 The urgency of the project was increased in the summer of 1956 when the Simca chief learned of a dastardly plan by Paul Ramadier, the Minister for Economy and Finance, and a still influential former prime minister, to introduce in December 1956 an additional savage annual car tax for owners of cars with larger engines.The Suez crisis simply built on the economic case for a small engined version of the car, and Simca was therefore ready to respond very nimbly to the changed circumstances created by the crisis, fitting a 1290cc "Flash" series engine from their successful small family car, the Aronde, into the most basic version of their V8 engined Simca Trianon, which was one of the models in the Vedette range.The new car was badged as the "Simca Ariane" and was soon available in several versions.
