Released at the 1976 Geneva Motor Show, the Silhouette was a targa-style version of the Urraco P300. It was Lamborghini’s first open model which used a removable roof that could be stored behind the rear seats.
To accommodate the new roof, significant changes were made to the Urraco structure to increase rigidity. Bertone was commissioned to restyle the body and make room for the ultra-wide Pirelli P7 tires. They added new wheel arches, a distinct front dam with ducts for the oil cooler and brakes. The rear had a unique window treatment that was really an oversize hoop to hide the roll-bar.
Behind the passenger’s sat a mid-mounted, quad-cam V8 engine which was good for 265 bhp. Since Lamborghini was not importing cars at the time, only a few cars were sold in the grey market to America, and all versions had 265 bhp for the European market.
While the intention was to revive the Urraco model, only around 50 Silhouettes were ever manufactured. Later, Lamborghini released the ultimate version known as the Jalpa.
