During 1965, Lamborghini's three top engineers,
Gian Paolo Dallara,
Paolo Stanzani, and
Bob Wallace worked at night on their own time to develop a road car with a racing pedigree.
The three men hoped to talk
Lamborghini out of his opinion that such a vehicle would be too expensive
and would distract from the company's focus.
When the engineers admitted their secret, the company gave it the go ahead as a marketing tool. The prototype P400 debuted at the 1966 Geneva show and the car
received a stellar reception. The 170mph design started a trend for mid-engined supercars and the rest is history.
