The Chevrolet Nova SS is a performance-oriented variant of the Chevrolet Nova, produced by the American manufacturer Chevrolet. The “SS” designation stands for “Super Sport,” a badge used by Chevrolet to identify higher-performance models. The Nova SS was primarily produced during the 1960s and 1970s, a period closely associated with the rise of American muscle cars.

The Nova SS typically featured more powerful engine options than standard Nova models, including high-output V8 engines. It was often equipped with upgraded suspension components, sportier exterior trim, and performance-focused features. The model emphasized strong straight-line acceleration and was positioned as an affordable entry into the muscle car segment.

Over time, the Nova SS became associated with classic American performance culture. While the broader Nova model line evolved and was eventually discontinued, the SS variants remain recognized as notable examples of mid-20th-century American performance engineering.
