The Super Sport was known as Regular Production Option (RPO) Z03, from 1962 to 1963, and again in 1968. From 1964 through 1967, the Super Sport was a separate model, with its own VIN prefix (for V8 models, 168 versus the 164 for the regular Impala). Super Sports from 1962 to 1964 came with engine-turned aluminum trim, which was replaced by a "blackout" trim strip in 1965 which ran under the taillights. 1965 Super Sport exteriors differed only slightly from regular Impalas.
"Super Sport" scripts replaced the "Impala" fender badges. The new center console housed a rally-type electric clock, and full instrumentation now included a vacuum gauge. A total of 243,114 Impala SS coupes and convertibles were built for 1965.
The 1966 Impala SS was facelifted with a revised grille and new rectangular taillights that replaced the triple round units. A chrome beltline strip shared with regular Impalas was added in response to complaints about door dings on the clean-lined 1965s.
