The Sierra debuted at the 1982 Paris Motor Show. Contrary the taut lines of the BX, introduced at the same time, the Sierra has soft curves, designed by Patrick Le Quément, who ended his career at Renault. This 3-door XR4i version of the Sierra, equipped with a double spoiler and a 150 hp 2.8-litre V6, was launched in March 1983. This model was replaced in March 1985 by the XR4x4.
