The RB15 was Red Bull Racing's Formula 1 car for the 2019 season, the team's first car powered by a Honda V6 turbo hybrid engine. That switch made its engine note a talking point among fans, who shared clips of its high revving sound from testing and race weekends. The recording has since circulated on soundboards alongside F1 radio clips as a shorthand for modern Formula 1 power. It remains popular because the V6 scream is instantly recognisable, even though the cars themselves have moved on to later designs.
