The car was powered by a French four-cylinder CIMA engine with a Cozette carburettor. The car proved to be reliable, strong and with high acceleration.

Also note that a single vehicle can be sold concurrently under several nameplates in different markets, as with for example the Nissan Sunny; in such circumstances manufacturers often provide only cumulative units sold figures for all models. As a result, there is no definitive standard for measuring units sold; Volkswagen has claimed its Beetle as the bestselling car in history as it did not substantially change throughout its production run. By contrast, Toyota has applied the Corolla nameplate to 11 generations since 1966, which have sold over 40 million through July 2013.
