The Porsche 911 GT3 R is Porsche's dedicated customer racing version of the 911, built for GT3-class competition around the world. Its naturally aspirated flat-six engine is famous for its screaming high-rev soundtrack, and engine recordings like this one circulate widely among car enthusiasts as downloadable ringtones and soundboard clips. Because the sound is instantly recognisable to motorsport fans, it keeps showing up in car edits, racing game montages and meme videos, long after the clip itself was first shared.
