Dr. Simeone talked about what makes the incredible 12 cylinder engine so special. He also had 3 special racing sports cars featured, whose V12 engines make beautiful sounds the equivalent of an automotive symphony orchestra. Featured in the Demo Day were the 1933 Auburn V12 Speedster, 1954 Ferrari 375MM, the Bizzarrini Spyder, and the 1975 Alfa Romeo Tipo 33 TT 12.
