Lamborghini 350 GT (1964-66)

Based on the 1963 350 GTV Concept, the Lamborghini 350 GT was the first production vehicle produced by Lamborghini. 

Production started in May 1964, after its well-received debut at the March 1964 Geneva auto show.  

The original Bizzarrini-designed 3.5 liter V12 in the 350 GTV Concept was essentially a race motor, 

potentially developing 342 bhp. However it was too large to fit into the chassis of the 350 GTV Concept 

at the time of it's debut presentation. The subsequent 350 GT production car was fitted with a "detuned" engine. 

It was a very capable 270 bhp power plant that could reach 254 km/h (158 mp/h) in top form. 

The manufacture of the bodies was entrusted to Touring of Milan, who used their patented Superleggera 

method of construction to fix aluminium alloy panels directly to a tubular structure.  

Lamborghini produced 135 350 GTs before replacing it with the larger-engined Lamborghini 400 GT in 1966.
