Lamborghini Islero (Ultimate Guide)

Lamborghini Islero. The 400GT Replacement.

The Lamborghini Islero was the replacement for the Lamborghini 400GT. The car debuted at the 1968 Geneva Auto Show and was named after a Miura bull. The 340 bhp, 3.9L DOHC V-12 engine had six Weber carburetors, a five-speed manual transmission and four-wheel independent suspension. 

In 1969, Lamborghini improved their 2+2 with numerous changes including a slightly more powerful 350 bhp V12 engine. With many upgrades to the mechanics, aethetics and interior, the Islero S was a much better and was sometimes called the Islero 400 GTS.

Outwardly, the car received slightly flared wheel arhces, an enlarged hood scoop, horizontal side fender vents, 3/4 windows in the doors and two driving lights in the front grill. Inside the new flat dashboard had a functional glove box and rocker switchgear but was less interesting than the early model.

Under the skin a new rear suspension and larger disc brakes were part of the package. The engine sourced bits from the Miura S including its hotter cam and higher compression. This meant 340 to 350 bhp was on tap which was good enough for 0-60 mph in 6.2 seconds.

Like the preceding Islero, the S model used a variation of the 400 GT 2+2 square-tube chassis with a wider track to accommodate the Campagnolo wheels. The model was outfitted with leather interior, power steering, air conditioning and power windows.

Sold alongside the Miura S, only 100 examples of the Islero S were made.
