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. Gandini again produced another striking design. The Countach shape was wide and low (1.07 metres or 42.1 inches), but not very long (only 4.1 metres or 163 inches). Its angular and wedge-shaped body was made almost entirely of flat, trapezoidal panels.
The rear wheels were driven by a traditional Lamborghini V12 engine mounted longitudinally with a mid-engined configuration. This contrasted with the Miura with its centrally mounted, transversely-installed engine. For better weight distribution, the engine is pointed “backwards”; the output shaft is at the front, and the gearbox is in front of the engine, the driveshaft running back through the engine’s sump to a differential at the rear. Although originally planned as a 5 L (310 cu in) powerplant, the first production cars used the Lamborghini Miura’s 4-liter engine. Later advances increased the displacement to 4754 cc and then (in the “Quattrovalvole” model) 5167 cc with four valves per cylinder.
All Lamborghini Countaches were equipped with six Weber carburetors until the arrival of the 5000QV model, which used Bosch K-Jetronic fuel injection. The models in European markets however, continued to use the carburetors until the arrival of the successor model Lamborghini Diablo, which replaced the Countach.
