AUDI RS4 from carl bouteiller on Vimeo.
tastes change. sure, these sound great, and it goes without saying that i'd take one in a heartbeat, but in the end, i think i prefer the sound of an e90 m3, even an e46. i used to think deep, basso profondo V8s sounded the best, but the more i'm around these cars, the more i think i prefer the higher-pitched wail of the bmw engines. the audi and amg v8 engines are impressive but ultimately still sound like they belong in street cars; the e46 and e90 m3 engines legitimately sound like they could belong in race cars. and that just appeals to me tremendously (although i understand completely how the average non-car person could prefer the rs4's and m-b's more muscle car-like snorts).
I agree - the S54 and S65 are probably better sounding engines. I like that both translate into racing engines or come from them. According to BMW - there isn't terribly much that separates the S65 and the V8 that powers the ALMS car. Can't go wrong with that. However, I have a hard time snubbing the noise and sheer grunt of the Benz V8's if they're the German thug of the group then the BMW V8 is the athletic one - powerful and loves to run!
trying to decide which one i like best :)http://www.youtube.com/watch?v=IfOb57I_c8Ai prefer this to the rs4. *unthinkable* just a couple of years ago. i initially really disliked the high-pitched, metallic-sounding s54. so this is just a complete 180 for me.
