Super Sport, or SS, is an option package offered by Chevrolet on many of its vehicle lines since 1961. Some of the better-known models to bear the SS badge include the Camaro, Chevelle, El Camino, Impala, and Nova. Originally introduced in 1961 as an appearance package for the Impala, it became a high-performance package in 1966.
Until the Impala SS was brought back in 1994, the Super Sport package was only available on two-door passenger cars. Since then, however, 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. All SS models have come with "SS" markings.
Newer SS models are the Chevrolet Cobalt SS, Chevrolet HHR SS, Chevrolet Impala SS, Chevrolet Monte Carlo SS, and the Silverado SS, along with the Trailblazer SS. Current North American-market SS models are tuned by GM Performance Division. The Impala SS is slated to replace the Monte Carlo SS in NASCAR racing, as the latter is being put on hiatus.
In 2003, Chevrolet released a concept car they named the SS. A rear wheel drive sports car with a modern 430 hp small-block V8 engine and race-tuned suspension, it was billed as "a modern interpretation of Chevrolet's Super Sport heritage." Though never intended for production, the vehicle was used as a show car and to hint at what was ahead for Chevrolet sports car design. It could possibly become a future version of the Corvette.
