The Lamborghini 350 GTV is a Lamborghini prototype and forerunner of the automaker's first production model, the 350 GT. It was first presented to the public at the 1963 Turin Auto Show. Development The design and development of the 350 GTV was overseen by Lamborghini chief engineer Gianpaolo Dallara, assistant Paolo Stanzani and test driver Bob Wallace, the core engineering team that developed many early Lamborghini cars. Giotto Bizzarrini was commissioned to design the engine and an early version of the chassis. The 350 GTV's name signified the 3.5 L displacement of the engine, the "GT" for grand tourer and the "V" for the Italian word "Veloce" (meaning "fast"). The 350 GTV body was designed by Franco Scaglione and built by Carrozzeria Sargiotto in Turin. Ferruccio Lamborghini's opinion had a significant amount of influence on the design. He reportedly requested styling echoing the Aston Martin DB4's tapering rear bodywork and the sleek front of the Jaguar E-type. The 350 GTV had many styling details that were unusual at the time of its introduction, including hidden headlamps and six exhaust tailpipes (three on each side of the car's rear). The body was constructed of aluminum and steel. As workers at Sargiotto were primarily skilled in building molds for plastic products, the 350 GTV's body had numerous fit and finish issues. Initially, Bizzarrini designed a racing-style tubular spaceframe chassis for the 350 GTV. Giorgio Neri and Luciano Bonacini built the tube frame chassis in Modena. This design was later reworked by Dallara into a more conventional, heavier design constructed of mostly square and rectangular section tubing that would be used in the production 350 GT. Ferruccio Lamborghini commissioned Giotto Bizzarrini to develop the 350 GTV engine. This was the first iteration of the Lamborghini V12 series of engines, which would power future Lamborghini models up through the end of Murciélago production in 2010. Bizzarrini developed a 3.5 litre racing-specification V12 engine, with an output of at 8,000 rpm, and torque of , using the DIN measurement standard. This design was derived from Bizzarrini's plan for a 1.5 litre Formula One racing engine. Top speed was claimed by the factory to be , although this was an estimate as the car was never driven or tested by the factory. This engine had a compression ratio of 9.5:1 and relatively aggressive valve timing compared to later versions of the Lamborghini V12. The higher redline,
