There was no connection beyond the pun with the French-speaking region of Louisiana that is home to Cajun (Acadiane) cooking, or with l'Acadie, now part of Nova Scotia.
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.
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.
In line with many Citroën light commercials, the roof of the rear bodywork was corrugated to add extra rigidity at little cost.
The Citroën Geri, a pickup variant of the Acadiane, was produced by Cimos in Yugoslavia from 1981 to 1985.
