Where does American muscle come from?

Likening muscle to horsepower, American performance cars were first calledÌýmuscle cars in the 1960s. A 1965 issue of Popular ScienceÌýnoted how the option of a high-horsepower Hemi-426 engine made the Dodge Coronet aÌýmuscle car. Car and Driver used the same term to describe the Pontiac GTO. Notable models of Buick, Chevrolet, Ford, and Plymouth cars, all of which tend to be two-door sports coupes, were also designated asÌýmuscle cars during this period.
In 1977, as car imports were increasing in the United States, theÌýComplete Guide to American Cars described this class of vehicle asÌýAmericanÌýmuscle.ÌýCar and DriverÌýwould call it “uniquely American” in 1985, so use ofÌýAmerican muscleÌýemphasizes the car’s American-ness as way of differentiating it from other vehicles (e.g., Australian muscle cars).
American muscle began to take on an element of nostalgia in the 1980s. A business journal article from 1983 asked “Remember American muscle cars?”ÌýCar and DriverÌýmade reference to “good ol’ American muscle machinery” two years later.
This nostalgia continued into the 2000s. A 2003 letter toÌýRoad and Track, for instance,Ìýasked if a resurgence of great American cars was coming in response to an article titled “American Muscle.”
