In reply to dunc56:
> (In reply to mike kann) The argument is, why carry another 100kg of driveshafts diffs etc and lose 5% MPG from friction, all for the 1 time in a year when you actually need 4WD. Audis are renowned for understeer anyway aren't they ? So it would be a very FWD experience.

I'd sort of agree with this^
I live in the country and do get snowed in a few days each year, the 4wd does come in handy at that time of the year.
That said, I got by fine when I had a 2wd Golf...
There are times when 4wd is useful, but those times don't come up often enough to cancel out the minus points you've mentioned.
The only reason I have 4wd on my car is because I bought a used car and by doing that you often have to compromise on the spec - my car was the nearest spec'ed to what I wanted, but would have happily paid a bit more for a non-4wd one.
I also test drove a 2wd version of my car with 30bhp less, back to back with the car I bought. The less powerful car didn't feel any slower, in fact if anything it maybe felt a tad faster(!).
