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 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, Nova and Chevrolet Pickup Trucks. 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. History In December 1956, Chevrolet unveiled a show car based on the first generation (C1) Corvette called the Corvette Super Sport. In early 1957, the Chevrolet Corvette SS debuted — a custom built racing sports car that was the first Chevrolet to wear the SS badge. 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. Both historically and today, the Super Sport package has typically included high-performance tires, heavy-duty suspension, and increased power, along with a variety of other performance and appearance upgrades.
