There's a lot of debate around this, but we believe before the seventh generation (C7; 2014 - 2019) Corvette, it was a muscle car. The C6 and older Corvettes had the right muscle car recipe: simple V8 up front, rear-wheel drive, and relatively low-tech. The C7 Corvette was far more high-tech and many regards it as feeling more like a European sports car. And of course, the current-generation C8 Corvette is a mid-engine supercar and is not a muscle car.
