An updated Islero S, was released in 1969. The engine in this model is tuned to 350 brake horsepower. There are some styling changes, including brightwork blind slots on the front fenders, an enlarged hood scoop (which supplies air to the interior of the car, not the engine), slightly flared fenders, tinted windows, round side-marker lights (instead of teardrops on the original), and a fixed section in the door windows. Various other changes includes larger brake discs, revised rear suspension and revamped dashboard and interior. Only 100 examples of the Islero S were built, bringing the production total of the Isleros to 225 cars.
