Oh Yes, very cool, not sub zero, but definitely cool
Pierre Boulanger, the father of the 2CV, set a brief to his Chief Engineer, Maurice Broglie, for a new car to be codenamed "Becassine" (snipe) to be an "umbrella on wheels" to carry two farmers, along with 50kg. of potatoes or a small barrel of wine at a maximum speed of 60 km/hr. It must travel in good comfort over rough rural roads. Economy was to be a priority - less than 3 litres of petrol was to be used to cover 100 km., and the car must cost less than one third of the then current Traction Avant.
By 1936, a fullsize wooden mock-up had been made. Boulanger was tall, and was unhappy with the headroom. He ruled that the car should be modified to allow him to drive wearing a hat. A first prototype appeared early in 1937. The body was aluminium for lightness, wheels were magnesium, the windows made of mica. Hammock- like seats were suspended from the roof by cables. Since the new engine had not been tested, a BMW 500 cc. motorcycle engine was used instead, the kickstart being operated by the starting handle.
By the end of 1937, 20 prototypes had been produced. Secrecy was important to the project, and cars were tested at Bois de Meudon, near Paris. An old chateux at La Ferte-Vidame, east of Paris, had the grounds converted to a 2.5km. test track.
With the occupation of France, Boulanger was concerned the project would fall into the hands of the Germans. He ordered the remaining cars to be destroyed. However, development continued in secret and some prototypes survived. The aluminium body was finally shelved in favour of light guage steel. The innovative suspension for which Boulanger defined a specification to enable the car to carry a basket of eggs without breakage across a ploughed field was developed, electric start was added, a single headlight was deemed sufficient initially bit was later given a partner, and a heating system was added.
So, on the 7th October 1948, at the 35th Salon de l`Automobile, after a gestation period of 13 years, the 2cv was born. The press and public found the car very strange but irresistable. The car was however accepted as being well needed in austere post-war France, and when production started in earnest in 1949, demand was very heavy. Citroen had cornered a niche market, a market that other manufacturers did not know existed. The car was very comfortable, it could be driven up and down steps at 20mph, across ploughed fields. It rapidly became part of the fabric of French life. Farmers and country dwellers were the primary market, but town dwellers were also desperate to buy 2cvs. Demand exceeded supply. In 1949 only 924 cars were made but this rose to over 6000 the next year.
The rest as they say is history....
Which reminds me....
