Following the Federal Highway Act of 1956, the need for capable cars increased dramatically. In order to make a vehicle faster, bigger, and more powerful than the Bel Air, the Chevrolet Impala was born. Over the history of the Chevrolet Impala, the car has evolved dramatically. The Impala wasn’t always successful, either. This car was eliminated and re-introduced multiple times. Today, the Chevy Impala is a successful full-size sedan in Chevrolet’s impressive lineup. It’s been 58 years since the first Impala, so let’s take a look back at the history of the Chevrolet Impala Through the Years.

Good article overall, but I’d like to suggest a few edits. Although I can imagine how much fun a 5th-gen would have been with a twin-turbo 454, that engine was naturally aspirated. Same for the 8th-gen police package, which I can imagine would have been more popular with law enforcement if it had the same supercharged 3.8L as the SS. Instead, it got a naturally aspirated 3.8L. Also, and this might be a bit pedantic, engine displacement for early-80s and older engines is properly written in cubic inches instead of liters, such as the base 283 in a ’58 or the 409 in a ’62 SS. My suggestion would be to write the displacement of these older engines in proper form with liters in parentheses, such as “283 CI (4.6L).” Other than these minor errors, this is a good article and I appreciate the research that went into it.
