Currently this show car can be seen on various events with its first styling. 500 Superfast The end of the top-line America series was the 500 Superfast, first shown on the Pininfarina stand at the March 1964 Geneva Motor Show. During development these cars were to be called "Superamerica", but the decision was made at the last moment to use "Superfast" instead. The engine was a unique Ferrari Colombo V12 engine, which had the same 108 mm bore center dimensions as the Lampredi "long-block" engines of the 410 Superamerica, otherwise the design was based on the original Colombo "short block". Breathing through six twin-choke Weber 40DCZ/6 carburettors, the V12 produced at 6,500 rpm and could push the car to . The chassis was very similar in construction to the contemporary 330 GT 2+2, and bodywork was again done by Pininfarina. When leaving the factory the 500 Superfast originally fitted Pirelli Cinturato CN72 205 VR15 tyres. 36 cars were made from 1964 to 1966, including 12 improved models with a 5-speed transmission in place of the earlier 4-speed plus overdrive. This production total excludes a one-off 330 GT 2+2 produced with a Superfast-style body for Prince Bernhard of The Netherlands. This one-off car sold at Bonhams' December 2003 Geneva auction for CHF 422,100 inc. premium. Only coupés were made and no Superfast roadsters
