The 2CV and it's 2 engine sibling ("desert beast") were made to rather special requirements. "Citroen's 2CV is among the most evocative of French icons. A small-engined, medium-sized car designed to provide realistically-priced transport to rural France, the 2CV launches in 1949 to assist in the country's postwar reconstruction.
Famously, it had to be capable of tansporting four people or two farmers with a 50-kilogram weight of baggage (a bag of potatoes) across a ploughed field, without breaking the eggs that they carried with them in a basket. It was to have a maximum speed of 65 kilometers per hour." Taken from

The 2 engine thingy was designed for military use or desert use, where they added redundancy to the 2CV formula (2 engines, gearboxes and fuel tanks).
