In the name Lamborghini 350 GTV, the letter V stands for Veloce, the Italian word for “fast.”
The badge expands to Gran Turismo Veloce: “350” referred to the engine’s roughly 3.5-litre displacement, while “GT” identified the car as a grand tourer. The Veloce suffix distinguished the prototype’s sporting intent.
The 350 GTV was Lamborghini’s first car, presented in 1963 and designed by Franco Scaglione. It used a 3.5-litre V12 and served as the prototype for the 350 GT, Lamborghini’s first production model. The production car was called 350 GT rather than 350 GTV, so the Veloce wording belongs specifically to the prototype name.
A common mix-up is “Velocità,” another Italian word associated with speed. However, the documented expansion of GTV is Gran Turismo Veloce, making Veloce the canonical answer.
