My mechanic told me the future of racing is hydrogen. You gotta have noise.

You really dont though, turbos cut the noise in half in the recent years and it's considerably nicer to watch a race.

Recently, the gt3 Porsche cup at an F1 event; you need earplugs for the gt3s 1000' away, but the F1 cars you can have a conversation, not damage your hearing (because of the turbos)
