The fourth-generation Crown was placed on the market in February 1971, when the model name was changed from Toyopet Crown to Toyota Crown. The available body types included a 4-door sedan, a 2-door hardtop, and a 5-door wagon -- the same as the previous model generation.

The fourth-generation Crown inherited the mechanical components, including the perimeter frame and the engine, from its predecessor. The most notable change was in its body design. The spindle-shaped body that tapered toward the front and the rear was uniquely avant-garde, and was expected to appeal to individual customers who had been eagerly solicited ever since the marketing campaign for the third-generation Crown began. However, the styling attracted neither the individuals nor the conservatively inclined corporate and institutional users, and the Crown slipped from the class-leading position for the first time since 1955.

The fourth-generation Crown further diversified its model grades by introducing the top-of-the-line Super Saloon. In May 1971, the 2600 Super Saloon powered by a 2,600 cc engine (4M) was added to the line, and more models came equipped with the 4M engine in October 1972. In October 1973, the unpopular styling was modified in a facelift. In January 1974, the SL and Super Saloon grades offered additional models equipped with the 2000 EFI engine.
