do those have the airbag suspension like the DS?

France at that time (1934) had a very large rural population which could not yet afford automobiles; Citroën used the survey results to prepare a design brief for a low-priced, rugged "umbrella on four wheels" that would enable four small farmers / peasants in clogs to transport 50 kg (110 lb) of farm goods to market at 50 km/h (31 mph), if necessary across muddy, unpaved roads. The car would use no more than 3 liters of gasoline to travel 100 km (78 mpg ). One design requirement was extremely light weight. Another was that the customer be able to drive eggs across a freshly ploughed field without breaking them.

That looks like so much fun.
