Hellcat whine usually refers to the supercharger sound made famous by Dodge SRT Hellcat models, especially in short car videos and social media edits from the mid-2010s onward. The sound spread because it is instantly recognizable even without seeing the vehicle, and fans often isolate it from driving clips for memes, reels and compilations. It remains popular in automotive content because that sharp mechanical whine signals horsepower, speed and excess more clearly than a generic engine rev.
