American, the car name is Chevrolet SS

Chevrolet SS, but SS is not a car, it is super sport, that is, Chevrolet's super sports car (based on the original car, such as Chevrolet Camaro (Bumblebee in Transformers) and Camaro SS) is similar to BMW's M series, Audi's S and Mercedes-Benz's AMG, that is, high-performance cars. There are many SS, and many cars (Chevrolet) have SS models, and the most common (most often heard) should be Camaro SS.
