V8 Engine
Sorry if this seems like an ignorant question but are the V8's in the new S4 anything like the old 2.8L V6's in terms of being interference engines? i.e., timing belt seizing = booboo for engine and big owiefor pocketbook?

yeah my understanding is this....
Timing belt, alternator and everything else is run off a metal chain belt that drives all of those and doesn't warp, break or bend. Hopefully this comes to be true. I haven't heard of any Euro S4's having problems with this, but they might change something on the way to the US release.... never can tell.

I believe I read that they have a breakaway shaft to protect the chain should any component lock up
One will probably have to pull the engine to fix - but you wont have to buy a new engine.

That's right... I knew there was a catch for working on it...
I remember reading that in European Car one month. However, I'm glad they've replaced the cumbersome "rubber" belts with metal that is guaranteed to work or they'll fix it free of charge.

The camshafts are driven by a chain and gears off the back of the eingine..
not a toothed belt on the front like current engines. Old V12 Ferraris used triple row chains for this purpose and they were indistructible.
