The sound comes from the Lego Star Wars video games, where podracers are the small, fast hover vehicles raced in the Star Wars universe. In the games, podracing levels are known for their speed and tight turns, and the engine noise became a shorthand for that chaotic racing feeling among players. Shared as a short clip online, it is now reused by editors and meme creators who want an instantly recognisable racing sound without using dialogue, music or a realistic car engine.
