Lower pitch is the least of my worries. I thought the V10's sounded very good (like an angry bee), but the V8's are unremarkable.

This is the greatest sound in the history of the world, bar none. When that flat-twelve gets to the top it sounds absolutely window-licking mad. No need for 20 000 revs. This is indescribably good.
It's a shame that car never won a championship. If I could only drive one F1 car it would be that one. It's a pretty sexy beast to boot.
