by RhiannaJ

General Motor Company produced the first Sierra in 1975 as a full-size pick-up truck for the Chevrolet C/K trim. The name Sierra differentiated the various trims in this line, such as the Sierra Classic and Sierra Grand. The letter K denoted the model which had four-wheel drive, and the letter C the rear-wheel drive models. The year 1985 brought the adjustment of the exterior designs, and the launch of a new engine technology which was an improvement over that of previous models.
