Chevy muscle cars are American muscle cars produced by Chevrolet from the late 1950s onwards. They are typically characterized by powerful V8 engines, a wide stance, and a bold and aggressive design. Popular models include the Impala, Camaro, and Chevelle. Pony cars are similar to muscle cars, but with a smaller size and engine. The term was first coined to describe the Ford Mustang, although other automakers such as Chevrolet, Dodge, and AMC have created their own versions. These cars are typically characterized by a low profile, long hood, and short rear deck. Popular models include the Mustang, Camaro, Firebird, and Challenger.
