After three years in production, the Vedettes were given new names and a new, elongated body, with a more ornate front end and large tailfins, making the cars even more American-looking than before.
  This was part of a styling trend shown by most large European cars of that period, which were, to some extent, inspired by American styling, as tailfins appeared on Peugeots, Fiats, BMC models (Pinin Farina-styled), Fords and even Mercedes-Benz cars of that era.
The engine was uprated to 84 hp (63 kW) (now called Aquillon 84) but the fiscal qualification of the car remained unchanged.
 Using the new body, the Versailles was replaced by Simca Vedette Beaulieu and the Régence by the Chambord, while the estate retained the Vedette Marly name.

The three-year-old body of the previous Vedette nevertheless continued in production but it lost its V8 2.4-litre engine.
In April 1957, fitted with the 1.3 L Aronde engine, the old body now clothed a new model in the Simca range, the Simca Ariane.
Later, in October 1957, a V8 version of the old bodied car, with the Aquillon 84 engine, and badged as the Ariane 8, joined the range, replacing the Trianon.

1959 brought a new option, the Rush-Matic automatic transmission, which featured two modes: Rush (fully automatic) and Road (manual gear selection).
The same year, assembly of the Vedette started at Simca do Brasil.
Also during 1959, a new top-of-the-line model joined the Vedette range, the Présidence, featuring a luxurious interior, a radiotelephone (a European first) and a continental kit.
French coachbuilder Chapron built two 2-door Présidence convertibles for a governor of one of the French colonies.
Chapron had another order the next year, to build two four-door convertibles for the French President Charles de Gaulle.
The Beaulieu was dropped in autumn 1960, but the other models remained unchanged until the 1961 model year, when they received new seats, new chrome decor, and the engine was fitted with a new anti-vibration crankshaft.

French production of the V8-engined cars ended in the summer of 1961, by when 173,288 had been produced, although a Simca Chambord was exhibited at the Paris Motor Show in October of that year, suggesting that Simca still had some stock of the cars to clear.
  The small-engined 4-cylinder Ariane, of which 166,363 were produced, survived until 1963.

The model was continued for longer in Brazil, where it was marketed with the 2.4-litre V8 under a variety of names like "Tufão", "Jangada", and "EmiSul".
It was eventually replaced by a version with new sheetmetal, called the Simca Esplanada.
