acadiane" was a pun of AK Dyane "Acadiane" because Citroën had already used the prefix "AK" for its light commercials.^[2] There was no connection beyond the pun with the French-speaking region of Louisiana that is home to Cajun (Acadiane) cooking,^[2] or with l'Acadie, now part of Nova Scotia.^{[citation needed]}

The Acadiane differed from the Dyane on which it was based in having heavier-duty suspension, a slightly altered chassis, and a rear-brake limiter whose action was dependent on the load.^[2]

The Acadiane was also fitted with wind-down windows in the driver's and passenger's doors. The Dyane car had horizontally-sliding windows.^[2]

The payload was approximately 500 kg (1,100 lb), but handling was impaired when fully loaded.^[2]

The Acadiane was available in commercial (two-seater) form or as a "Mixte," with sliding rear windows and a removable rear bench seat.^[2] Citroën and many other manufacturers continue to this day (Berlingo et al.) with the option of rear seats in a vehicle clearly designed as a commercial. The Mixte version also had a passenger sun visor, missing in the more basic commercial version. In line with many Citroën light commercials, the roof of the rear bodywork was corrugated to add extra rigidity at little cost.

The Acadiane had an average speed at 55 mph (89 km/h).^[2]

Top gear in the four-speed box was usually referred to as overdrive. This had been used since the earliest days of the 2CV, and was used most of time.^{[clarification needed]} Progress could be maintained in top, but further acceleration was unlikely. As the motor thrived on revs, third made a perfectly good gear to get up to 80 km/h (50 mph). The Acadiane came from the factory with Michelin 15x135 tires, 10mm wider than those fitted to the 2CV and Dyane cars.

The Citroën Geri, a pickup variant of the Acadiane, was produced by Cimos in Yugoslavia from 1981 to 1985.^[3]
