Super Sport, or SS, is the signature performance option package offered by Chevrolet on a limited number of its vehicles. All SS models come with distinctive "SS" markings on their exterior. The SS package did not come with "Superchargers" or "Turbochargers" stock with any of the vehicles made throughout the years. Though 3800 series are notorious for having the Supercharged package with them. The SS package was first made available for the 1961 Impala. Some of the other models bearing the SS badge include the Camaro, Chevelle, El Camino, Impala, Monte Carlo, and Nova. Current SS models are produced by the GM Performance Division.
General Motors Company's Australian subsidiary Holden offers SS models in its range of Holden Commodore Sedans and Sportwagons and also in the Holden Ute range of two-door coupé utilities.
In 1961, the SS "kit" (known as a sport and appearance package) was offered on any Impala for just $53.80. The package included Super Sport trim for both the interior and exterior, chassis reinforcements, stronger springs and shocks, power brakes, spinner wheel covers, and narrow-band whitewall tires. The car's dashboard received a Corvette style passenger hand bar and a steering column mounted 7000-rpm tachometer. Chevrolet built 491,000 Impalas that year and 453 had the SS package, of which 311 received the 348 cid and 142 received the 409 cid. Since 1994, the SS package has been used on a variety of GM vehicles, including pickup trucks, four-door sedans, and front wheel drive cars.
