21. Citroen 2CV
They presented the first Citroen 2CV in 1948. Soon, it became a bestseller, not only in France but also in the rest of Europe. The early models had a diminutive flat twin engine with only 375 CC (21 CID) that delivered only nine horsepower. But later versions grew to 600CC (40 CID) to produce 29 HP.
Despite its diminutive power and performance, the Citroen 2 CV was immensely popular all over the world, selling in almost four million copies. Citroen sold it briefly in the USA, but it didn’t attract much attention from car buyers. Simply, people thought the car was too strange, underpowered, quirky, and ugly.
