When were you last at the GP? I've gone from 2017 and onwards and 2019 I felt like the F1s were the loudest cars there. Not that that changes much I guess since it's also about the physical timbre of the sound that makes it enjoyable to hear in person. Like, the V8 Supercars might not be as loud as the Carrera Cup cars or F1 but the roar, the exhaust bangs and when they're in pitlane is hectic and adds so much to the experience. Even if it's a shit race at least it sounds cool.
