Lamborghini Countach LP 400S

The Countach's styling and visual impression caused it to become an icon of great design to almost everyone except automotive engineers. The superior performance characteristics of later Lamborghini models (such as the Diablo, or the Murciélago) appealed to performance car drivers and engineers, but they never had the originality or outrageousness that gave the Countach its distinction. The different impressions left by the various Lamborghini models have generated numerous debates and disagreements over what constitutes "classic" or "great" automotive design (elegant looks and style, versus technical and engineering superiority).
Engine
The rear wheels were driven by a traditional Lamborghini V12 engine mounted longitudinally with a mid-engined configuration. This contrasted with the Miura, on which the centrally mounted engine had been installed transversely. 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 litres (1.1 imp gal; 1.3 US gal) 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.
