After a few prototypes derived from other models, Lamborghini finally decided to produce a car with a removable roof. The Urraco Chasis was used as a starting point for this new project. The Silhouette was introduced at the March 1976 Geneva auto show, where it received a favorable reception. The interior design of the Silhouette resembled the Urraco, but it was a strict two seater. Its exterior had a more aggressive appearance, while it interior contained gauges that were easier to read. It could travel from 0 to 60mph in seven seconds. The Silhouette could not be sold in the United States because it did not meet the new, stricter safety and anti-pollution legislation. Production was halted in 1978 after only 58 were built.
