The Countach was styled by Marcello Gandini of the Bertone design studio, the same designer and studio that designed the Miura. Gandini was then a young, inexperienced designer—not very experienced in the practical, ergonomic aspects of automobile design, but at the same time unhindered by them. He produced a quite striking design. The Countach shape was wide and low (42.1 inches), but not very long (only 163 inches). Its angular and wedge-shaped body was made almost entirely of flat, trapezoidal panels.
1982 saw another improvement, this time giving a bigger, more powerful 5 litre engine. The bodywork was unaltered. This version of the car is sometimes called the LP5000S, which may cause confusion with the later 5000QV (next section).
