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.

Origins Of The Impala SS

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.

Engine And Styling Choices

From 1965-1970, the 4th generation models would be offered with 9 engine choices. Unfortunately, sales for the SS model were steadily decreasing, prompting fewer options for the ‘66 model year. The SS badge was only available with the 427ci engine. Small design changes were made, including the transition from round to rectangular taillights and chrome accents.

1967 models would be designed with the distinctive “coke-bottle” styling. The 1967 model incorporated the first lighted fiber optic ignition switch. 1969 was the last year for the fabled Impala SS, which was offered with a Z24 package. This included the 427ci V8 with power ranging from 335 to 425 horsepower. The discontinuation of the model would mark the end of an era, as the Impala would gradually evolve into a more prosaic sedan.

Many have considered the Impala SS to be the first real muscle car. Whether this is the case is to be debated, but the Impala SS makes quite the case. Its styling embraces many characteristics of what makes up a truly classic muscle car.  The Impala has appeared countless times in movies and TV, and it is still the subject of references in pop culture.

The powerful engine offered in the Impala SS was quite impressive for its time; Chevy’s 409 would become a legend in itself.  Although the term “underrated” seems overused, the Impala SS was oft disregarded in its time. Today, we look back at the Impala SS as a classic piece of history with plenty to offer.
