Lamborghini Countach LP 400S

The pure style of the prototype was progressively altered by the evolution of the car to improve its performance, handling, tractability, and ability to meet mandated requirements. This began with the first production model, which included several vents which were found to be necessary to cool the engine adequately. These included the iconic NACA duct on the door and rear fender of each side of the car. The car design changes ended with a large engine vent directly behind the driver, reducing the rear view. Later additions, including fender flares, spoilers, carburetor covers, and bumpers, progressively changed the aesthetic values of the car.
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).
