Ferruccio Lamborghini's love of bulls was so strong that he would often visit Don Eduardo Miura who was the owner of a famous bull ranch in the region of Seville and who bred several species. It was this passion that led him to name several of his cars after various breeds of bull which were reared on this ranch. In 1966 at The Geneva Motor Show an early prototype car called the P400S received so much attention that it went in to production under a different name as the Miura a 4 litre car with 280 bhp which is named after a savage breed of Bull bred by Don Eduardo Miura himself, and several variations followed including the SV Concept, Roadster, SV, and the Jota A replacement for the Miura was to become the Islero 400GT and Islero 400GTS a 2+2 coupe which was built between 1968 and 1969 and was named after the bull that killed the famous matador Manolete in 1947.
The Espada which is the Spanish word for Sword appeared in 1968 at the Geneva motor show and was designed by Marcello Gandini of Bertone the famous car designer who designed several cars for Lamborghini Other cars which had names related to bull fighting were the Jalpa which made its debut at the Geneva Auto Show in 1981 and was named after a breed of bull. In 1990 Diablo was named after a famous bull fight in 1869 when the Duke of Veragua's raging bull was in an epic battle with El Chicorro.
There is also a convertible version called the Lamborghini Gallardo Spyder and this really brings the lunacy back. The Gallardo was a high performance car but it was practical and sensible. This version is still practical and is meant to be quiet at low speeds.
