From classic, elegant styling to pioneering power and performance, the Impala SS is one of the most legendary muscle cars of all time. The Chevrolet Impala SS was released in 1961 and the base model itself went on to span 10 generations. In the mid-1960s, modifications to the frame were made which resulted in an iconic Impala style easily recognizable today.
Impala models produced in the late 1960s could be considered part of the fourth generation, which was arguably the most coveted. Many body styles and engine choices were offered as well, enhancing its popularity. Even in modern times, the Impala SS is one of the most exquisite choices for restorations and a hallmark of many classic car shows. Let’s take a look back at the ‘65-’70 Impala SS models and their remarkable heritage.
In 1961, the first Super Sport package on the Impala was offered for a price of just $53.80. Along with a more powerful engine, this package included better suspension and power brakes. Original SS models are incredibly rare, as just 142 were sold with the upgraded engine. The package included a 409ci V8 as standard, capable of 360hp and 409lb-ft of torque. This particular engine would last until around 1965 when it was succeeded by the 396ci Mark IV V8 with a Turbo Hydra-Matic 350 transmission.
The mid-1960s model presented revolutionary modifications in the aesthetic department with the elimination of the classic X-frame design. The X-frame, which posed significant safety concerns, would be replaced by a perimeter frame. The design change marked an important milestone in Impala history. Post-1965 models were visually different and embraced a sleek form factor.
