At the I Alcohol Automobile Fair in 1983, the company, then known as Polystilo Indústria e Comércio, unveiled a brand-new vehicle designed by Wladimir Martins. The vehicle, called Savannah, was a two-seater convertible with a front engine and Chevrolet mechanics. It was built on its own platform, which was 25 cm shorter than that of the Opala, utilizing elements from the Opala. The Savannah was available with either a 2.5 or 4.1-liter gasoline or alcohol engine, with options for automatic or manual transmission with four or five gears, and mechanical or hydraulic steering. The front brakes were equipped with disc brakes. The body of the Savannah was made of reinforced plastic and featured Opala taillights and a Ford Del Rey instrument panel. The interior boasted special fully reclining seats, velvet upholstery, carpet, a canvas hood, and a removable rigid roof.

In 1986, the Savana project was transferred to Py Motors, who subsequently relaunched it under the name Equus.
